<h2>Answer</h2>
Radius is 421 m.
<u>Explanation </u>
A car with a mass of 1,500 kg requires a centripetal force of 640 N to safely follow a circular curve in the road at 13.4 m/s. Therefore, for radius we use formula which is Fc = mv ^ 2 / r,
As mass = m = 1500kg,
Centripetal force = Fc = 640N,
Velocity = v = 13.4 m / s
By putting values, Fc = mv ^ 2 / r,
r = mv ^ 2 / Fc,
=> r = ( 1500kg ) . ( 13.4 m / s) ^ 2 / 640,
=> r = ( 1500kg ) . ( 179.56 ) / 640,
r = 269340 / 640,
=> r = 420.84 m.
Radius is 421 m.
C.even though there is almost no material in the interstellar medium, but do transfer energy.
Explanation:
Light waves travels through space even though there is almost no material in the interstellar medium but do transfer energy.
A wave is any disturbance that transmits energy from one place to another.
- Light is a form of wave which belongs to the electromagnetic spectrum.
- They are propagated transverse to their source of energy.
- These electromagnetic waves are special types of waves.
- They are distinct because they do not require a material medium for their propagation unlike other waves.
- In the interstellar medium. a vacuum is in place.
- There are no matter that can be used for propagating waves.
- Light waves still passes through because they do not require any medium to propagate.

B. all of nature follows uniform, unchaining laws.
Answer:
A
Explanation:
the answers are all not good, but I would say A is the best
Answer:

Explanation:
given,
Radius of earth = 6400 Km
speed of a physics student in Miami, Florida, at latitude 26° = v
time period of rotation = 24 hour = 24 × 3600
= 86400 s
distance = speed × time



hence, the velocity of the student is equal to
