We all know that there are 365 days in a year, 24 hours in a day, 60 minutes in an hour and lastly 60 seconds in a minute. Round that off to 100, 10, 100 and 100.That will be 10^2 x 10^2 x 10^1 x 10^2 = 10^7 seconds.

➷ After 10,000 years the mass will be:
1,000 / 2 = 500
After 20,000 years the mass will be:
500/2 = 250
As you can see, the correct answer would be A. 20,000 years

200 ms² is the kinetic energy for an object that weighs 40g and moving at 10 m/s.
<h3>What are kinetic energy ?</h3>
Kinetic energy is the power that an object has had as a result of motion. To accelerate an object, a power must be supplied to it. To apply a force, we must exert effort. The power is transported to the object when work is accomplished, which causes it to move at a new, constant pace.
<h3>What makes kinetic energy so important?</h3>
The capacity to perform work is unquestionably the most important characteristic of kinetic energy. Force acting on to an object while it is traveling is referred to as work. Energy and work are interchangeable because of their close relationship.
<h3>Briefing:</h3>
Using Kinetic Energy Formula:
K.E = 1/2 mv²
K.E. = 1/2 * 40 * 10
K.E. = 200 ms²
