Meghan and Kailey are attempting to push a piano down the hallway, but as they turn up the 8thgrade hallway they are faced with

a hill. Meghan and Kailey are pushing with a force of 10N each, but the heavy piano is exerting a force of 50N in the opposite direction. Will the girls be able to push the piano? What happens if two other students begin to help by pulling on the piano. Danny pulls with a force of 17N and Liam pulls with a force of 16N. How much force is being exerted on the piano, and will the piano move?

Meghan and Kailey make a pushing force of 20 newtons together, so no they will not push the piano. However with Danny and Liam they make a total force of 53 Newtons so they should be able to push it up the hill.

How much energy must be absorbed by water with a mass of 0.5 kg in order to raise the temperature from 30°C to 65°C? Note: Water
kvasek [131]

Answer:

73325J

Explanation:

Given parameters:

Mass of water  = 0.5kg

Initial temperature  = 30°C

Final temperature  = 65°C

Specific heat capacity  = 4190J/kg°C

Unknown:

Amount of energy absorbed = ?

Solution:

The amount of energy absorbed can be derived using the expression below;

                H  = m c Δt

H is the amount of energy

m is the mass

c is the specific heat

Δt is the change in temperature

      H  = 0.5 x 4190 x (65 - 30 )

     H  = 73325J
