Some hydrogen gas is enclosed within a chamber being held at 200^\ { C} with a volume of 0.025 \rm m^3. The chamber is fitted with a movable piston. Initially, the pressure in the gas is 1.50 \times 10^6 \; \rm Pa (14.8 \rm atm). The piston is slowly extracted until the pressure in the gas falls to 0.950 \times 10^6 \; \rm Pa. What is the final volume V_2 of the container? Assume that no gas escapes and that the temperature remains at 200^ { C}.
It's your birthday, and to celebrate you're going to make your first bungee jump. How far are you above the water when the cord reaches its maximum elongation
A light wave has a 670{\rm nm} wavelength in air. Its wavelength in a transparent solid is 420{\rm nm}. What is the light's frequency in the solid
The differential gear of a car axle allows the wheel on the left side of a car to rotate at a different angular speed than the wheel on the right side. A car is driving at a constant speed around a circular track on level ground, completing each l..
