Best answer gets brainliest! 1) Which two of the following factors affect the momentum of an object: speed, velocity, mass, shape?

2) Can a small object can have a large momentum? Give an example.

3) How could you change the momentum of an object? What would you need to change?

4) A 5000kg truck and a 50 kg person have the same momentum. How is this possible?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
