Planetary ring systems can result from the destruction of a moon orbiting within the Roche limit of a planet. Choose the statement that best describes how a moon can be destroyed within this limit.
A. The moon is more likely to collide with other moons.
B. Tidal forces exceed the forces holding the moon together.
C. Atmospheric friction causes the moon to heat up and fracture.
D. Trapped particles from the solar wind can break up the moon

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.)

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
