His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.
Explanation:
Given that,
The disintegration constant of the nuclide,
(a) The half life of this nuclide is given by :
(b) The decay equation of any radioactive nuclide is given by :
Number of remaining sample in 4.44 half lives is :
So,
(c) Number of remaining sample in 14.6 days is :
So,
Hence, this is the required solution.
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
40 mi/h means miles per hour
Answer:
3 Cycles
Explanation:
Every cycle on a cosine function are marked by the completion of 5 key points when moving along the x-axis:
(5, 0, -5, 0, 5)
This cycle has a frequency of 2, occurring once every second, thus answering our question easily.
