A student conducts an experiement in their class. They determine that when you increase a mass by four times it's original amount, the acceleration is experiences also drops to 1/4th of it's original value. What value was the student holding constant during this experiment? a Force b Mass c Acceleration d Weight

Correct answer is A  Force

Explanation:

The experiment that the students are carrying out is to verify Noten's second law, which has the equation

         F = m a

where F is the force, the acceleration and m the mass of the body.

In this case, they indicate that slats were increased 4 times and the acceleration decreased 4 times, therefore when replacing

         F = (4m) (a/4)

from here we can see that the force remains constant.

Correct answer is A

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
