1) The longitudinal waves move in parallel direction to the source of vibration. The transverse waves move in perpendicular direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.
2) Reflection occurs when waves bounce from a surface back toward the source. Refraction is when waves are deflected when the waves go through a substance.
3) The Law of Conservation of Energy
states that energy can neither be created
nor destroyed, it can only be transferred or
changed from one form to another.
Answer:
value of fs,max under the circumstances is
f = 42.56 N
Explanation:
The formula is µ = f / N, where µ is the coefficient of friction, f is the amount of force that resists motion, and N is the normal force. Normal force is the force at which one surface is being pushed into another.
So f = µN
f = 0.380 * 112
f = 42.56 N
Answer : The average value of current is
.
Explanation :
It is given that,
Net charge, q = 5 C
Time, t = 0.05 s
The electric current is defined as the rate of change of electric charge.



or

The average current is
.
Hence, this is the required solution.
