Answer:
R = 73.25 m
Explanation:
We have,
Initial speed of the ball is 27 m/s
It is projected at an angle of 40 degrees
The maximum range of the ball is given by :

Plugging all the values we get :

So, the maximum range of the ball is 73.25 m
That's the "Atomic Mass" of the atom.
Answer:
62.7 VA
Explanation:
The apparent power (power supplied by the source) of an AC circuit is determined by

The impedance(Z) depends on the frequency, but in this case it is given to us that it is 102 ohms at this frequency.
So:

Answer:
centripetal force is a net force that acts on an object to keep it moving along a circular path and elastic force acts to return a spring to its natural length
