9.00 mole of nitrogen (N2) gas and 9.00 mole of argon (Ar) gas are in separate, equal-sized, insulated containers at the same temperature. The containers are then connected and the gases (assumed ideal) allowed to mix. a) What is the change in entropy of the system?b) What is the change in entropy of environment?c) Repeat part A but assume one container is twice as large as the other.

b.

explanation:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

because if the tool that you are using is not balanced it there would be false mass.
