Ocean Currents: List two ways currents affect life on earth.

A boy of mass 60 kg stands on a boat of mass 250 kg. This system is stationary. From the boat, the boy throws a rock of mass 1 kg into the water with a velocity of 10 m/s.

An ideal gas is held in a canister of volume V, at pressure P, and temperature T. Subsequently, the movement of a piston doubles the volume (to 2 V), while the temperature is also doubled (to 2 T), in absolute units (e. g. Kelvin).

Ultrasound. High-frequency sound waves (ultrasound) are used to probe the interior of the body, much as x rays do. To detect a small objects such as tumors, a frequency of around 5.10 MHz is used.
