What is the impulse of a 1700 kg truck traveling at 22.5 m/s?

According to social exchange theory, altruistic behaviors benefit the individual who performs them.

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j

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