the figure shows the pv diagram of a heat engine. during which stage or stages are the following events

more than, less

less than, more

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

magnets not strong enough
