Heat is flowing through a slab of material by conduction heat transfer; and the heat flux is 16500W/m^2. If the slab is 3.0 cm thick and the thermal conductivity is 18 W /(m K), what is the temperature difference across the slab?

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

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.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
