What risks does nuclear waste pose to Earth or the sun or outer space?
Answer:
It could pollute other planets. Nuclear waste might be attracted by the gravitational pull of the sun and disintegrate there instead. The waste storage spacecraft could crash into a planet, moon, or another astronomical body. It could be dangerous for other life forms out there.
Explanation:
A container of 56mL is at STP, The pressure is increased to 3.6atm and the volume to 162 mL.
What is the new temperature?
Answer:
T2 = 2843.1 oK. This is a huge temperature. Check it for errors.
Explanation:
Remark
This is the same question as the other one I've answered. Only the numbers have been altered.
Givens
v1 = 56 mL
P1 = 1 atm
T1 = 273o K
v2 = 162
P2 = 3.6 atm
T2 = ?
Formula
Vi * P1 / T1 = V2 * P2/T2
Solution
Rearrange the formula so T2 is on the left
T2 = V2 P2 * T1 / (V1 * P1) Now just put the numbers in.
T2 = 162 * 3.6* 273 / (56 *1)
T2 = 159213.6/56
T2 = 2843.1
If a solution is saturated and more salt that is added falls to the bottom of the container what is it called?
A: Supersaturated
B: Saturated
C: Unsaturated
Answer:
The answer is B
Explanation:
A solution that contains a relatively low concentration of solute is called dilute, and one with a relatively high concentration is called concentrated. If we add more salt to a saturated solution of salt, we see it fall to the bottom and no more seems to dissolve.

Which is the daughter isotope? Superscript 218 subscript 86 R n. Superscript 4 subscript 2 upper H e. Superscript 222 subscript 88 upper R a.
The daughter isotope which is present in the given radioactive decay is ²¹⁸₈₆R.
What is daughter isotope?A daughter isotope is the isotope that remains following the radioactive decay of an original isotope.
In the question parent nuclei is given that ²²²₈₈R, and given chemical equation is:
²²²₈₈R → ²¹⁸₈₆R + ⁴₂He
In the above equation ²¹⁸₈₆R is the daughter nuclei and ⁴₂He is the emitted particle or rays.
Hence ²¹⁸₈₆R is the daughter isotope.

The table below shows the time that the Moon rose and set over a few days.
Date Moon Rose Moon Set
March 2 4:59 a.m. 2:16 p.m.
March 3 5:38 a.m. 3:14 p.m.
March 4 6:11 a.m. 4:14 p.m.
Which of the following is the best prediction for the times that the Moon will rise and set on March 5?
A.
rise at 5:34 a.m., set at 3:18 p.m.
B.
rise at 7:42 a.m., set at 6:54 p.m.
C.
rise at 6:20 a.m., set at 4:16 p.m.
D.
rise at 6:40 a.m., set at 5:14 p.m.
This is dealing with science
C, best estimates for the times the Moon will rise and set on March 5: rise at 6:20 a.m., set at 4:16 p.m.
When does the moon rise?Observing the pattern from the previous days provides the best estimate for the times the Moon will rise and set on March 5. From March 2 to March 4, the Moon rose later and set later every day. Based on this trend, it is possible to forecast that the Moon will rise and set later on March 5 than it did on March 4.
Rises at 6:20 a.m., set at 4:16 p.m. - This option follows the pattern observed in the previous days, with the Moon rising later and setting later.
Therefore, the best possibility for the times the Moon will rise and set on March 5 is 6:20 a.m. and 4:16 p.m.

Answer:
rise at 6:40 a.m., set at 5:14 p.m.
Explanation:
"The table shows that the Moon rose about 33 to 39 minutes later each day. The moon rose at 6:11 a.m. on March 4. So, the best prediction for March 5 is that the moon will rise at 6:40 a.m. The table shows that the moon set about 1 hour later each day. The moon set at 4:14 p.m on March 4. So, the best prediction for the next day is the moon will set at 5:14 p.m."

.What is the KE of a baseball that has a mass of 100 kg and is traveling at 5 m/s?
Answer:
1250joules
Explanation:
The kinetic energy is energy in motion and it's formula is
KE =1/2MV^2
M represent mass which is 100Kg.
V represent velocity which is 5m/s
Therefore, KE = 1/2×100×5× 5
= 50 × 25
KE= 1250joules

Roots absorb the water they need for photosynthesis through tiny outgrowths called ______________
Answer:
The correct answer is - root hairs.
Explanation:
Root hairs or absorbent hair are the very small tubular outgrowth present in the epidermis of the roots of the plant that helps plants in absorbing the water from the soil pores into the plants. Water is an essential reactant in the photosynthesis process.
By their elongation increases the surface of exchange between plants and soil for better absorption. The major function of the root hairs to absorb the water and the nutrients from the soil to the plant.

What is used up in and stops a chemical reaction?
Answer:What is used up in and stops a chemical reaction? (a) percent yield (b) limiting reactant (c) theoretical yield (d) excess reactant
The correct option is (b)
Explanation:
A chemical reaction is a chemical combination,rearrangement or disintegration of chemical substance(s) (called reactants) to form new chemical substance(s) (called products).
A limiting reactant is the reactant that is totally used up during the course of a reaction. When this reactant is used up, it limits the amount of products formed and eventually stops the chemical reaction.
Explanation:
The limiting reagent is the reactant that is used up completely. This stops the reaction and no further products are made. ... This method is most useful when there are only two reactants. The limiting reagent can also be derived by comparing the amount of products that can be formed from each reactant.
