A physicist uses a cylindrical metal can 0.300m high and 0.070m in diameter to store liquid helium at 4.22 K; at that temperature the heat of vaporization of helium is 2.09×104J/kg. Completely surrounding the metal can are walls maintained at the temperature of liquid nitrogen, 77.3 K, with vacuum between the can and the surrounding walls
How much helium is lost per hour? The emissivity of the metal can is 0.200. The only heat transfer between the metal can and the surrounding walls is by radiation.

In a classic clip on America's Funniest Home Videos, a sleeping cat rolls gently off the top of a warm TV set. (Ignore air resistance and consider upward motion to be positive with zero at the top of the TV).
A 4.5m long, non uniform beam weighing 750N, supported by two weighing cables, is at rest in horizonal position as shown . The cable on the right has a tension of T1=650 N.
