In the diagram, q1= -2.00 x 10-5 C, q2= +3.80 x 10-6 C, and q3= +5.30 x 10-5 C. What is the electric potential energy Ue for charge q2? Include the correct sign (+ or -)

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
