R2

Answers

Complete question is;

A 50.-ohm resistor, an unknown resistor R, a 120-volt source, and an ammeter are connected in a complete circuit. The ammeter reads 0.50 ampere.

A) Calculate the equivalent resistance of the circuit shown.

B) Determine the resistance of resistor R shown in the diagram.

Answer:

A) R_eq = 240 Ω

B) R = 190 Ω

Explanation:

A) To get the equivalent resistance, we will use the formula;

R = V/I

Where;

V is Voltage

I is current

R is equivalent resistance

From the question, V = 120 V and I = 0.5A

Thus;

R_eq = 120/0.5

R_eq = 240 Ω

B) From the image, we see that the resistors are connected in series.

Formula for resistors in series is;

R = R1 + R2 +..... Rn

Thus;

240 = 50 + R

R = 240 - 50

R = 190 Ω

A) The equivalent resistance of the circuit shown will be  240 Ω.

B) The resistance of resistor R will be 190 Ω

What is resistance?

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The given data in the problem is;

R is the resistance = 50.-ohm

v is the voltage = 120-volt source

I is the value of the current =0.50 ampere.

A) The equivalent resistance of the circuit shown will be  240 Ω.

According to ohm's law

[tex]\rm R= \frac{V}{I} \\\\ \rm R= \frac{120}{0.5} \\\\ \rm R=240 \ ohm[/tex]

Hence the equivalent resistance of the circuit shown will be 240 Ω.

B) The resistance of resistor R will be 190 Ω

The given resistors are connected in the series;

R = R1 + R2 +..... Rn

240 = 50 + R

R = 240 - 50

R = 190 Ω

Hence the resistance of resistor R will be 190 Ω

How the choice of building materials and techniques can help them cool down faster, after heating up.

Answers

Answer:

The choice of building materials and techniques can help them cool down faster, after heating up is explained below in brief details.

Explanation:

Building materials

Buildings that are composed of rock, bricks, or pavement, or inserted into the territory, can seem cooler thanks to the great "thermal mass" of these elements – that is, their capability to assimilate and discharge heat gently, thereby softening temperatures over time, producing daytime cooler and night-time warmer.

In order for a roller coaster to work, why does the hill the cart climbs need to be higher than the top of the loop?

Answers

Answer:

The concept of potential energy, often referred to as energy of position, is very simple: As the coaster gets higher in the air, gravity can pull it down a greater distance. ... The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill.

Potential energy, also known as energy of position, is a pretty straightforward idea. As the roller coaster rises in the air, gravity has a greater ability to pull it down.

What does the hill the cart climbs need?

An easy illustration involves a stopped car at the summit of a hill. The car drives faster as it goes down the hill, which results in an increase in kinetic energy and a decrease in potential energy. The vehicle changes kinetic energy into potential energy as it ascends the hill.

They are higher up at the top of the hill, thus they have more potential energy. Moving down a slope transforms potential energy into kinetic energy, while moving up a hill transforms kinetic energy into potential energy.

Therefore, You can release the potential energy you accumulate while climbing a hill as kinetic energy, which is the energy of motion that propels you down the hill.

When drawing a vector, you should represent the magnitude of the vector by the length of the arrow. A. True O B. False​

Answers

Answer: A. True

Explanation:

Answer:

A. True

Explanation:

A vector in this sense is a thing that has both magnitude (length) and direction.

Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.

This doesn't give any information about where you started or any information about where you ended up after those 2 hours.

This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.

Velocity is a vector.

Answers

Answer:

yes it does exert a force, it pushes it up

Explanation:

this is called normal force

if it didn't exert a force the book would keep going down

according to newton every force has an equal amd opposite reaction

so the book exerts a force on the table and vice versa

A weight-lifter raises a 2000 N weight through a vertical height of 2.0m in 0.80 s.
What useful power does he develop in doing this?
A
800 W
B
3200W
с
4000 W
D
5000W

Answers

Answer:

D. 5000W

Explanation:

Given the following data;

Force = 2000N

Distance = 2m

Time = 0.8s

To find the power;

First of all, we would determine the workdone by the weightlifter

Workdone = force * distance

Workdone = 2000 * 2

Workdone = 4000N

Now, we can find the power using the formula;

Power = workdone/time

Substituting into the equation, we have

Power = 4000/0.8

Power = 5000 Watts
