A boxed 15.0kg computer monitor is dragged by friction 5.50m up along the moving surface of a conveyor belt inclined at an angle of 36.2 degrees above the horizontal. If the monitor's speed is a constant 2.20cm/s , how much work is done on the monitor by friction, gravity, and the normal force of the conveyor belt?

a) W friction = J

b) W gravity = J

c) W N = J

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

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.
