4.003 is the mass of helium gas
The mass of the nuclide that will remain in the patient at 6:00 p.m. the next day is 94 g
<h3>How to determine the number of half-lives that has elapsed</h3>
We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:
- Half-life (t½) = 8 days = 8 × 24 = 192 hours
- Time (t) = 6 pm next day = 18 hours
- Number of half-lives (n) =?
n = t / t½
n = 18 / 192
n = 0.09375
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 100 g
- Number of half-lives (n) = 0.09375
- Amount remaining (N) = ?
N = N₀ / 2^n
N = 100 / (2^0.09375)
N = 94 g
Thus, 94 g of the nuclide is remaining in the patient's body,

A-Locations M and O are at the poles.
Explanation:
Locations M and O are located at the poles because they receive sunlight that is spread out over a large surface area. The poles receive sunlight at an angle to the surface and it causes the rays of the sun to spread out in all direction.
- At the equator, sunlight impinges directly on the surface and the solar radiation here is very much.
- It is important to know that the sun is overhead directly at the equator.
- The earth is tilted at an angle to sun and therefore, areas around the polar region will receive sunlight that is spread out in different directions over a large area.
- Away from the pole, the equator is directly facing the sun and it receives direct sunlight.

A closed container is any container sealed by means of a lid or other device that neither liquid nor vapor will escape from at ordinary temperatures.
“Ordinary” is the answer, hope this helps! :)
Neptune: its the 8th planet and since Pluto isn't a planet anymore Neptune is the farthest planet from the sun with a distance of around 2.8 billion miles (4.5 billion km) or (30.07 AU)
