When 2 forces are applied in opposite directions, how do you calculate the net force?

a. you find the net force by dividing

b. you find the net force by subtracting

c. you find the net force by adding

d. you find the net force by multiplying

real, smaller and upside-down.   so the answer should be b.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

moisture is lackin, and organic acids are scarce.
