Answer 1

Answer:

The correct answer is D: The time it takes the cheetah to travel 110 kilometers.

Explanation:

To find distance, you need to use the formula d = st, or distance equals speed times time. Therefore in order to get the accurate distance, use this formula to help.

Hope this helped, have a good day!

Answer 2
The time it takes the cheetah to travel in one hundred kilometers. Last one

For the first one it is Electromagnetic waves and the second one is longitudinal and transverse  and water water waves (I’m sorry if I get the second one wrong for you but the first I put is right)

Explanation:

An electromagnetic wave can travel through empty space or through matter.There are 2 types of wave motion-transverse ,longitudinal and a combination of both.

What is an electromagnetic wave?

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

What happens to the atoms that make up hydrogen fuel as it burns?

Answers

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Explanation:

When hydrogen fuel burns, its atoms combine with oxygen atoms to form water molecules. So the atoms that make up hydrogen fuel become part of the water molecules.

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

Answer: the correct one would be option B.

Explanation:

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

lan wonders if sunscreen lotion will dry out if it is exposed to light. The table below shows what happens when different types of light hit the sunscreen
Based on this information, which type of light is more likely to dry out the sunscreen?

a
The ultraviolet light is more likely to dry out the sunscreen because the ultraviolet light bounces off of the sunscreen, which means that it has more energy.

b
The X-ray light is more likely to dry out the sunscreen because the X-ray light can pull energy out of the sunscreen when it passes through the sunscreen.


c
There is no way to know because they are two different types of light, and different types of light can change material in different ways.


d
Neither type of light is likely to dry out the sunscreen because the sunscreen does not take in energy from either the ultraviolet light or the X-ray light.

Answers

D. I hope this helps with what your doing

Sunscreen does not absorb any kind of light especially ultraviolet light and x-rays. They protect skin from these lights. Hence option D is correct.

What is sunscreen?

Sunscreen lotion is a chemical which is used to protect skin from hazardous lights. Sunlight consists of ultraviolet light and X-rays which causes damages to skin. They even damage the DNA of humans.

Sunscreen is made of some nanoparticle formulation. They are capable of screening the skin from the hazardous light. The nanoparticles in the lotion will enter the cell without causing any toxicity and will form a protective coating around the nucleus.

Therefore, either type of light is likely to dry out the sunscreen because the sunscreen does not take in energy from either the ultraviolet light or the X-ray light. Hence, option D is correct.
