The answer is point b because vertical velocity is zero at the maximum height
Answer:
8100W
Explanation:
Let g = 10m/s2
As water is falling from 60m high, its potential energy from 60m high would convert to power. So the rate of change in potential energy is
or 9000W
Since 10% of this is lost to friction, we take the remaining 90 %
P = 9000*90% = 8100 W
Answer: D
The final velocity of the object will be directed north of east
Explanation:
Answer:
A wave in which the medium vibrates at right angles to the direction of the propagation is called transverse wave.
