I'll give you a crown if it's right. What is the force of gravity between two objects each with a mass of 7.75x 106kg separated by 2 m. (G=6.67 x 10-11)
Group of answer choices
2340.8 N
1001.5 N
3120.4 N
2100.4 N

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
