The answer should be B. a stable isotope to a decaying isotope.
Answer: 1.2m/s^2
Explanation: the force exerted on the car is 900N upwards
The mass of the car is 750kg
According to Newton's third law acceleration is proportional to force
F = ma
900 = 750a
a = 900/750
a = 1.2m/s^2
Centripital acceleration. When an object moves in a circle, centripital acceleration acts to accelerate the object towards the center of that circle
Electron as a free particle
Explanation:
Free electrons,the electrons which are not attached to the nucleus of a atom and free to move
