In 1996, the Solar and Heliospheric Observatory (SOHO) was "parked" in an orbit slightly inside the earth's orbit. The satellite's period in this orbit is exactly one year, so it remains fixed relative to the earth. At this point, called a Lagrange point, the force from the sun and the force from the earth combine to give the satellite the same period of revolution as the earth. Calculate SOHO's distance from the earth. (Hint: You will need the binomial approximation. SOHO's distance from earth is very small compared to the earth's distance from the sun.)
A 50 kg projectile is fired over level land at an angle of 30 degrees above the horizontal with a muzzle velocity of 210 m/s. At the highest point in its trajectory it explodes into two fragments, one of twice as much mass as the other. The less m..
Two spherical shells have a common center. A -2.1 10-6 C charge is spread uniformly over the inner shell, which has a radius of 0.050 m. A +5.0 10-6 C charge is spread uniformly over the outer shell.
