A sledder begins from rest on an incline at a location near the top of a small hill (initial state) and slides effortlessly to ground level at the bottom of the hill (final state). Assume negligible friction and air resistance.

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5

The sun's gravitational pull is weaker on the planets that are closer to it, i think.

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

From my calculation, i got 3.655moles
