Q: the is the combination of all the forces acting on an object
answer choices:
a) direction of motion
b) force pair
c) net force
d) intertia

Hello :)

The answer would be (B)net force

The combination of all forces acting on an object is called the net force. Unbalanced forces acting on an object result in a net force and cause a change in the object’s motion. Balanced forces acting on an object do not change the object’s motion.

plz brainliest :'D

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
