A diver on Earth (where the atmospheric pressure is 1.00 atm and the acceleration due to gravity is 9.80 ms-2) descends in salty sea water with a density of 1027 kgm-3. The diver is holding a balloon close to him and the volume of the balloon is V at the surface of water is 2.53 × 10-3 m3.
1. What pressure does the diver experience at a depth of 17 m?
2. What is the volume of the balloon at this depth? Make the assumption that the temperature inside the balloon has not changed.
3. The diver can survive a pressure of 44 atm when wearing very specialized equipment. What is the maximum depth that the diver can descend to?
A 22cm diameter cylinder that is 12cm long contains 30 g of oxygen gas at 21 degrees C. What is the reading of a pressure gauge attached to the tank
Consider two masses m1 and m2 at the top of two frictionless inclined planes. Both masses start from rest at the same height. However, the plane on which m1 site is at an angle of 30 degrees with the horizontal,
A 25 kilogram kid on a play ground swing moves with a speed of 4.5 m/s when the 3.0 meter long swing is at its lowest point. Find the angle that the swing makes with the vertical when the kid is at the highest point
An LC circuit with a 4.60 pF capacitor oscillates in such a manner as to radiate at a wavelength of 3.40 m. What inductance is in series with the capacitor

A merry-go-round is 11m in diameter. The outermost horses are set at a diameter of 10m. If the merry-go-round spins at 2 RPM what is the tangential speed of the outermost horses?
A gun is fired vertically into a 1.9 kg block of wood at rest directly above it. If the bullet has a mass of 21.00 g and a speed of 195 m/s, how high would the block rise into the air after the bullet becomes embedded in it.
A 23 kg body is moving in the direction of the positive x axis with a speed of 292 m/s when, owing to an internal explosion, it breaks into three pieces.
