Answer:
see that there is no dependence on speed, so the work remains constant
Explanation:
Work is defined by the expression
W = F. d
where the boldface indicates vectors, this equation can be written in scalar form
W = f d cos θ
where θ is the angle between force and displacement.
We see that there is no dependence on speed, so the work remains constant
The power is
P = W / t
P = f d / t
p = F v
we see that the power is the one that depends on the speed of the body
Coriolis effect
That’s what I remember from whenever I was in that unit.
Answer:
i think answer is c
Explanation:
as formation water from steam condensed release heat
else all need heat
ans: B
Kinetic energy = 
= 
= 50J
ps. the height will only affect its potential energy, not kinetic.
