Answer:
Volume strain is 0.02
Explanation:
Volume strain is defined as the change in volume to the original volume.
It is given that,
Initial volume of the plastic box is 2 m³
It is then submerged below the surface of a liquid and its volume decreases to 1.96 m³
We need to find the volume strain on the box. It is defined as the change in volume divided by the original volume. So,
So, the volume strain on the box is 0.02.
normal force=mass*gravitational force
normal force=40*0
normal force=40
Answer: ice float in water due to density differences. Water has a higher density than ice.less dense object in liquid with high density
Explanation: from density formulae.
D=M/V
Density of ice =Mass of ice/Volume of ice
D=23/25
D=0.92g/cm^3
<span>if we take ball then the Kinetic Energy of the ball is ½mV²
as it rolls up the slope, the Kinetic Energy is converted to potential energy, PE = mgh.
mgh = ½mV²
h = V²/2g</span>
