In the isentropic coordinate system (see section 4.6), potential temperature is used as the vertical coordinate. because potential temperature in adiabatic flow is conserved following the motion, isentropic coordinates are useful for tracing the actual paths of travel of individual air parcels. show that the transformation of the horizontal pressure gradient force from z to θ coordinates is given by

none, its a machine

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
