Answer:
Rate at which energy is being removed by the heat = 89.625 watts
Explanation:
P = (c₁m₁ + c₂m₂)ΔTₓ
Where P = rate at which energy is being removed by the heat, c₁ = specific heat capacity of water, m₁ = mass of water, c₂ = specific heat capacity of aluminium, m₁ = mass of aluminum, ΔTₓ = rate of temperature decrease.
Where c₂ = 900 J/kgK, m₁ = 800 g = 0.8 kg, m₂ = 250 g = 0.25 kg, c₁ = 4200 J/kgK, ΔTₓ = 1.5°C per minute
P =( 4200×0.8 + 900× 0.25)1.5
P = (3360 + 225 ) 1.5
P = (3585 )1.5
P = 5377.5 J/ min.
P = 5377.5/60 = 89.625 watts.
Rate at which energy is being removed by the heat = 89.625 watts
P = m x v
P = 30 x 10
=300
Playing in a team helps children to develop many of the social skills they will need for life. It teaches them to cooperate, to be less selfish, and to listen to other children. It also gives children a sense of belonging. It helps them make new friends and builds their social circle outside school.
