Answer:
<h2>300 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 2 × 10 × 15
We have the final answer as
<h3>300 J</h3>
Hope this helps you
The wavelength decreases to roughly half.
(The frequency roughly doubles.)
Well lets see, an ocean drying up is one, or another is that an earth quake flattened it. If this is an a b c or d question can I see the possible answers?
Explanation:
Radiation biology is the study of the effects of ionizing radiation on living organisms, when this radiation is absorbed in biologic material, ionization and excitations occur in a pattern that depends on the type of radiation involved, considering how far the primary ionization events are separated in space, radiation can be sparsely ionizing (for example, an x-ray or a gamma-ray) or densely ionizing (for example, a proton or an alpha particles).
<em>DNA is the most critical biological target because of the limited redundancy of the genetic information it contains, most lesions are reparable, but those produced by densely ionizing radiation are generally less reparable than those produced by sparsely ionizing radiation. Densely ionizing (high LET) radiations, therefore, typically have a higher relative biological effectiveness.</em>
I hope you find this information useful and interesting! Good luck!
