Three blocks of metal at the same temperature are placed on a hot stove. their specific heat capacities are listed below. rank them from greatest to least in how quickly each warms up. steel, 450 j/(kg⋅∘c) aluminum, 910 j/(kg⋅∘c) copper, 390 j/(kg⋅∘c)

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Could someone . i have tried to solve myself but my calculation is off
