An individual white LED (light-emitting diode) has an efficiency of 20% and uses 1.0 W of electric power. a. How many LEDs must
Neporo4naja [7]

Answer:

8, 8 W

Explanation:

The useful power of 1 Light Emitting Diode is

0.2\times 1=0.2\ W

Total power required is 1.6 W

Number of Light Emitting Diodes would be

n=\dfrac{1.6}{0.2}\\\Rightarrow n=8

The number of Light Emitting Diodes is 8.

Power would be

P=8\times 1=8\ W

The power that is required to run the Light Emitting Diodes is 8 W

Help! I can't remember how to calculate this.
Mars2501 [29]
You need to draw two lines from the head of the arrow: one parallel to the axis (which will be bent) and the other one passing through the center of the converging lens <span>(which will continue straight) </span>and see where they intersect.

If the arrow is at an infinite distance, the image will be point-like in F.
If the arrow is at a distance greater than 2F, the image will be upside down between F and 2F.
If the arrow is at a distance of 2F, the image will be upside down in 2F.
If the arrow is at a distance between F and 2F, the image will be upside down beyond 2F.
If the arrow is at a distance F, all rays proceed parallel to each other and no image is formed.
If the arrow is at a distance smaller than F, the image will be virtual.

Therefore, the correct matches are 1B, 2C, 3D, and 4A.

How much heat transfer is required to raise the temperature of a 0.750-kg aluminum pot containing 2.50 kg of water from 30.0ºC t
lorasvet [3.4K]

Answer:

Part a)

Q = 2.47 \times 10^6

Part b)

t = 4950.3 s

Explanation:

As we know that heat required to raise the temperature of container and water in it is given as

Q = m_1s_2\Delta T_1 + m_2s_2\Delta T_2

here we know that

m_1 = 0.750

s_1 = 900

m_2 = 2.50 kg

s_2 = 4186

\Delta T_1 = \Delta T_2 = 100 - 30 = 70^oC

now we have

Q_1 = 0.750(900)(70) + (2.5)(4186)(70) = 779800 J

now heat require to boil the water

Q = mL

here

m = 0.750 kg

L = 2.25 \times 10^6 J/kg

now we have

Q_2 = 0.750(2.25 \times 10^6) = 1.7 \times 10^6 J

Now total heat required is given as

Q = Q_1 + Q_2

Q = 779800 + 1.7 \times 10^6 = 2.47 \times 10^6 J

Part b)

Time taken to heat the water is given as

t = \frac{Q}{P}

here we know that

power = 500 W

now we have

t = \frac{2.47 \times 10^6}{500} = 4950.3 s
