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
Uhhh I’m not really sure of the answer i think it’s stratosphere
The answer is : D
Reasoning:
Homeostasis is the body’s balance
The speed of sound on planet is 210 m/s.

What is Oscillation?</h3>
Oscillation is the repeating or periodic change of a quantity around a central value or between two or more states, often in time. Alternating current and a swinging pendulum are two common examples of oscillation.
There are 3 main types of Oscillation –
- Free
- damped
- forced oscillation
f = frequency = 600 Hz
lambda = wavelength = 35 cm = 0.35 m
Now,
V = speed = f × lambda = 210 m/s
Hence, speed of sound on planet is 210 m/s.
