Explanation:
2. Heat gained by tap1 = mass1 × SHC × change in temperature
= mass1 × 4200 × (40 - 26)
= mass1 × 58800
Heat lost by tap 2 = mass2 × SHC × change in temperature
= mass2 × 4200 × (82 - 40)
= mass2 × 176400
Heat gained = heat lost
mass1 × 58800 = mass2 × 176400
Ratio of mass 1 to mass 2 = 58800mass1 : 176400mass2
= 1 : 3
Answer:
No, they are not because when you stretch the rubber band you are deforming it but with the spring it is made to go up and down.
Explanation:
Answer:
They're are useful in providing larger frictional force

The studs helps to prevent a player from slipping on the grass and help to run faster and change direction quickly without slipping.
