An ideal gas is allowed to expand slowly at constant temperature to twice its original volume. Through the expansion, 200 kJ of heat is absorbed.
a) How much work does the gas do during the expansion?
b) What is the change in the gas's thermal energy during the expansion?
A rescue plane wants to drop supplies to isolated mountain climbers on a rocky ridge 235 m below if the plane is traveling horizontally by a speed of 250 km / h (a) how far in advance of the recipients should the goods be dropped
A person pulls a toboggan for a distance of 41.7 m along the snow with a rope directed 24.3 ° above the snow, How much work is done on the toboggan by the tension force
A pair of slits, separated by 0.170 mm, is illuminated by light having a wavelength of ? = 624 nm. What is the path difference for the two slits at the location y
A wire carries a current of 6.0 A in a direction that makes an angle of 36.0° with the direction of a magnetic field of strength 0.300 T. Compute the magnetic force on a 7.00-m length of the wire.
Assume we have an infinitely long wire carrying a current of 2.50 A. It is bent into an L-shape extending into positive infinities along x- and y- axes. Find out the magnitude of the magnetic field at a point P with coordinates (0.30 m, 0.30 m)
The potential at location A is 478 V. A positively charged particle is released there from rest and arrives at location B with a speed vB, Find the potential at B
