Imagine a crowd of people al jumping around in a room blindfolded. they will bump into each other and the walls. molecules behave the same way as a result of their temperature. the hotter the temperature, the more jumping and the greater the 'pressure' on the walls.
d = displacement
a triangle, displacement = hypotenuse = phytagoras
Water surface waves are examples of waves that are both longitudinal and transverse waves. As the wave travels through the water, a clockwise circles is observed. Therefore, the answer to this item is letter D. All the rest of the choices do not describe the water surface waves.
It is B) Wavelength, because it measures the "length" between "waves", therefore, wavelength.
Given:
s(distance)= 20 meters
F(force)=200N
Now we know that
work done= Force applied x distance
Substituting the given values in the above formula we get
Work done= 20 x 200= 4000J
