An airtight freezer holds n moles of air at 27.3°C and 1.00 atm. The air is then cooled to -20.7°C.
(a) What is the change in entropy of the air if the volume is held constant?
(b) What would the entropy change be if the pressure were maintained at 1.00 atm during the cooling?
A 1,262-kilogram roller coaster car starts at point A almost at rest. It runs downhill into a valley. At its bottom, the valey can be described by a circle with radius 12 m. Find the height required at point A, such that the normal force acting on ..
A 42-kg girl is standing on a 125-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. What is her velocity relative to the ice surface
A puck of mass m1 = 63g and radius r1 = 4.30 cm glides across an air table at a speed of = 1.50 m/s. It makes a glancing collision with a second puck of radius r2 = 6.00 cm and mass m2 = 115 g (initially at rest) such that their rims just touch.
A 0.410 kilogram pendulum bob passes through the lowest part of its path at a speed of 3.00 m/s. Find the tension in the pendulum cable at this point if the pendulum is 80.0 centimeter long
A 245 ball is tied to a string. It is pulled to an angle of 5.20 and released to swing as a pendulum. A student with a stopwatch finds that 10 oscillations take 10.5.
Three forces are applied to an object. Force F1 has a magnitude of 20.3 newtons (20.3 N) and is directed 30.0° to the left of the +y axis.
How much energy has been stored in the magnetic field of the inductor during the first 2.100 s after the switch has been closed? At what rate is thermal energy being produced in the resistor at time t = 1.050 s?
