Answer:
The coefficient of kinetic friction is 1.03
Explanation:
<u>Step 1:</u> Given data
⇒ mass of the block = 0.600 kg
⇒ elastic constant k = 20 N/m
⇒ The spring is compressed by 20.0 cm (=x) = 0.2 m
⇒ Once it loses contact with the spring, the block travels a distance 33 cm
<u>Step 2:</u> Calculate the potential energy
Ep = 1/2 * k * x²
Ep = 1/2 * 20N/m * (0.2m)²
Ep = 0.4 Nm
<u>Step 3:</u> Calculate the coefficient of kinetic friction
At the end of the movement Potential energy = work
W = Ep = 0.4Nm = µx * m * g* x
µx = Ep / (m*g*x)
µx = 2Nm / ( 0.6 kg * 9.81 m/s² * 0.33m)
µx = 1.03
The coefficient of kinetic friction is 1.03
Answer:
rift valleys are created is the correct answer:)
Explanation:
A.) amplitude (amplitude equates to the volume of a sound wave, frequency equates to the note that is played)
There are only two things you can do to increase the work output of a machine:
1). Increase the work INput to the machine.
2). Make the machine more efficient ... do things like lubricating it better to eliminate some internal friction.
Crystalline Solids.
In theses solids the molecules or ions are arranged in a pattern.
The smallest repeating structure is called a unit cell.Thses unit cells combine to from crystal latttices.
Salt and minerals are such an example.
Thses are also called true solids
