Study the image of two people pushing on opposing sides of a dog house at the same time. Compute the amount of force acting on the doghouse using the vector addition rule. O 20 N, the doghouse remains at rest
O 0N, the doghouse starts moving in one direction and then slows to a stop.
O 0N, the doghouse remains at rest.
O 70 N, the doghouse remains at rest.​

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.
