Newton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass m on a body of mass M is F =    GmM/r2 where G is the gravitational constant and r is the distance between the bodies. (a) Find dF/dr.         What is the meaning of dF/dr? dF/dr represents the rate of change of the force with respect to the distance between the bodies. dF/dr represents the rate of change of the mass with respect to the distance between the bodies.     dF/dr represents the rate of change of the distance between the bodies with respect to the force. dF/dr represents the rate of change of the mass with respect to the force. dF/dr represents the amount of force per distance. What does the minus sign indicate? The minus sign indicates that the force between the bodies is decreasing. The minus sign indicates that as the distance between the bodies increases, the magnitude of the force decreases.     The minus sign indicates that as the distance between the bodies decreases, the…
Calculate the mass in kilograms of a 1.77 kg object when its velocity, relative to us, is each of the following values. (Notice the progression of these numbers toward the velocity of light, 3.00× 10° m s1) velocity = 3.07 x 107 ms1 m = i kg velocity = 2.75 × 10° ms1 kg m = i velocity = 2.98 x 10°ms1 kg m =
at rest and his mass is 50 kg, how fast is he moving 5. Einstein walks into an elevator cab and steps on a scale. If Einstein's mass is 62.0 kg, what does the scale read while the cab is accelerating upward at 3.20 m/s²?
