Reduce the friction. Since the total energy is conserved, the only way to improve its work capacity is by reducing energy that doesnt go into work.
<span>So we want to know what is the change in isotopes over time due to the emission of radioactive particles. The radioactive decay is the process of emiting particles from the nucleus of the atom. The consequence is that the amount of the radioactive material is loosing its mass over time by emmiting energy or particles. It can be alpha particles- those are helium nucleus, beta particles- those are electrons and it can be gamma particles- those are high energy photons. So the correct answer is D, Radioactive decay.</span>

To answer this question, remember the formula ∆X = Vot + 1/2 at^2
To solve, all you have to do is plug in the numbers.
∆X = height of the ledge (the unknown)
t = time (8 seconds)
a = acceleration (9.8 m/s^2)
Vo = initial velocity
∆X = 0(8) + 1/2(9.8m/s^2)(8s)^2
∆X = 0 + 313.6 m
∆X = 313.6 meters
Your answer would be B, 313.6 meters
“It states that parts of the Earth's crust slowly drift atop a liquid core. The fossil record supports and gives credence to the theories of continental drift and plate tectonics. ... Continental Coastlines appearing to fit together,Fossil Distrubution, Distinctive Rock Strata, and Coal Distrubution.”
Hope this helps!
