The diagram shows a beam lying on the ground. End Q is lifted from the ground by the force F. End P of the beam remains on the ground. 3.0 m 1.0m P Р G ground beam The length of the beam is 3.0m and its weight is 600 N. The centre of mass of the beam at G is 1.0 m from end P. What is the size of the force when it just raises end Q from the ground. ​

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.

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.
