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

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?

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.

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 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

When a 6 Ω resistor is connected across the terminals of a 3 V battery, the number of coulombs passing through the resistor per second is

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

Radio waves pass through us easily every day with no bad effects. Gamma Rays will kill you in large doses. the difference between these two forms of waves are in their energy.

What is wave ?

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.

There are two types of the wave longitudinal wave and transverse wave.

The energy of the electromagnetic photon is given by frequency times plank's constant. Hence energy is directly proportional to the requency. The frequency of the radio waves is far smaller than the gamma rays hence it has low energy. this is the difference, which leads gammas rays  injurious to heath.

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.
