HELP A car travels a displacement of 298 m North in a time of 12.7 s. Calculate the average velocity of the car. Include the correct unit and direction.

a. 0.043 m/s South

b. 0.043 m/s North

c. 23.5 m/s North

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

An object is 10. cm from the mirror, its height is 3.0 cm, and the focal length is 2.0 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1.33 -1.33 +0.75 -0.75

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?
