A 10g ice cube, initially at 0 C, is melted in 100g of water that was initially 20 C. After the ice has melted, the equilibrium temperature is 10.93 C a. The total heat lost by the water (the specific heat for water is 4.186J/g/K

If a simple machine reduces the strength of a force, what must be increased?

What is the equation for electrical work?

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
