Answer:
Drop to half of the previous value
Explanation:
Energy stored in capacitor is inversly propotional to the distance between the plates.
The nail has become a temporary magnet, while the
bar magnet remains a permanent magnet.
Answer:
15.03 m
Explanation:
Given:
mass of the block, m = 7.25 kg
Angle, Θ = 28.5°
Initial speed of the block, v₀ = 15 m/s
let the distance traveled by the block be 's'
Now, applying the work energy theorem,
we have

on substituting the values in the above equation, we get

or

or

s = 15.03 m
Hence, the block will travel 15.03 m up the ramp
