Two 5.0-kg carts collide on a one-dimensional air track. The total momentum of the carts was 4.9 kg m/s rightwards before the collision. After the collision, one cart is moving leftwards at 0.15 m/s. what is the velocity of the second cart?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

What causes the formation of ocean currents?

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
