Drift velocity is equal to displacement of the moving object per unit time. The SI unit for displacement is meters while that of time is second. Hence the derived SI unit of velocity is meter per second. This also applies to electron mobility which relates to the displacement per unit time of a moving electron
<span>During winter for a given hemisphere, solar radiation reaches the lowest period of its annual cycle due to the tilt of the earth on its axis. As the earth rotates around the sun, this tilt occludes a portion of the energy released by the sun as it diffuses in the atmosphere.</span>
Answer:
So percentage error will be 2 %
Explanation:
We have given initial value of acceleration due to gravity
And final value of acceleration due to gravity
We have to find the percentage error
We know that percentage error is given by
So %
Answer:
Temperature will be 305 K
Explanation:
We have given The asteroid has a surface area
Power absorbed P = 3800 watt
Boltzmann constant
According to Boltzmann rule power radiated is given by
So temperature will be 305 K
