Two students both kick a soccer ball. Havanna's ball travels three times as fast as Mitzi's ball. How does the kinetic energy of the two soccer balls compare? A. Both soccer balls have the same amount of kinetic energy, because they have the same mass. B. Mitzi's soccer ball has 3 times as much kinetic energy, because it travels a third of the speed. C. Havanna's soccer ball has 9 times the kinetic energy, because it travels at 3 times the speed. D. Havanna's soccer ball has 3 times because it travels at 3 times the speed.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

How is zig zagging a form of acceleration?

Is the portion of the electromagnetic spectrum that has a frequency just above that of visible light.
