Answer:

Smaller forces are easier on your legs and you prefer to land on soft grass. Momentum/impulse explanation: Whether you land on concrete or soft grass, your change in momentum will be identical. A hard surface that brings you to a stop in 0.01 s requires a much larger force of 15,000 N.

Explanation: As the power following up on an object increases, the speed of acceleration is increased. As the mass of the article is expanded, the speed increase of the item is diminished.

Answer:

Vf = 23 m/s

Explanation:

First we need to find the distance covered by the motorcycle 2 when it passes motorcycle 1. Using the uniform speed equation for motorcycle 1:

s₁ = v₁t₁

where,

s₁ = distance covered by motorcycle 1 = ?

v₁ = speed of motorcycle 1 = 6.5 m/s

t₁ = time = 10 s

Therefore,

s₁ = (6.5 m/s)(10 s)

s₁ = 65 m

Now, for the distance covered by motorcycle 2 at the meeting point. Since, the motorcycle started 50 m ahead of motorcycle 2. Therefore,

s₂ = s₁ + 50 m

s₂ = 65 m + 50 m

s₂ = 115 m

Now, using second equation of motion for motorcycle 2:

s₂ = Vi t + (1/2)at²

where,

Vi = initial velocity of motorcycle 2 = 0 m/s

Therefore,

115 m = (0 m/s)(10 s) + (1/2)(a)(10 s)²

a = 230 m/100 s²

a = 2.3 m/s²

Now, using 1st equation of motion:

Vf = Vi + at

Vf = 0 m/s + (2.3 m/s²)(10 s)

Vf = 23 m/s

Explanation:

An analog signal has some feature that is a continuous function of the program material being transmitted. It may take on any of a range of values.

In radio, amplitude, frequency, or phase are features of the radio signal commonly modulated when transmitting an analog signal.

__

A digital signal has some feature that is a discrete function of the program material being transmitted. It may take on any of a specific set of values.

A digital radio signal typically uses some combination of amplitude, frequency, and phase to represent a discrete state being transmitted. Only specific values of these are used by the transmitter.

(The receiver generally has to deal with corruption of the signal by the transmission channel, so the received set of values may not correlate well with those intended at the transmitter. This is why error-correcting codes are often used with digital signal transmission.)

_____

Additional comment

Analog radio signals are generally transmitted using a carrier wave at a specific frequency (or in some specific frequency range, in the case of frequency modulation). Processing techniques may be used at the transmitter to limit the bandwidth used in the transmission. One commonly-used technique is to limit the transmitted spectrum to one side of the carrier wave frequency. (This is called "single side-band" radio.)

Digital signals offer the opportunity to transmit different bits of the information at different frequencies. Sometimes, "frequency hopping" is used, so that the transmitted carrier wave jumps around from one frequency to another in a predetermined pattern. The effect of this is to spread out the spectrum of the transmitted signal so that average power in any frequency band is significantly reduced. In fact, it may be indistinguishable from background noise, except by a receiver that tunes to the carrier wave in the predetermined frequency pattern.

Answer:

It isn't A.

Explanation:

I got it wrong with the answer A.

it is harder to swim in water with a current (like the ocean) than in contained water (like a pool) because Still water is an immovable object, but currents have their own momentum. The correct option is D.

Newton's first law of motion, also known as the law of inertia, states that "an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force."

This means that an object will continue to move in a straight line at a constant speed unless an unbalanced force acts upon it. In addition, if an object is at rest, it will remain at rest unless acted upon by an unbalanced force.

The law of inertia can be applied to many situations. For example, if a book is sitting on a table, it will remain at rest until a force is applied to it. Similarly, if a ball is rolling on a flat surface, it will continue to roll at a constant speed in a straight line unless a force, such as friction, slows it down or changes its direction.

This law is fundamental to understanding the behavior of objects in motion, and it forms the basis for the other two laws of motion formulated by Sir Isaac Newton.

Here in the Question,

Swimming in a pool versus swimming in the ocean, the difference lies in the presence of a current in the ocean.

The current in the ocean has its own momentum, and when a swimmer enters the water, they are faced with an additional force that they must overcome to move forward. This means that the swimmer must apply more force and use more energy to overcome the force of the current and move forward in the water.

In still water, on the other hand, there is no external force acting on the swimmer, so they only have to overcome the resistance of the water itself to move forward.

Therefore, The correct answer is D i.e Still water is an immovable object, but currents have their own momentum.

Answer:

Vy = V sin theta = 30 * ,574 = 17.2 m/s

t1 = 17.2 / 9.8 = 1.76 sec to reach max height

Max height = 17.2 * 1.76 - 1/2 * 4.9 * 1.76^2 = 15.1 m

H = V t - 1/2 g t^2 = 1.2 * 9.8 * 1.76^2 = 15.1 m

Time to fall from zero speed to ground = rise time = 1.76 sec

Vx = V cos 35 = 24.6 m / sec     horizontal speed

Time in air = 1.76 * 2 = 3.52 sec before returning to ground

S = 24.6 * 3.52 = 86.6 m

Considering the definitipn of current, voltage, power, and Ohm's law,

The flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.

The conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.

Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.

This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.

The resistance that is measured in ohms.

Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.

Mathematically, Watt's law is expressed:

[tex]I=\frac{V}{R}[/tex]

So if you want to find resistance, the expression for its calculation is:

[tex]R=\frac{V}{I}[/tex]

In this case, you know:

Replacing:

[tex]R=\frac{5.26 V}{0.41 A}[/tex]

Solving:

R= 12.8 ohms

Habiba is right. The resistance is 12.8 ohms.

Explanation:

The relative motion of the train next to her is the motion of the other train in her rest frame.

As the other train leaves, it seems to Sunita as if her train is moving backwards

Reason:

The motion of the train Sunita is taking is given by the rate of movement of

objects outside the train from the front side of the train towards the back

side of the train, that way she can tell that the train is moving.

The motion of the other train from the rear side of the train from the rear

side of the train to the front side is a reverse motion to what Sunita

observes when the train is moving forward. Therefore, as the other train

leaves, it seems to Sunita as if her train is moving backwards.
