Convert 10mm to metres = 0.01m
Wave speed = frequency *wavelength
= 4Hz*0.01m
= 0.04 m/s
Hope this helps
Answer:
D
Explanation:
They looked at her hand and made a formal conclusion from that
Nswer
<span>Work done = Pressure * ΔV [ change in volume ] </span>
<span>If ΔV=0, then no work is done </span>
<span>Zero work thermodyanamic process is called ' isochoric process.' </span>
<span>For example if a gas heated in a rigid container: the pressure and temperature </span>
<span>of the gas will increase, but the volume will remain the same. </span>
<span>This is called an isochoric thermodynamic process. </span>
<span>It is actually possible to do work on a system without changing the </span>
<span>volume, as in the case of stirring a liquid</span>
i think it depends on the speed rate
It's Z.
Without any force acting on it an object travels in a straight line.
In order to bend away from a straight line the object needs a force acting on it.
In order to move along a circle, the force on the object points toward the center of the circle. It's called the centripetal force.
Since the object's direction is changing it has acceleration.
The acceleration points toward the center of the circle.
