As an object falls from rest, its gravitational energy is converted to kinetic energy
G.P.E = K.E = mgh
K.E = (80 Kg)(9.8 m/s²)(30 m)
K.E. = 23,520 J
Answer:
2 different types of precipitation is rain and snow.
Explanation:
The clouds will form... and the droplets that could be coming out is rain and snow.
The electric force (and the gravitational force too) is inversely proportional
to the square of the distance between the objects involved.
In this question, the distance is increased by a factor of (1.25/0.95) .
So the electric force will change by the factor of (0.95/1.25)² .
The new force is
(1.32 N) · (0.95/1.25)² = 0.762... newton (rounded)
Answer:
210m/s
Explanation:
To find the speed of wave you need to multiply the wave length with the frequency.
It's simple. You just need to apply formular onto problem.
