Answer:
There is no change, unless your mass is somehow at the quantum level, at which the concept of half-life breaks down.
Half life is a property of the specific radioactive isotope...NOT of the initial sample's mass.
For this problem, we will need the famous equation F=ma, as detailed by Isaac Newton.
F=mass x acceleration, where Force is in Newtons.
20 m/s represents the quantity of speed change, but to use in the equation, we need acceleration, not speed. Acceleration is the velocity change over a unit time, so changing 20 m/s in 0.1 seconds means that the acceleration was 200 m/s^2.
Plugging in all your numbers, you find:
F=(0.45 kg)(200 m/s^2) = 90 N of force.
The sun is 1.989E30 kg. <em>It's radius is 695, 800 Km.</em>
Answer: 42g
Mass will still stay the same because mass is a weight without pull of gravitational force. So whichever plant it is in, even in jupiter, the mass is going to be 42g.
The answer is: To have easy access to a coolant for the reactor.
Hope this helps!:)
