A bird flies west with a velocity of 8 m/s . How long does it take the bird to travel a horizontal distance of 400 meters ?
1 answer:
The time taken is 50 s
Explanation:
For a body moving in uniform motion (= at constant velocity), the velocity of the body is given by:
where
v is the velocity
d is the distance covered
t is the time taken
In this problem, we have a bird travelling with uniform motion. We know that:
v = 8 m/s is the velocity of the bird
d = 400 m is the distance travelled
Solving for t, we find the time the bird needs to cover this distance:

"The equation can be used to calculate the power absorbed by any surface" statement concerning the Stefan-Boltzmann equation is correct.
Answer: Option A
<u>Explanation:</u>
According to Stefan Boltzmann equation, the power radiated by black body radiation source is directly proportionate to the fourth power of temperature of the source. So the radiation transferred is absorbed by another surface and that absorbed power will also be equal to the fourth power of the temperature. So the equation describes the relation of net radiation loss with the change in temperature from hotter temperature to cooler temperature surface.
So this law is application for calculating power absorbed by any surface.
