What is the momentum of a 12,000 kg car moving at a speed of 40 m/s?

Lithium is a metal with an oxidation number of 1 + and oxygen is a nonmetal with an oxidation number of 2-. Which chemical formula represents the compound formed by these two elements?

1. A ball bouncing against the ground and rebounding is an example of an elastic collision. Describe two different methods of evaluating this interaction, one for which momentum is conserved, and one for which momentum is not conserved.

What substance resist pH change?

How could a lightbulb near an electromagnet, but not touching it, be lit? Is ac or dc required? Defend your answer.

A 75 kg ball carrier is running to the right at 6.5 m/s. An 80 kg defender is chasing the ball carrier running at 7.0 m/s. The defender catches the ball carrier in a completely inelastic collision.

A transfer by work from the system, an elevation decrease of 50 m, and an increase in velocity from 15 m/s to 30 m/s. The specific internal energy, u, decreases by 5 kJ/kg and the acceleration of gravity is constant at 9.7 m/s².

What is the best prediction for the weather on the day after high pressure system passes

Is it possible to have motion in the absence of a net force?

There are 2 charged particles, A and B. You know that particle A is positively charged. When you place particle B next to particle A, then particle B starts moving away from particle A. What does this mean for particle B?

The speed of light is now to be defined 2.99792458x10^8 m/s express the speed of light to three significant figures five significant figures seven significant figures
