The angle between 3N and 4N is anywhere between 0' and 90. which value of R is not possible? and how?

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

it has to be b, about 97 percent.
