It is proposed to have a water heater that consists of an insulated pipe of 5-cm diameter and an electric resistor inside. cold water at 20°c enters the heating section steadily at a rate of 30 l/min. if water is to be heated to 55°c, determine (a) the power rating of the resistance heater (b) the average velocity of the water in the pipe.

What are the theoretical properties of a gas at a temperature of 0 kelvin?

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
