I'm pretty sure it means like getting abs and working out your stomach.
Explanation:
Answer:
Potential Energy = 294J, Kinetic Engergy = 48.02J
Explanation:
We have these formulas:
Potential Energy = mass * gravitational force * height (m) = 1 * 9.8 * 30 = 294(J)
Kinetic Energy = 1/2 * mass * velocity^2 = 1/2 * 1 * 9.8^2 = 48.02 (J)
As the rock falling at an acceleration of 9.8m/s^2 which means for each second, the rock increases 9.8m/s. I think we are missing time to find the instantaneous velocity, the formula is (initial displacement - final displacement)/ (initial time - final time) which will directly give the final answer for you.
Radioactive isotopes of an atom aren't as stable as you would think, so the correct answer is: C. Less Stable
(I can verify this because I took the test.)
Hope this helps! Have a wonderfully wonderful day!
Cheers mate!
The mass of the iceberg is 71.9 kg
Explanation:
The amount of thermal energy needed to completely melt a substance at its melting point is given by
where
is the latent heat of fusion
m is the mass of the substance
In this problem, we have a block of ice at its melting point (zero degrees). The amount of heat given to the block is
And the latent heat of fusion of ice is
So, we can re-arrange the equation to find m, the amount of ice that will melt:
