The water tank waves are transverse waves while the sound waves are longitudinal waves.
<h3>What is a wave?</h3>
A wave is a disturbance along a medium which transfers energy. We know that the water tank waves are transverse waves while the sound waves are longitudinal waves.
The difference between the two is that in the water waves, the direction of the wave motion is perpendicular to the disturbance while in the sound waves, the the direction of the wave motion is parallel to the disturbance.

Answer:
heterogeneous and homogeneous
Explanation:
Hetero you can separate whilst homo is combined and cant be separated
Great question. Albert Einstein proved that light acts as both a particle and a wave in his 1905 paper. This is called wave-particle duality.
With quantum mechanics, it is easy to prove that light behaves as both a particle and a wave.
When UV light hits a metal surface, it causes an emission of electrons. This "photoelectric effect" proves how light behaves.
Answer:
(a) 91 kg (2 s.f.) (b) 22 m
Explanation:
Since it is stated that a constant horizontal force is applied to the block of ice, we know that the block of ice travels with a constant acceleration and but not with a constant velocity.
(a)

Subsequently,

*Note that the equations used above assume constant acceleration is being applied to the system. However, in the case of non-uniform motion, these equations will no longer be valid and in turn, calculus will be used to analyze such motions.
(b) To find the final velocity of the ice block at the end of the first 5 seconds,

According to Newton's First Law which states objects will remain at rest
or in uniform motion (moving at constant velocity) unless acted upon by
an external force. Hence, the block of ice by the end of the first 5
seconds, experiences no acceleration (a = 0) but travels with a constant
velocity of 4.4
.

Therefore, the ice block traveled 22 m in the next 5 seconds after the
worker stops pushing it.
