calculate the rate of loss of heat through a glass window of area 100cm^2 and thickness 1cm when tempeture inside is 30°C and outside is -5°C, coefficient of thermal conductivety of glass is 2.2×10^-3 cal s^-1 cm^-1 K^-1.

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
