ANSWER ALL OF THEM NOT PICKING

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

Answer 1

a. In a parallel circuit, the voltage across every resistor is the same. So, the voltages across the first resistor and second are both 10 volts.

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

Explanation:

A) higher frequency and C) a shorter wavelength.

As far as I know, you calculate frequency on a graph using the number of peaks you can see. Since the wavelength is shorter (the distance between two peaks on the wave), the frequency should also be higher as more fit on the graph.

Which object has the most kinetic energy?

A. a train that is stopped
B. a car moving at a slow speed
C. a train moving at a slow speed
D. a car that is stopped at the top of a hill

Answers

C

Explanation: kinetic energy means that the object is moving, automatically eliminating A and D since they are both stopped. The formula for kinetic energy is KE=1/2m(v^2) (m= mass and v= velocity). Since the train has more mass than the car, the train has more kinetic energy.

C is the right answer because train has more mass than car

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

Why is it important to know how the sun's energy affects the lower atmosphere if you are planning to harness the power of moving air?

Answers

it determines pressure and determines the movement of the wind.

It is important to know the affects of temperature on pressure and thereby on winds. At high temperature, the pressure will be high and thus, the winds will pass from that area.

What is winds?

Wind is the passage of air through the atmosphere. The uneven distribution of temperature leads to the difference in pressure. The pressure gradient results in wind.

Air pass from high pressure area to low pressure area. According to Gay- Lussacs law, at the pressure gases is directly proportional to the temperature.

Hence, as the temperature increases, pressure in that area increases, leads to air currents to the opposite direction. This will definitely affects harnessing.

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
