Aplane drops a hamper of medical supplies from a height of 3250 m during a practice run over the ocean. the plane’s horizontal velocity was 129 m/s at the instant the hamper was dropped. what is the magnitude of the overall velocity of the hamper at the instant it strikes the surface of the ocean? the acceleration of gravity is 9.8 m/s 2 . answer in units of m/s.

The mini-refrigerator fire was most likely caused by what type of wiring?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

Asquare isothermal chip is of width w=5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at tinf=15 °c. from reliability considerations, the chip temperature must not exceed t=85 °c. if the coolant is air and the corresponding convection coefficient is h=200 w/m2 x k, what is the maximum allowable "power" of the chip? if the coolant is a liquid for which h=3000 w/m2 x k, what is the maximum allowable power of the chip?
