Se consideran dos cargas q1 y q2, situadas como muestran la figura. Si q2 es negativa y q1 es positiva, la dirección del campo eléctrico en A es:

Arock is dropped from a cliff and reaches the ground in 2.70s. at the same time another rock is thrown horizontally from the same height with initial x velocity of 0.95 m/s. what distance will in x will the second rock cover?

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.
