The Answer is here
Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous, and just because nuclear pollution is invisible doesn't mean it's clean
In general? Well one example could be that if you owned an ice rink and somehow the ice had friction, you wouldn't be able to slide around on it any more to skate because the motion between one solid (your feet) and another (the ice) would increase. An effect of friction is heat, but my mixtape already fire so whats that even matter tbh.
Sound and thermal/ heat energy.
Explanation:
Electric drill use electrical energy to convert it into kinetic, but there are some energy waste during the conversion in the form of sound and thermal caused by electric motor.
Answer:
Explanation:
Given
N0 = 20kg (original substance)
decay constant λ = 0.179/sec
time t = 300s
We are to find N(t)
Using the formula;
n(t) = N0e^-λt
Substitute the given values
N(t) = 20e^-(0.179)(300)
N(t) = 20e^(-53.7)
N(t) = 20(4.7885)
N(t) =143.055
To know how much of the original material that is active, we will find N(t)/N0 = 143.055/20 = 7.152
About 7 times the original material is still radioactive
