Hey Lenny lately I’ve been having a rough time in the water cycle. It all started when I was chilling in my favorite location the “glaciars” and suddenly the sun turned me into liquid form. Next thing I know I am hurdling down a river straight into a massive lake. Personally this is my least favorite stage of the water cycle because of kids and bacteria that lurk in the water, very scary things. I didn’t stop at the lake very long, and instead sunk into the soil in a process called collection so I could become ground water. Underground reservoir’s are much more peaceful then lakes and I wanted to stay there. However I was forced up a water well pump shortly after and sent through a long tube. Me and couple of the friends I met on the way were all dispersed over a giant grass feild. Many molecules in the group were captured by the hostile plants but I escaped through the means of evaporation. Currently I have condensed into cloud form and I am roaming the skies looking for you, when you get this let me know and I’ll percipitate in your area! P.s I found this photo of us freezing over in the ice age lollll.

Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL

Which seismic waves are call “push/pull” because they compress and extend as theymove through the earth? *

Which type of seismic wave can move through solid layers of the earth but not through the liquid outer core? *

Which seismic wave is the first to reach a seismic station, and therefore is the fastest? *

Answers

Answer:

1.A                                                                                                                  2.P waves are the fastest kind of seismic wave. a longitudinal P wave has the ability to move through solid rock and fluid rock, like water or the semi-liquid layers of the earth. It pushes and pulls the rock it moves through in the same way sound waves push and pull the air.                                                                     3.The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium. It is this property of S waves that led seismologists to conclude that the Earth’s outer core is a liquid.                                                                        4.P Waves The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.

Answers

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

No it would not conduct electricity as it is a insulator

Your friend is celebrating her 25 th birthday today and wants to start saving for her anticipated retirement at age 65 . She wants to be able to withdraw $250,000 from her saving account on each birthday for 20 years following her retirement; the first withdrawal will be on her 66th birthday. Your friend intends to invest her money in a retirement account, which earns 8 percent return per year. She wants to make an equal annual deposit on each birthday into the account for her retirement fund. Assume that the annual return on the retirement account is 8 percent before retirement and 5 percent after retirement. If she starts making these deposits on her 26 th birthday and continue to make deposits until she is 65 (the last deposit will be on her 65 th birthday and the total number of annual deposits is 40), what amount must she deposit annually to be able to make the desired withdrawals at retirement? (Hint: One way to solve for this problem is to first find the value on your friend's 65 th birthday of the $250,000 withdrawal per year for 20 years after her retirement using the annual return after retirement and then find the equal annual deposit that she needs to make from her 26th birthday to 65 th birthday using the annual return before retirement.)
