Answer:
THE LAW OR PRINCIPLE OF SUPERPOSITION; States that when two identical waves are brought, the resultant disturbance is the algebraic sum of the individual disturbances of the two waves.
Explanation:
Most stationary waves are obtained as a result of the combination or superposition of an incident wave and it's reflected wave. Like in music, they result from the stationary waves of plucked strings leading to the Superposition law.

Answer:
Furniture mover.
Explanation:
A strain is a soft tissue injury that happens on the muscle or tendon - it could occur on several parts of the body, such as hands or legs. When it is acute, an incident might have caused it and proper rest would let it heal.
This type of injury could happen to athletes, but those who are at risk are those who are involved in sports field such as wrestling and football. Thus, baseball players are a lower risk.
Bank tellers and heart surgeons would not suffer from this type of injury - they are more likely to suffer from chronic than acute strains do to the overuse of certain muscles.
The group that is at the highest risk are people who move heavy objects - such as furniture mover.
Answer:
The number of electrons need to leave each object is
Explanation:
Given that,
Mass of object = 6.22 kg
Distance = 1.02 m
We need to calculate the number of electron
Using formula of electric force
....(I)
We know that,
Put the value of q in equation (I)
.....(II)
Using gravitational force
.....(III)
Equating equation (II) and (III)
....(IV)
Put the value in the equation(IV)
Hence, The number of electrons need to leave each object is
