Your friends car has stalled in the road. You help you friend push the car off the road. Your friend pushed with a force of 55 N and you push in the same direction with a force of 60 N. How much force is being applied to the car

115N

Explanation:

your  friend and you push the car at the same time at the same direction so you add the force your friend is using and the force you’re using so: 60+55=115N

a is the answer to this question

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
