Answer:

Work occurs when a force acts on an object and causes a displacement of that object.

Explanation:

a . Force applying over a distance or in other words force causing the movement (displacement) of an object is known as Work.

b. An activity with mental or physical effort is done in order to achieve a result is called work.  

c. A constant force integrates the product of the force and distance.

Ex : 1) when the body moves in the direction of force

2) shooting a bullet

3) Pushing a car horizontally from rest

4)walking up stairs

5) sawing a log.

Answer:

Work occurs when a force acts on an object and causes a displacement of that object.

Explanation:

If F is the force applied to an object and d is the displacement caused due to this force, then the amount of work done by it is given by :

W = F × d

Where

F is the force applied

d is the displacement

Work done also depends on the angle between force and the displacement. So, the correct option is "Work occurs when a force acts on an object and causes a displacement of that object".

<h3>What is sound wave?</h3>

A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid substance). Pressure waves are produced when an item vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disrupt the particles next to them, and so on. Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.

Two waves are superposed. one wave has an amplitude of 5 cm, and other has an amplitude of 4 cm. What is the resultant amplitude
Vsevolod [243]
If both waves have the same wavelength, then the amplitude of
their sum could be anything between 1 cm and 9 cm, depending
on the phase angle between them.

If the waves have different wavelengths, then the resultant is a beat
with an amplitude of 9 cm.
