A) What's the net force acting on the sheep? b) The rooster on top weighs 2.1N. The cow's back pushes up with a force of 5.8 N. What's the magnitude of the weight of the sheep?
c) What's the mass of the sheep?

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

ok

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

i think its c if i'm wrong
