A bicycle and rider travel along a road. Which is true?A. The bicycle and the rider undergo translation.
B. Only the rider undergoes a translation.
C. Only the bicycle undergoes translation.
D. Neither the bicycle nor the rider undergoes a translation.

Answers

Answer:

A. The bicycle and the rider undergo translation.

Explanation:

When a rider is riding his bicycle along the road, the wheels of the bicycle will rotate. This rotation of wheels translates both the rider and the bicycle in space.

So the correct answer is option A

A bicycle and rideer travel along a road. the true about the sentence is: a. the bicycle and the rider undergo translation. The rider moving because you have to push the pedals and make the bike moves too.

A 60-kg person is traveling in a car moving at 16 m/s, when the car hits a barrier. The person is not wearing a seat belt, but is stopped by an air bag in a time interval of 0.20 s. Determine the average force that the air bag exerts on the person?

Answers

Using conservation of momentum, we can solve for the force that the air bag exerts on the person.

Recall the equation for momentum (p):

p = mv = F*dt

We can solve for total momentum, then divide by out time interval. This gets us:

(60kg)(16m/s) = F(0.2s)F = 4800N

F = 4800N

Which of the following is most closely related to the specific heat of a substance?a. its temperature
b. its melting point
c. its amount of heat transferred
d. its rate of change in temperature

Answers

The following that is is most closely related to the specific heat of a substance is its rate of change in temperature. The answer is letter D. The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 Kelvin is called the specific heat. The answer is a. For example, water. Water has a specific heat of 4.18 Joules per kilogram per Kelvin. This means that in order for water to change from one state to the other at one kelvin, it needs 4.18 Joules of energy per one kilogram of water. But it does not apply to changes in phase, because the heat added or removed during a phase change does not change the temperature of a substance.

How does a shorter wavelength affect the frequency of a wave?

Answers

The product of (wavelength) x (frequency) is always the same number ... the speed of the wave. So if one of them decreases, the other one must increase in order to keep the product the same. Shorter wavelength means higher frequency.
