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.

a. You have a 10 volt parallel circuit, with 2 resistors on it. What is the voltage across the first resistor? Across the second?
b. You have the same two resistors on a 10 volt series circuit. Will the voltage going into the second resistor be more, less, or the same as that going into the first resistor? Exact numbers aren’t needed!
c. You have a series circuit with a current of 6 amps and three resistors on it, with resistances of 10 ohms, 5 ohms, and 6 ohms, respectively. What is the voltage of this circuit? Show your calculation.
Answers
b. The same. In a series circuit, the voltage is split between the resistors. Since the resistors have the same resistance, the voltage across both of them will be the same.
c. V = IR (Ohm’s law)
I = 6 amps
R = 10 + 5 + 6 = 21 ohms (because in a series circuit, the total resistance is just the sum of all of the resistors’ resistances)
V = (6)(21) = 126 volts

How is a lunar eclipse similar to a solar eclipse? How are they different?
Answers
Answer:
they moon and sun are a factor in both of them
Explanation:
Answer:
From our perspective on Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon. When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. Also they are similar by An eclipse occurs when one celestial object obscures another celestial object. In the case of a solar eclipse, the moon moves between the Earth and the sun, thus obscuring the sun. A lunar eclipse occurs when the Earth moves directly between the sun and the moon. Either type of eclipse can be total or partial.

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.

Explanation:
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. ... Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules.

How is a compound formed differently than a mixture, and how can each be broken down into their original substances?
Answers
A mixture is a impure substance
Compounds can be broken into simpler substances only by chemical methods
Mixtures can be separated by physical and chemical methods
The compound is chemically formed while the mixture is physically mixed. The compound can be broken down into its original substances via chemical reactions while the mixture can be separated through physical forces.
What are the mixture and compound?A pure substance can be described as composed of two or more elements that are chemically combined and exhibit a set composition such type of a pure substance is called a compound. For example, water is a pure compound made of oxygen atoms and hydrogen atoms in a ratio of 2:1.
A mixture can be described as composed of two or more different substances which are physically combined and have no chemical change. A mixture can be broken down into its original components.
We have two types of mixtures one is homogeneous and the other is heterogeneous. The composition of a heterogeneous mixture is non-uniform in the entire mixture whereas the composition in a homogeneous mixture remains constant in the entire mixture.

Imagine you are part of a group of engineers who need to test a scale model of a footbridge. It will be a $\frac{1}{20}$120 scale model of the bridge. The footbridge will cross over a busy road and allow people to cross the road safely. How could a relatively small design error of 2 centimeters in the model system cause a significant problem in construction of the bridge?
Pls help me u will get branilest pls help me
Answers
Answer:
The problem will be because:
The error in the construction of the bridge will be actually 40 cm.
Explanation:When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error.

What force causes the measurement of weight?
Answers
Answer:
Gravity
Explanation:
Gravity is what causes you to weigh more or less.
What is gravity? Gravity is the force that pulls things together. Larger things with larger masses have more gravity. When you are on Earth, you would weigh more than on the moon, about 6 times more, in fact, because the gravity on Earth is 6 times stronger.
