An artificial satellite circles the Earth in a circular orbit at a location, Determine the orbital period of the satellite
In a nebula, the amount of interstellar extinction in the visible wavelength band is 1.1 magnitudes. The thickness of the nebula is estimated to be 16 pc and it is located 458 pc away.
Monochromatic light from a distant source is incident on a slit 0.750 {rm mm} wide. On a screen 2.00 {rm m} away, the distance from the central maximum of the diffraction pattern to the first least amount is measured to be 1.35 {rm mm}.
Three resistors, R1 = 17? , R2 = 52? , and R3=R, are connected in series with a 24.0 Vbattery, find the potential difference across each resistor
A skier with a mass of 59 kg starts from rest and skis down an icy (frictionless) slope that has a length of 44 m at an angle of 32° with respect to the horizontal.
