Write down an expression for the acceleration of a satellite of mass m in a circular orbit of radius R around the Earth. Use M for the mass of the Earth and G for the gravitational constant. Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³), square root (sqrt(a*b/c) for √√(a × b/c)) etc. a= Display response

The x and y coordinates of point P are (-8.50 m, -7.00 m). What is the magnitude of point P?

What is the magnitude, X (in m2), of the cross product of a vector of magnitude 7.2 m vector pointing east and a vector of magnitude 4.4 m pointing 25° west of north? Enter only the number, not the units below

Write down an expression for the velocity of a satellite of mass m in a circular orbit of radius R around the Earth. Take the mass of the Earth as M and use G for the gravitational constant.

I do not know how to get started with my graph. Does my x axis need to be between 7.84 or 15.68 and my y axis between 0.779 or 1.558. If so how should I start my graph and how much should I go up by with both x and y axis's. Please help! I am confused.

Schwarzschild radius RS of a black hole is the maximum distance from the black hole’s center at which light cannot escape its gravitational field. The quantity RS (with dimensions of length) is dependent on the mass of the black hole M, the speed of light c, and the gravitational constant G. Based on the dimensions of these four parameters, predict an equation for the Schwarzschild radius. Hint: G has dimensions of [L3/MT2]
