How much heat is required to convert 100.0 g of ice at -10.0°C to water at 50.0°C? the latent heat of fusion of water is 3.3x105 J/kg

the latent heat of vaporization of water is 2.3x106 J/kg

the specific heat of steam is 2.0 x 103 J/kg°C

the specific heat of water is 4.2 x 103 J/kg°C

the specific heat of ice is 2.1 x 103 J/kg°C

What equations are used to solve this?

Ten students stand in a circle and are told to make a transverse wave. what best describes the motion of the students? each student bumps the shoulder of his or her neighbor. at the exact time, all students take a step to the right. the students skip clockwise, going in a circular motion. one at a time, each student lifts his or her hands up and then down.

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
