Answer:
The solution is given in the picture attached below
Explanation:
A periodic transverse wave has an amplitude of 0.20 meter and a wavelength of 3.0 meters. If the frequency of this wave is 12 Hz
1 answer:
The speed is 36 m/s
<u>Explanation:</u>
Speed of any wave is the measure of how fast the wave is propagating or travelling in medium. So, the speed of the wave can be calculated as the product of frequency with wavelength of that wave.
Thus, speed is directly proportional to the frequency and wavelength of a wave.
<u>Given data:</u>
frequency of the wave is given as 12 Hz
wavelength is given as 3 m
Therefore, the speed will be
Speed = 12 × 3 = 36 m/s
Thus, the speed of the transverse wave is 36 m/s.

The coefficient of static friction between the chair and the floor is 0.67
Explanation:
Given:
Weight of the chair = 25kg
Force = 165 N (F_applied)
Force = 127 N (F_max)
To find: Coefficient of static friction
The “coefficient of static friction” between a chair and the floor is defined as the ration of maximum force to the normal force acting on the chair
μ_s=
The F_n is equal to the weight multiplied by its gravity
∴=mg
Thus the coefficient of static friction changes as
μ_s=
μ_{s} =
= 0.67
