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

atomic = no of protons.

mass number-atomic number = neutron number
