The correctly balanced equation for H 2O 2 → H 2O + O 2 is

Which of the following statements is true? All work gains some energy as heat. Radiation is the transfer of heat in solids. An insulator speeds up the transfer of heat. All moving objects experience friction.

Which statements correctly describe forces? Check all that apply. Forces have the ability to change an object's state of motion. Forces are vectors. Forces are measured in joules. Forces are measured in newtons.

If the distance between slits on a diffraction grating is 0.50 mm and one of the angles of diffraction is 0.25°, how large is the path difference?

If 600 j of work is done in 3 s, what is the power? (power: p = w/t) 0.005 w200 w603 w1800 w

Calculate how much work is done if a current of 2A flows through a potential difference of 12V for 2 minutes

How do you distinguish between speed, velocity, and acceleration?
