7.A 100,000kg rocket does not accelerate at 1m/s2 when a 100,000N of force is applied. Obviously, this refutes Newton’s 2nd law. Is this claim accurate or not? Explain.

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
