Both gravitational and electric field obey inverse square laws (e.g. F(grav)=GMm/r^2 and F(electric)=kq1q2/r^2 where GMm and kq1q2 are constants). They both act between two bodies without any means of con...
In the Young double slit experiment, coherent light of wavelength λ from a single source illuminates a system of two slits separated from each other by a small distance a. Each slit causes the light enter...
75g = 0.075kg/ 37.5cm3 = (37.5 divided by 1003) m3 = 3.7510-5m3/ density = mass divided by volume/ 0.075 divided by 3.7510-5 = 20...
slows neutrons/reduces KE of neutrons so that neutrons can be absorbed by the U-235 nucleus to cause fission to release kinetic energy. (nuclear reactor and energy)
Since we want to find the height reached by the ball, we only want to consider the vertical component of the ball's velocity. Using trigonometry, the y component will be:vy= 15 * sin (45)...
