You and your brother are pushing a car with a dead battery with forces of 20 N and 25 N in the same
direction. What is the resultant force applied on the
car?​

45 N

Explanation:

Add the forces together if they are going in the same directions.

20 N+25 N=45 N

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

b - the respond is innate and varies over time.

good luck!
