A chain lying on the ground is 10 m long and its mass is 70 kg. How much work (in j) is required to raise one end of the chain to a height of 4 m? (use 9. 8 m/s2 for g. ).

With any turning vehicle, the rear wheels follow a shorter path than the front wheels. the longer the vehicle is, the greater the difference will be. truck drivers initially swing out before making a turn. what isn't shown in this illustration is as car straightens out, the front wheels must travel a greater distance and the tail end drags on the shortest path.

    the box has volume x^2h.  the cylinder has volume x^2h/4.  v = πr^2h = x^2h/4  πr^2 = x^2/4  r^2 = x^2/(4π)  r = x/(2√π)  b

Only one apple is left

Their are less so maybe the bathroom
