Explanation:
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
Answer:
- 0.328J
Explanation:
POTENTIAL ENERGY = mgh
= 0.00274 × 9.81×12.2 here 2.74g = 0.00274kg
= 0.32792868 J
= 0.328J
AS IT IS BELOW THE SURFACE HENCE MUST BE NEGATIVE
hence potential energy = - 0.328J
