Answer:
Zero
Explanation:
<em>The resultant force acting on the ball would be </em><em>zero.</em>
<u>Since only two forces were acting on the tennis ball and these forces negate and cancel each other in magnitude, the resultant effect on the tennis ball would be zero. </u>
Assuming that one of the forces is 5N and acting from the positive side and the other force is also 5N but acting from the negative side.
Resultant = -5 + 5 = 0 N
For the given wave speed, the frequency is 2.0 Hz
<h3>What is frequency?</h3>
The frequency is the number of cycles per second in the sinusoidal wave.
Given is the length of the string L = 40cm, the wave speed v =320 cm/s, then the wavelength is
λ =4L
λ =4 x 40 cm =160 cm.
The frequency is related to the wavelength as
f =v/λ
f =320/160
f=2.0 Hz
Thus, the frequency is 2.0 Hz.

Answer:
0.219N
Explanation:
Given data
mass= 7.3kg
acceleration= 0.03m/s^2
We know that
F=ma
substitute
F= 7.3*0.03
F= 0.219N
Hence the applied force is 0.219N
