With the temperature held constant, the pressure of a gas in a cylinder with a movable piston is increased from 18 kPa to 40 kPa. The initial volume of the gas in the cylinder is 0.75 m^3. What is the final volume of the gas after the pressure is increased?

If steel is more dense that lake water, why can a boat float

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
