<span>The sprinter is advised to reduce his speed slowly after
completing the race because of the power that is needed when the stoppage is
down in a faster manner could be very great. This would translate to the great
usage in gasoline. Also, the inertia of the vehicle is quiet high so it is hard
to stop it very suddenly. </span>
C) it decreased
because atmospheric pressure decreases as we move up.
Answer:
U = 102.8 J (100 J to two significant digits)
Explanation:
potential energy converted = 20(9.8)(1.8) = 352.8 J
kinetic energy at base of track = ½(20)5.0² = 250 J
energy (work) of friction 352.8 - 250 = 102.8 J
Answer:
The distance is 1.69 m.
Explanation:
Given that,
First charge 
Second charge 
Distance = 3.25 m
We need to calculate the distance
Using formula of electric field





Put the value into the formula





Hence, The distance is 1.69 m.
