Dos placas metálicas se mantienen unidas por 5 remaches de aluminio de 0,600 cm de diámetro. Si las placas ejercen una fuerza total de 208 kN que se distribuye equitativamente, calcule el ángulo de inclinación que sufrirá cada remache.
a)1,26º
b)0,38º
c)0,06º
d)3,37º

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

Substances that assume the shape of their container, but do not have a definite size are called

Car batteries are often rated in amp-hours. this rating indicates the quantity of charge that can pass through the battery before the battery's chemical energy must be restored by the car's generator or some other source. the amp-hour unit is convenient for simple calculations. for example, a 60-amp-hour battery can supply a current of 1.0 a for 60 h (or 60 a for 1.0 h) before going dead. find the energy stored in the following. (a) a 58 a-h, 10 v car battery(b) a 1.3 a-h, 1.7 v flashlight battery
