Agrindstone in the shape of solid disk with diameter 0.42 m and a mass of 50.0 kg is rotating at 750.0 rev/min. you press an axe against the rim with a normal force of 160 n and the grindstone comes to rest in 7.8 seconds. find the coefficient of kinetic friction between the axe and the grindstone. there is negligible friction in the bearings.
specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
double the distance = divide strength by 4
