An x-ray tube emits x-rays with a wavelength of 1.00 x 10-11 m. calculate the photon energy, in joules, that the emitted x-rays possess. e = x 10 joules

Why does the input force have to be greater than the force needed to lift the bale?

Atotal charge of –6.50 µc is uniformly distributed within a sphere that has a radius of 0.150 m. what is the magnitude and direction of the electric field at 0.300 m from the surface of the sphere? a) 2.89 × 105 n/c, radially inward b) 6.49 × 105 n/c, radially outward c) 4.69 × 105 n/c, radially inward d) 9.38 × 105 n/c, radially outward e) 1.30 × 106 n/c, radially inward

Is the number of complete movements of a wave per second.
