A ladder of length 10 is leaning against a wall. The vertical wall is frictionless while the horizontal surface is rough. The angle between the ladder and the horizontal surface is 50 degrees. If the mass of the ladder is 14 kg, what is the magnitude of the friction force (in N) exerted on the ladder in the point of contact with the horizontal surface

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
