An electric iron consumes energy at a rate of 840 W when heating is at the maximum rate and 360 W when the heating is at the minimum. The voltage is 220 V. What are the current and the resistance in each case?

Don't spam ​

Answers

Answer:

See Explanation

Explanation:

We know that;

P= IV

Where;

P = power

I= current

V = voltage

Here, we have a voltage of 220V

Hence, for maximum rate;

P= IV

I = P/V

P = 840 W

V= 220 V

I= 840 W/220 V

I= 3.8 A

V = IR

R = V/I

R = 220/3.8

R = 57.9 Ω

For minimum heating;

P= 360 W

V= 220 V

I = P/V

I = 360 W/220V

I= 1.6 A

V= IR

R = V/I

R = 220 V/1.6 A

R = 137.5 Ω

What's the difference between the period and the
circumference?

Answers

Answer:

The circumference of a circle is the distance around it (linear) while a period is the completion of a cycle or the length from one peak to the next of a periodic function

Explanation:

Circumference is the distance around a circle while period is the time taken for one revolution around the circle.

What is a Circle?

This is a round plane figure whose points are equidistant from a fixed point. The circumference is total distance round the circle.

On the other hand, period refers to the time taken for one revolution around the circle.

Explanation:

In parallel circuits the current splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the current isn't the same everywhere in a parallel circuit.

A plumber is going to put two pipes in a wall, one in front and one in back. The pipes will be touching once they are installed. Both pipes are the same size and have the same number of molecules. The diagram above shows the pipes now, before they have touched. Use the information in the diagram to answer the question.

How does the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch? What will happen after the pipes have been touching for a while?

Answers

Answer:

They become the same exact tempature

Explanation:

Since they got connected it should be the same.

the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch by using same temperature.

what is temperature ?

Temperature is the measure of hotness or coldness expressed in terms of any of several arbitrary scales and it indicate the direction in which heat energy will spontaneously flow from a hotter body to a colder body.

It is not the equivalent of the energy of a thermodynamic system like burning match is at a much higher temperature than an iceberg whereas the total heat energy contained in an iceberg.

Temperature which is similar to pressure or density known as intensive property  that is independent of the quantity of matter is considered as distinguished from extensive properties, such as mass or volume.

Answers

Answer:

Given that - R = 6 ohm

V = 3 volt

n = ?

so by ohms law , V = I X R

I = V \ R = 3 \ 6 = 0.5 A

we know that I = Q / T here t is 1 sec

Q = I X T = 0.5 X 1 = 0.5 C

By the law of quantization ,

Q = n x e

n = Q / e = 0.5 / 1.6 x 10 ^-19

A 25 N force stretches a spring 0.280 m. What was the spring constant?

Answers

Answer:

the  spring constant is -89.2857 n/m

Explanation:

The computation of the spring constant is shown below:

As we know that

Force in newtons = Spring constant × amount of extension

F = -k × x

where

F = 25 N

And, x = 0.280m

So, the spring constant would 2  

= 25N ÷ 0.280 m

= -89.2857 n/m

Hence the  spring constant is -89.2857 n/m

An ideal gas expands isothermally performing 4.30 x 10³ of work in the process. Calculate (a)
the change in internal energy of the gas, and (b) the heat absorbed during this expansion.​

Answers

Answer:

The solution of the given query is explained below in the explanation portion.

Explanation:

Given value is:

Work,

⇒  [tex]W=4.30\times 10^3 \ J[/tex]

(a)

The change in the internal energy will be:

⇒  [tex]\Delta V=\frac{3}{2}nR(\Delta T)[/tex]

Throughout the isothermal procedure, The temperature will be constant "ΔT = 0".

then,

⇒  [tex]\Delta V = \frac{3}{2}nR(0)[/tex]

⇒  [tex]\Delta V = 0 \ J[/tex]

(b)

As we know,

⇒  [tex]\Delta V = Q-W[/tex]

On substituting the value, we get

⇒      [tex]0=Q-W[/tex]

On adding W both sides, we get

⇒    [tex]W=Q-W+W[/tex]

⇒    [tex]W=Q[/tex]

On substituting the given value of "W", we get

⇒     [tex]Q=4.30\times 10^3 \ J[/tex]

A 100 N force is applied to move an object a horizontal distance of 5 meters at constant speed in 10 seconds. How much power is done?

Answers

F= 100 N , d= 5 m
Time taken = 10 sec
Power= work/time
[ work = f*d]
100*5/10
= 500/10
= 50 watt

The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W

We'll begin by calculating the energy. This can be obtained as follow:

Force (F) = 100 N

Distance (s) = 5 m

Energy (E) =?

E = F × s

E = 100 × 5

E = 500 J

Finally, we shall determine the power. This can be obtained as follow:

Energy (E) = 500 J

Time (t) = 10 s

Power (P) =?

[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]

P = 50 W

Therefore, the power used in moving the object is 50 W.

A force of 120 N is applied to the front of a sledge at an angle of 28.00 above the horizontal so as to pull the sledge a distance of 165 meters. How much work was done by the applied force?

Answers

Answer:

Workdone = 17482.36 Joules

Explanation:

Given the following data;

Force, F = 120 N

Angle, d = 28.0°

Distance, x = 165 m

To find the work done, we would use the following formula;

Workdone = FxCosd

Substituting into the formula, we have;

Workdone = 120*165*Cos(28)

Workdone = 19800 * 0.8830

Workdone = 17482.36 Joules
