Dos Autos se acercan uno hacia el otro como se muestra en la figura. Si los carros chocan y quedan pegados, DETERMINE: a) las componentes de la velocidad después del choque.
b) La velocidad resultante después del choque,
c) El ángulo θ

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.

Which of these metals are magnetic?
