When two equal forces act on an object in opposite directions, they are known as balanced forces.

The balanced force is a system of forces that acts on an object without causing any change in motion. Balanced forces are those that do not change an object's speed or direction. If the forces acting on an object are balanced, the net force will be zero. When the net force is zero, the object is stationary or moving with a constant velocity.

Unbalanced forces are those that produce a change in an object's motion. Unbalanced forces are those that cause an object to speed up, slow down, or change direction. An object will only move if the net force acting on it is non-zero.

Two or more forces that are equal in size but opposite in direction are known as equivalent forces. When two or more equivalent forces are acting on an object, they cancel each other out, and the net force is zero.

Parallel forces are forces acting on an object in the same direction. When two or more parallel forces are acting on an object, they combine to form a resultant force that is equal to the sum of the individual forces. The direction of the resultant force is the same as that of the individual forces.

(a) The magnitude of force required to give a helicopter of mass 2M an acceleration of 0.10 g upward is 1.962M N.

(b) The work done by this force as the helicopter moves a distance h/2 upward is 0.981M h Joules.

(a) To find the force required to give the helicopter an upward acceleration of 0.10 g, we can use the following equation:
Force (F) = Mass (m) × Acceleration (a)

The acceleration due to gravity (g) is approximately 9.81 m/s². Therefore, 0.10 g is equal to 0.10 × 9.81 m/s², which is 0.981 m/s².

The helicopter's mass is given as 2M. So, we can plug the values into the equation:

F = 2M × 0.981 m/s²

F = 1.962M N (Newtons)

So, the magnitude of the force required is 1.962M N.

(b) To find the work done by this force as the helicopter moves a distance of h/2 upward, we use the equation:

Work (W) = Force (F) × Distance (d) × cos(θ)

Since the force is acting vertically upward and the helicopter is moving in the same direction, the angle (θ) between the force and the distance is 0°, and the cosine of 0° is 1.

The force (F) is 1.962M N and the distance (d) is h/2. Therefore:

W = 1.962M N × (h/2) × 1

W = 0.981Mh J (Joules)

The work done by this force as the helicopter moves a distance h/2 upward is 0.981Mh Joules.

The brightness of the three bulbs compared to each other is bulb A is brighter than B and C which have the same brightness.

According to Ohm's law, the current passing through a conductor is directly proportional to the potential difference applied across its ends and inversely proportional to the resistance of the conductor. So, the bulb with the least resistance will draw more current and shine brighter as compared to the other two bulbs. Thus, the bulb with the least resistance will be the brightest.

Besides, it is mentioned that the battery maintains a constant potential difference between its terminals. It means that the internal resistance of the battery is negligible. Therefore, the voltage across the three bulbs will be the same, and the current passing through each bulb will depend on the resistance of the individual bulbs.

In the given circuit, the brightness of the three bulbs will be different from one another. Bulb А is brighter thаn B аnd C which hаve the sаme brightness. This is because the correct thru А is lаrger becаuse its pаrаllel pаth hаs less resistаnce thаn the B аnd C pаth.

Answer:

Momentum is the product of mass of a body and its velocity.

Initially before collision and after collision, velocity changes but mass is a constant factor. Therefore, only one term changes by a constant change hence momentum gained initially, and that gained finally is equal

If the moment of interia is 6.0 kg-m2 . 1.50 N-m the torque applied for the first two seconds.

As per the question statement, the moment of inertia is 6.0 kg-m².

Hence, to determine the torque applied for the first two seconds, we must know the angular acceleration.

Therefore, the angular acceleration is given by:

α=τ/I

Where α is the angular acceleration, τ is the torque, and I is the moment of inertia.

Substituting the given values, we get:

α=τ/I

⇒αI=τ

⇒τ=αI

The moment of inertia I is given to be 6.0 kg-m².

Further, the torque can be determined by calculating the angular acceleration α.

However, the angular acceleration is not provided in the question statement. Hence, we need to make some assumptions to determine α.

Let us assume that the angular acceleration is uniform i.e., constant.

Also, we assume that the initial angular velocity is zero.

Using these assumptions, we can calculate the angular acceleration as:

α=2θ/[tex]t^2[/tex]

Where θ is the angular displacement and t is the time interval.

Since the question statement does not provide the value of θ,

let us assume that the object has rotated by 90 degrees in the first 2 seconds.

Therefore, θ = 90° = π/2 radian.

Substituting the given values, we get:

α=2θ/[tex]t^2[/tex]

α=2π/[tex]2^2[/tex] =π/4\,rad/[tex]s^2[/tex]

Therefore, the angular acceleration α is π/4 rad/s².

Substituting this value along with the given moment of inertia I, we get:

τ=αI

τ=(π/4) x 6.0

τ=1.50\,N-m

Therefore, the torque applied for the first two seconds is 1.50 N-m, rounded off to two decimal places.

When an object rolls without slipping down an inclined plane, the true statement(s) about static friction force are: It provides the torque to cause the angular acceleration and it goes against gravity to reduce the acceleration caused by gravity. The correct answer is B and E.

Friction is the force that opposes relative motion between surfaces in contact. It is also called a contact force because it operates between the surfaces in contact when they're in motion or when a force tries to move them relative to one another.

An inclined plane is a simple machine that consists of a sloping surface that connects a lower point to a higher point. It is one of the six classical simple machines that is used to reduce the effort needed to raise a weight to a certain height.

Rolling without slipping is a combination of translational motion (movement in a straight line) and rotational motion (movement around an axis) without any slipping occurring between the surfaces in contact. A wheel or any other circular object rolls without slipping when its forward motion is the same as its rotational motion.

Static friction is the force that keeps an object at rest or in a state of uniform motion on a surface when a force is applied on it. When two surfaces are in contact, static friction is the force required to overcome the sticking between them that resists motion.

The paradox is this: if a horse pulls on a cart, and the cart pulls back on the horse with an equal magnitude force,  either possibly begin to move because the force balance.

The paradox mentioned here is resolved through the consideration of motion's relation to the interaction between objects. In order to move an object, force is required. When a force is applied to an object, it may either accelerate or decelerate. When a horse pulls a cart, the horse pulls with a force that is greater than the force the cart pulls back with, allowing the cart to move forward. However, the cart also pulls back on the horse with the same magnitude force, this force does not cause the horse to accelerate in the opposite direction. Instead, it is simply used to oppose the motion of the horse.

Therefore, both the cart and the horse can begin to move despite the force balance. The force balance is considered to be resolved in this situation since the force that the horse applies to the cart and the force that the cart applies back to the horse are not equal in nature, even though they are equal in magnitude.

It will take approximately 3.01 seconds for the pendulum bob to swing back to the person.

To answer this question, we need to find the period of the pendulum and then calculate the time it takes for the pendulum to swing back to the person.
Step 1: Calculate the period of the pendulum
The formula for the period of a simple pendulum is given by:
T = 2π√(L/g)
where T is the period.

L is the length of the cable (9.01 m), and g is the acceleration due to gravity (approximately 9.81 m/s²).
Step 2: Plug in the values and solve for T
T = 2π√(9.01 m/9.81 m/s²)
T ≈ 2π√(0.918 s²)
T ≈ 2π(0.958 s)
T ≈ 6.02 s
The period of the pendulum is approximately 6.02 seconds.
Step 3: Calculate the time it takes for the bob to swing back to the person
Since the period represents the time it takes for the pendulum to complete one full oscillation, and the person releases the bob at its highest point, the time it takes for the bob to swing back to the person is half of the period.

Therefore, we can calculate this time as follows:
Time to swing back = T/2
Time to swing back ≈ 6.02 s/2
Time to swing back ≈ 3.01 s.

Answer:

a)

i. A photoelectric current is registered on the microammeter when light of a certain wavelength is incident on the photocell because the energy of the incident photons of the light exceeds the work function of the metal surface of the photocell. This causes the photoelectrons to be emitted from the metal surface and a current to be registered on the microammeter.

ii. The current is found to increase with the light intensity is increased because as the intensity of the incident light increases, the number of photons incident on the metal surface also increases. This increases the number of photoelectrons emitted per unit time, resulting in an increase in the photoelectric current.

b)

i. When the incident light wavelength is increased, the photoelectric current falls to zero because as the wavelength of the incident light is increased, the energy of the incident photons decreases. When the energy of the incident photons becomes less than the work function of the metal surface, no photoelectrons are emitted and hence no current is registered on the microammeter.

ii. The current would still be zero if the light wavelength is kept the same and the intensity is increased because the energy of the incident photons is still less than the work function of the metal surface. Increasing the intensity of the incident light only increases the number of photons incident on the metal surface, but does not increase the energy of the individual photons. Hence, no photoelectrons are emitted and no current is registered on the microammeter.

The second-order maximum for light of wavelength 650 nm will be located approximately 15.6 mm from the central bright spot on the same screen.

Wavelength of light for the third-order maximum = 500 nm

Distance of third-order maximum from the central bright spot = 12 mm

Distance of screen from the slits = 1.3 m

Wavelength of light for the second-order maximum = 650 nm

Using the equation d sin θ = mλ, where d is the distance between the slits, θ is the angle between the line connecting the slits and the screen and the line connecting the bright spot and the central bright spot, m is the order of the bright spot, and λ is the wavelength of the light.

For the third-order maximum with 500 nm light:

d sin θ = mλ

d sin θ = 3 * 500 nm

d sin θ = 1500 nm

sin θ = 1500 nm / d

Given, distance from the central bright spot to the third-order maximum = 12 mm

Given, distance of screen from the slits = 1.3 m

Thus, tan θ = (12 mm) / (1.3 m)

θ = 0.013 radians

sin θ = 0.013

sin θ = 1500 nm / d

d = 1500 nm / sin θ

d = 1500 nm / 0.013

d = 115,384.6 nm

d = 115.4 µm

For the second-order maximum with 650 nm light:

d sin θ = mλ

d sin θ = 2 * 650 nm

d sin θ = 1300 nm

sin θ = 1300 nm / d

Using the value of θ calculated for the third-order maximum:

sin θ = 0.013

sin θ = 1300 nm / d

d = 1300 nm / sin θ

d = 1300 nm / 0.013

d = 100,000 nm

d = 100 µm

Thus, the distance from the central bright spot to the second-order maximum for light with wavelength 650 nm is approximately 100 µm, or 15.6 mm from the central bright spot on the screen.

According to time dilation, the elapsed time between two events is different for observers in relative motion to each other. The formula for time dilation is given by:

Δt' = Δt / sqrt(1 - v^2/c^2)

where Δt is the time interval measured by the observer in the rest frame, Δt' is the time interval measured by the observer in the moving frame, v is the relative velocity between the two frames, and c is the speed of light.

In this problem, the neutron is at rest relative to the first observer and its lifetime is measured to be 900 s. The neutron is moving relative to the second observer, and its lifetime is measured to be 2065 s. We want to find the velocity v of the neutron relative to the second observer.

We can use the time dilation formula twice, once for each observer:

Δt' = Δt / sqrt(1 - v^2/c^2)

For the first observer (rest frame of the neutron), Δt = 900 s and Δt' = 2065 s (measured by the second observer):

2065 = 900 / sqrt(1 - v^2/c^2)

Simplifying and rearranging:

(1 - v^2/c^2) = (900/2065)^2

1 - v^2/c^2 = 0.155

v^2/c^2 = 0.845

v/c = sqrt(0.845)

v = 0.919c

Therefore, the neutron is moving at a speed of 0.919 times the speed of light relative to the second observer.

If the intensity level by 10 identical engines in a garage is 100 dB,  the intensity level generated by each one of these engines is 90 dB. The correct answer is (b).

Here is a step-by-step explanation:
1. The intensity level (in decibels) of a combined sound is determined using the formula:Combined dB = 10 * log10(sum of the intensities of individual sounds).2. In this case, we have 10 identical engines producing the same intensity level, and their combined intensity level is 100 dB. Let x represent the intensity level of each engine. We can write the equation as:100 dB = 10 * log10(10 * intensity of one engine)

3. To find the intensity of one engine, we need to isolate x in the equation. First, divide both sides by 10:
10 = log10(10 * intensity of one engine)
4. Now, we can apply the inverse of the logarithm function, which is the power of 10 (10^x), to both sides:
10^10 = 10 * intensity of one engine
5. Divide both sides by 10:
10^9 = intensity of one engine

6. Finally, we need to convert this intensity back to decibels using the formula: x dB = 10 * log10(10^9)7. Apply the logarithm rule: x dB = 10 * 98. Calculate the value of x: x = 90 dB.So, the intensity level generated by each one of these engines is 90 dB.
