My notes of the charge q initially on a tiny sphere, a portion q is to be transferred to a second, nearby sphere. both spheres can be treated as particles and are fixed with a certain separation. for what value of q/q will the electrostatic force between the two spheres be maximized?

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

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.

Distinguish between linear momentum and angular momentum
