Pour into a container with a longitudinal expansion coefficient of five times ten to the negative power of five, a liquid with a longitudinal expansion coefficient of three to fifty-five hundredths multiplied by ten to the negative power of four. Increase the temperature of the set by a few degrees Kelvin to increase the height of the liquid inside the container by five percent? (Liquid does not spill out of the container)

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?
