Two circuits have identical voltage sources. The only other elements in the circuits are resistors. The resistor in circuit A ha

s a resistance that is four times as large as the resistance of the resistor in circuit B (RA = 4RB ). Which statement below best describes the current flowing through the two circuits? (Ohm's law: V = IR) A. The current flowing through circuit A is as large as the current flowing through circuit B. B. The current flowing through circuit A is 2 times as large as the current flowing through circuit B. C. The current flowing through circuit A is 4 times as large as the current flowing through circuit B. D. The current flowing through circuit A is as large as the current flowing through circuit B.

The correct answer is not included among the choices you posted.
That may have happened because you mistakenly copied the wrong
text for choice A or D .... As the question appears, those two choices
are the same thing.

The correct answer is:
The current in circuit-A is 1/4 of the current in circuit-B.

A phone cord is 4.67 m long. The cord has a mass of 0.192 kg. A transverse wave pulse is produced by plucking one end of the tau
Olegator [25]

Answer:

91.017N

Explanation:

Parameters

L=4.67m, m=0.192kg, t = 0.794s, The pulse makes four trips down and back along the cord, we have 4 +4 =8 trips( to and fro)

so N= no of trips = 8, From  Wave speed(V) = N *L/t , we have :

V= 8*4.67/0.794 = 47.0529 m/s.

We compute the cords mass per length,  Let it be P

P = M/L = 0.192/4.67 = 0.04111 kg/m

From  T = P * V^2  where T = Tension, we have

T = 0.04111 * (47.0529)^2

T =  91.017N.

The tension in the cord is 91.017N

Thường ngày an đi bộ từ nhà đến trường mất 15 phút biết quãng đường từ nhà đến trường dài 1.5 km tính vận tốc đi thường ngày của
DedPeter [7]

Answer:

Speed in kilometer/hour = 6 kilometer / hour

Explanation:

Given;

Time taken to cover distance = 15 minute = 15 /60 = 0.25 hour

Distance of school = 1.5 kilometer

Find:

Speed in kilometer/hour

Computation:

Speed in kilometer/hour = Distance / Time

Speed in kilometer/hour = Distance of school / Time taken to cover distance

Speed in kilometer/hour = 1.5 / 0.25

Speed in kilometer/hour = 6 kilometer / hour

Imagine you are a geologist on a trip through the largest sphere on the planet. Identify the name of the sphere . As you travel
hoa [83]

Answer 1) : Hydrosphere.

Explanation : The largest sphere on the planet is hydrosphere, which is the combined mass of water found on a planet, available under, and above the surface of a planet, minor planet or natural satellite. It has been estimated that there are 1,386 million cubic kilometers of water on Earth. So, this is the largest sphere on a planet if you are traveling on Earth.

Answer 2) The other parts of the sphere are geosphere, atmosphere and biosphere.

Explanation : Geosphere - This sphere includes all the stuff that make up the crust and the core of the earth. It includes everything natural and lifeless that make up the surface of the earth. Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans.

Atmosphere - The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.

Biosphere - It is also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system, and largely self-regulating.
