"Its mass stays the same, and it becomes a different element" happens if an atom loses a neutron.

Option: D

Explanation:

Neutrons have a neutral charge, and are component of the nucleus, which means they contribute mass / weight ultimately to the atom. If you were to remove one of these, It would be the same aspect. Elements are clearly described by their protons and not by neutrons.

Neutrons do not carry an electrical charge and adding or removing it from the nucleus does not alter the nucleus' electrical charge. However it affects the nucleus mass. This isotopes are produced is the addition of or removal of neutrons from the nucleus.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

Velocity is the speed of an object in a certain direction so you'd need to know speed and direction
