What does the slope ut the acceleration us net foree represent? a. b G/Mass of the system weight of the system Mass of the system Tension in the system 9. if the net force of the system is held corstant, which of the following graphs below shows the resulting

Explanation / Answer

Force (F) = mass (m) x acceleration (a)

1) if the mass of the cart is increased then acceleration will decrease so B is the correct answer.

2) if the force is increased then acceleration will also increase so A is the correct answer.

3) both the mass of the cart and force are doublem then there will not be any chang ein the acceleration so D is the correct answer.

4) the component of F is driving the block so it's acceleration will decrease so B is the correct answer.

5) then gravity will be opposing the motion so the acceleration will decrease so B is the correct answer.

6) since total mass of th system is same so acceleration will also be same so option C is correct.

7) from F = ma

If mass is kept constant the force is directly proportional to the acceleration.

So straight line will come. So option B is correct.

8) slope will represent the mass of the system.

9) ma = constant

So graph will be rectangular hyperbola.

So option D is correct.
