Protons having a kinetic energy of 4.70 MeV are moving in the positive x-direction and enter a magnetic field of 0.0650 T in the z-direction, out of the plane of the page, and extending from x = 0 to x = 1.00 m. Required:
Calculate the y component of the proton%u2019s momentum as they leave the magnetic field.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

This is the substance(s) formed in a chemical reaction.
