What is the result of mixing 100g of ice at 0°C and 100g of water at 100°C? Latent heat of fusion of ice = 3.36x105 g/k, specific heat of water= 42005 kg/k.

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
