The specific heat of water is 4186 J/kg•K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.0 g/cm.
A 3-kg block is suspended by a spring and is at rest on the floor. The spring has a spring constant k equal to 360 kg/s2. what is the unstretched length of the spring
You have a great summer job working in a cancer research laboratory. Your team is trying to construct a gas laser that will give off light of an energy that will pass by the skin but be absorbed by cancer tissue.
For the process where wk(closedsystem)=778 ft*lbf/lbm and ?u= 0.75 Btu/lbm, determine the heat transferred per pound mass
A 4.40 kg ball is dropped from a height of 14.0m above one end of a uniform bar that pivots at its center. The bar has mass 7.50kg, How high will the other ball go after collision
In the figure, block 2 (mass 1.10 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 231 N/m. by what distance is the spring compressed
A ball with a horizontal speed of 1.25m/s rolls off a bench 1.00m/s above the floor. how long does it take to reach the floor.How far from a point on the floor directly below the edge of the bench would the ball land.
A Force F= (6xi+ 5yj), where F is in newtons and x and y are in meters, acts on an object as the object moves in the x direction, Find the work W = integral (F · d vector r) done by the force on the object
If the coefficient of friction between the book and the wall is .35, explain how hard would she have to push in order to allow the book to slide down at constant speed?
