Answer:
The coefficient of kinetic friction is .0204081633 and the firction acting upon the object is 1 N
Explanation:
To figure this out I started off with Newton's Second Law F= ma.
(11-x)=5*2. *x is the amount of force that kinetic friction applies on the object
x=1 N
Since F=1 and Friction=Normal-Force*Coifficient-Of-Friction
1=5g(mu)
mu=.0204081633
Hope this helps
Answer:
a
b
Explanation:
From the question we are told that
The spring constant is
The mass of the block is
Considering question a
Generally the weight of the block is mathematically represented as
=>
=>
Generally the force exerted on the spring is mathematically represented as
At equilibrium
=>
=>
=>
Considering question b
Generally the energy stored in the spring is mathematically represented as
Now the potential energy of the block before it is drooped is mathematically represented as
Generally from the law of energy conservation we have that
=>
=>
=>

Explanation:
The waves to be classified are missing from this questions. So, I'll just explain what Transverse and Longitudinal waves are together with examples for each.
A transverse wave is one in which the direction of travel of the wave/disturbance is perpendicular to the direction of the primary cause of the wave/disturbance. The oscillations/vibrations of the wave are perpendicular to the path of propagation or direction of the wave.
Examples include all electromagnetic waves (radio waves, infrared rays, visible light, ultraviolet rays, x-rays, gamma rays), waves in a string of guitar, ripples on the surface of water, seismic S waves etc.
A Longitudinal Wave is one whose direction of travel of the wave/disturbance is parallel to the direction of the primary cause of the wave/disturbance. The oscillations/vibrations of the wave are parallel to the path of propagation or direction of the wave.
Examples include sound waves, seismic P waves, ultrasound waves etc.
