A roller-coaster car has a mass of 1240 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 22 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative sign for the downward direction) FN on the car from the track if the car's speed is v = 8.7 m/s? (b) What is FN if v = 20 m/s? Use g=9.81 m/s2.

A storage tank has the shape of an inverted circular cone with height 15 m and base radius of 5 m. It is filled with water to a height of 11 m. Find the work required to empty the tank by pumping all of the water to the top of the tank. (The density of water is 1000 kg/m3. Assume g = 9.8 m/s2 is the acceleration due to gravity. Round your answer to the nearest integer.) g

Why is ultraviolet radiation considered more dangerous to humans than infrared radiation?ANSWER:Ultraviolet radiation has a shorter wavelength than infrared radiation, and thus, the waves have higher energy. This allows them to penetrate the first layers of skin on humans and can mutate the DNA in the cells of the skin. This can result in cancer because of the mutations caused by the ultraviolet radiation.
