Just 2 questions I need help on, may you please help a girl out it’s due today .. 1. A student did 24 J of work on a chair. He applied a force of 12N and moved the chair 2m. What else do you need to know to determine how much power was used ?

2. Calculate what force was applied to an object if 35 J of work was done and the object moved 7m? Force = work + distance = show your work.

the answer is   c.) 1575 j.

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
