You have a system of two objects, both of which are 1kg. One moves with a velocity of 5 m/s in the positive y-direction. The second moves with a velocity of 3 m/s in the positive y-direction. What is the magnitude of the total momentum of the system (assume Sl units)? a) 5 b) 2 c) a number greater than 5 but less than 8 d) a number less than 5 but greater than 3e) 3f) 8

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths

Which statements identify what astronomers currently know and think will happen with our universe? check all that apply. the big bang produced dark energy, which accounts for some of the energy needed to expand the universe. the vastness of space may contain a type of matter known as "dark matter." the universe is currently shrinking at a rapid rate. the universe is currently expanding at an accelerating rate. the big bang theory explains all the energy and matter discovered by scientists.
