Explanation:
Given that,
A ball is tossed straight up with an initial speed of 30 m/s
We need to find the height it will go and the time it takes in the air.
At its maximum height, its final speed, v = 0 and it will move under the action of gravity. Using equation of motion :
v = u +at
Here, a = -g
v = u -gt
i.e. u = gt
So, the time for upward motion is 3.06 seconds. It means that it will in air for 3.06×2 = 6.12 seconds
Let d is the maximum distance covered by it.
Putting all values
Hence, it will go to a height of 45.91 m and it will in the air for 6.12 seconds.
Answer:
microscopic means that they are very very tiny, you cannot see them with the human eye, you have to use a tool like a microscope

Answer:
11 ounces
Explanation:
The patient gets 11 ounces of liquid.
From the description of this problem:
Xavier administers four cups of liquid each containing two ounces
The number of ounces in the four cups = 2 x 4 = 8ounces
Also,
One cup of the liquid contains 3 ounces.
Total number of ounces administered = 8 + 3 = 11 ounces.

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>
