The isotope of uranium suitable for nuclear fission in a power station is uranium-235, but in natural uranium only 0.711% is U-235, the rest is U-238. How much U-235 could be extracted from 32.3 kg of natural uranium?

What mass will a pumpkin have a force of 450 newton’s accelerates it to 110 m/s^2? include the correct units.

Amira pulls a 3 pound wagon 4 feet. how much work has she done?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
