Asmall bubble rises from the bottom of a lake, where the temperature and pressure are 4°c and 3.0 atm, to the water's surface, where the temperature is 25°c and the pressure is 0.95 atm. calculate the final volume of the bubble if its initial volume was 2.1 ml.

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.

Which body is in equilibrium? (1) a satellite orbiting earth in a circular orbit (2) a ball falling freely toward the surface of earth (3) a car moving with a constant speed along a straight, level road (4) a projectile at the highest point in its trajectory

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
