Help. A person pushes a giant boulder with a force of 50N for 10min. The boulder moves 0cm. Use what you know about force, work, and acceleration to explain what happened.

Question 33 options:

500J of work was done because the person pushed for 10 min

The boulder moved 10m because the person pushed for 10 min

The person did a lot of work because s/he pushed with a high force

No work was done because the boulder was not displaced

i wish i could with all of them i can barley see the first one so here's the answer to the first one b

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
