Newton taught us that Force = (mass) x (acceleration)
Force = (0.2) x (20) = <em>4 newtons</em> .
Something to think about: The ball can only accelerate while the club-face
is in contact with it. Once the ball leaves the club, it can't accelerate any more,
because the force against it is gone.

Answer:
θi = 47.7°
Explanation:
The formula for the refractive index is as follows:
where,
n = refractive index = 1.75
θi = angle of incidence = ?
θr = angle of refraction = 25°
Therefore,
<u>θi = 47.7°</u>
Because of the parameters that we are given in the question, the right current formula that should be used for this physics problem is:
I = P/V
Where:
I = Current
P = Power and
V = Voltage
From the question, we are told that:
P = 16 W
V = 9 V
Thus, current = P/V = 16/9 = 1.78
Therefore, The current used by the camcorder is 1.8 Amphere.
