Two cars of different mass collide head-on in a demolition derby. Car A has twice the mass of car B. If car A exerts a maximum force of 1000 Newtons in the collision, what is the maximum possible force that car B exerts?
A 500 Newtons
B 1000 Newtons
C 2000 Newtons
D) 4000 Newtons

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

answer: they produce more slow than unicellular organisms.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
