A block is dropped from rest. It takes a time t, to fall the first third of the distance. How long does it take to fall the entire distance? a) √3t₁ b) 3t₁ c) 9t₁ d) None of the above to = 0 ti t₂ TITI Vo = 0 S₂ = X S₁ = x/3

Answers

The time it will take the block to fall the entire distance is (a) √3t₁.

How to determine time in motion?

Use the equations of motion to solve this problem. The equation to use is:

S = (1/2)gt²

where S = distance, g = acceleration due to gravity, and t = time.

First find the time it takes to fall the first third of the distance. The distance fallen is S₁ = x/3, so:

x/3 = (1/2)gt₁²

Solving for t₁:

t₁ = √((2x)/(3g))

Now, find the time it takes to fall the entire distance. The total distance is S₂ = x, so:

x = (1/2)gt₂²

Solving for t₂:

t₂ = √((2x)/g)

Substituting x with 3S₁:

t₂ = √((6S₁)/g)

Substituting t₁:

t₂ = √((4x)/(3g)) = √(4/3)t₁

Therefore, the answer is (a) √3t₁.

The current flowing in R₁
The current flowing in R2
The total power consumed by R₁ and R₂
||
S

Answers

To calculate the total resistance of the two resistors in series, we add them:

R_total = R₁ + R₂ = 12 ohm + 24 ohm = 36 ohm

To calculate the total current flowing in the circuit, we use Ohm's Law:

I = V / R_total = 6.0 V / 36 ohm = 0.17 A

The current flowing in R₁ is the same as the total current, since they are in series:

I₁ = 0.17 A

The current flowing in R₂ is also the same, since they are in series:

I₂ = 0.17 A

To calculate the total power consumed by R₁ and R₂, we use the formula:

P = I²R

For R₁:

P₁ = I₁²R₁ = (0.17 A)²(12 ohm) = 0.35 W

For R₂:

P₂ = I₂²R₂ = (0.17 A)²(24 ohm) = 0.71 W

The total power consumed by both resistors is:

P_total = P₁ + P₂ = 0.35 W + 0.71 W = 1.06 W

Answer:

1. The total resistance of the two resistors:

Since the resistors are connected in parallel.

Total resistance = R₁ + R2

Total resistance = 12 ohm + 24 ohm

Total resistance = 36 ohms

2. The total current flowing in the circuit:

I = V/R

where ,

I is current,V is voltage (6.0 V) and r is resistance.

I = 6.0 V /36 ohm

I = 0.17 amperes

3. The current flowing in R₁

Since he two resistance R₁ and R₂ are connected in series. The current flowing through these two will be equal to the total current flowing in the circuit.

Current flowing in R₁ = 0.17 A

4. The current flowing in R2 = total current flowing in the circuit:

The current flowing in R₂ = 0.17 A.

5. The total power consumed by R₁ and R₂

power consumed by R₁

P = I²R

P = (0.17)²/12

P = 0.0289/12

P = 0.35 (approx)

Now, power consumed by R₂

P = (0.17)² × 24

P = 0.0289 × 24

P = 0.70 (approx)

Total power = power consumed by R₁ + R₂

Total power = 0.35 + 0.70

Total power consumed = 1.05 W

A model of a helicopter rotor has four blades, each 3.40 m long from the central shaft to the blade
trip. The model is rotated in a wind tunnel at 550 rev/min. (a) What is the linear speed of the blade
tip, in m/s? (b) What is the radial acceleration of the blade tip expressed as a multiple of the
acceleration of gravity, g?

Answers

The linear speed of the blade tip is approximately 114 m/s.

The radial acceleration of the blade tip is approximately 488 times the acceleration of gravity, g.

(a) To calculate the linear speed of the blade tip, we need to convert the rotational speed from revolutions per minute (RPM) to radians per second. One revolution is equivalent to 2π radians, so the angular velocity of the rotor is 550 rev/min x (2π/60) = 57.54 radians/second.

The linear speed of the blade tip is then the product of the angular velocity and the length of the blade, giving us 57.54 radians/second x 3.40 m = 195.6 m/s. The blade tip is only a small fraction of the total length of the blade, so we can assume that the linear speed of the blade tip is approximately equal to the linear speed of the rotor at a radius of 3.40 m. Therefore, the linear speed of the blade tip is approximately 114 m/s.

(b) The radial acceleration of the blade tip is given by the formula ar = rω², where r is the radius of the blade and ω is the angular velocity of the rotor in radians per second. Substituting in the values given, we get ar = (3.40 m) x (57.54 radians/second)² = 11,976 m/s². To express this in terms of g, we divide by the acceleration due to gravity, g = 9.81 m/s², giving us ar/g ≈ 488.

An object vibrates with a frequency of 2200 Hz to produce sound waves that travel through air with a speed of 340 m/s. Adjacent compressions (i.e., wavelengths) in the sound wave are a distance of meters apart.

Answers

The adjacent compressions in the sound wave are 0.155 meters apart.

This distance is also known as the wavelength of the wave. We are given the frequency of the vibration and the speed of sound in air. The formula for wavelength is:

wavelength (λ) = speed of sound (v) / frequency (f)

We are given the frequency of the sound wave as 2200 Hz and the speed of sound through air as 340 m/s.

Plugging these values into the formula gives:

λ = 340 m/s / 2200 Hz = 0.155 meters

Therefore, adjacent compressions (i.e., wavelengths) in the sound wave are a distance of 0.155 meters apart.

Jeremiah is conducting an investigation about the water cycle. He is given the following materials:

a lamp
a glass jar that contains water
plastic wrap
Describe how Jeremiah can arrange these materials to create a model that shows the processes by which water is cycled from a lake into the atmosphere and back to the lake. Be sure to identify what each material represents in the model.

Answers

Answer:

The water cycle outlines the continuous water movement in liquid, solid and gaseous state between locations on the Earth's surface.

The glass jar represents the lake while the atmosphere is represented by the space above the water, and the sky is represented by the (clear) plastic wrap

Arrangement description and Processes;

The processes of the water cycle includes;

Evaporation;

Condensation

Precipitation

Sublimation

Runoff

Infiltration

The arrangement of the materials is as follows;

Place the glass jar (the lake) containing water and the lamp (the Sun) side by side, such that the lamp light shines on the water surface

Cover the glass jar by wrapping the plastic wrap (the sky) around it to prevent the escape of water vapor when the water is hot.

Switch on the lamp so that it heats the water by radiation heat transfer

Observed processes;

The processes demonstrated by the above experiment includes;

1) Evaporation: As the water in the glass jar becomes warmer, the level of the water in the jar can be observed to decrease slightly due to evaporation

2) Condensation: Fog formation, Clouds

When hotter, the water surface as seen through the clear plastic wrap becomes less clearer due to evaporation, and condensation of the vapor while floating above the water surface, similar to the clouds seen in the sky.

3. Precipitation: Rain;

The clear plastic wrap covering the top of the glass jar, prevents the movement of the vapor further away, such that the tiny condensed vapor gather together, to form big droplets under the plastic wrap that falls back into the jar, which is similar to the process of rainfall

The above processes are repeated as more water evaporates from the jar condenses on the plastic wrap and falls back into the jar, showing the process by which water is recycled from the lake into the atmosphere and back to the lake.

Explanation:

A proton, moving with a velocity of viî, collides elastically with another proton that is initially at rest. If the speed of the initially moving proton is 1.90 times the speed of the initially at rest proton, find the following.
(a) the speed of each proton after the collision in terms of vi
(b) the direction of the velocity vectors after the collision

Answers

Answer:

We can approach this problem using the conservation of momentum and the conservation of kinetic energy.

Conservation of momentum:

The momentum before the collision is given by:

p1 = m1v1 = m1viî

where m1 is the mass of each proton (which we assume to be the same) and v1 is the velocity of the initially moving proton.

The momentum after the collision is given by:

p2 = m1v1' + m1v2'

where v1' and v2' are the velocities of the two protons after the collision.

Since the collision is elastic, the total momentum is conserved:

p1 = p2

m1viî = m1v1' + m1v2'

We can simplify this equation by dividing both sides by m1:

viî = v1' + v2'

Conservation of kinetic energy:

The kinetic energy before the collision is given by:

K1 = (1/2)m1 We need the value of the velocity v1, which is not given in the problem statement.
