Two horizontal forces are exerted on a large crate. the first force is 317 n to the right. the second force is 173 n to the left a. draw a force diagram for the horizontal forces acting on the crate. b. what is the net force acting on the crate? c. the box is initially at rest. five seconds later, its velocity is 6.5 m/s to the right. what is the crate's mass?

Observations show that interstellar clouds can have almost any shape and

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
