When light illuminates a diffraction grating with 5424 lines per centimeter, its second order maximum is at 50°. What is the wavelength of the light in nanometers (nm)?

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

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
