Which statement is true because of Newton's second law? When the net force on an object decreases, the object's acceleration increases.

When the net force on an object decreases, the acceleration doesn't change.

When the net force on an object increases, the object's acceleration decreases.

When the net force on an object decreases, the object's acceleration decreases.

when the net force of an object decreases

, the objects acceleration decreases.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
