During the time 0.26 mol of an ideal gas undergoes isothermal expansion at 558 K, 293 J of work is done by it on its surroundings. If the inital volume is 2.7 m3, what is the final volume? (in m3)
A .2 kilogram stone is attached to a string and swung in circular motion with radius of .6 m on a horizontal and frictionless surface. find the tension on the string attached to the stone
A wheel starts at rest and takes 3.00 s to rotate 37.0 revolutions at which point its angular velocity is 98.0 rad/s. What is the constant angular acceleration of the wheel
A monatomic ideal gas expands at constant pressure. (a) What percentage of the heat being supplied to the gas is used to increase the internal energy of the gas? (b) What percentage is used for doing the work of expansion?
A hockey puck is given an initial speed of 5.4m/s. how far does the puck slide before coming to rest
I put a packing peanut on top of it, and it only took one rotation--or crank--to knock the material off from the machine and onto the ground. mass of the peanut=.001 kg, distance from the machine to the peanut=.0005m.
Two 3.0kg masses are 1.0m apart on a frictionless table. Each has 1.0C of charge. What is the magnitude of the electric force on one of the masses? What is the initial acceleration of every mass if they are released and allowed to move?
An 8.56-kg block slides with an initial speed of 1.80 m/s down a ramp inclined at an angle of 27.4° with the horizontal. compute the distance the block slides before coming to rest
A square coil of wire with a single turn is placed perpendicular in a uniform 1.0T magnetic field. Each side has a length of 0.5m. The current through the coil is 20A. Determine the magnitude and direction of the magnetic force on each of the four si..
A car of mass 960 travels at a speed of 30 along the straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.88. Take the acceleration due to gravity to be 9.80..
