A 1 cm2 silicon solar cell has a saturation current of 10A and is illuminated with sunlight yielding a short-circuit photocurrent of 25 mA. Calculate the solar cell efficiency and fill factor.

Answers

Answer 1

Answer:

The answer is "13% and 83%"

Explanation:

The highest power is generated for:

[tex]\to \frac{dP}{dV_a}=0= I_s(e^{\frac{V_m}{V_t}} -1)-I_{Ph} +\frac{V_m}{V_t} I_s e^{\frac{V_m}{V_t}}[/tex]

 Where voltage, [tex]V_m[/tex], was its calculated maximum power wattage.  This same following transcend national stable coins the power output:

[tex]\to V_m=V_t \ In \frac{1+\frac{I_{ph}}{I_s}}{1+\frac{V_{m}}{V_t}}[/tex]

The accompanying consecutive values of [tex]V_m[/tex] are done utilizing iteration and an initial value of 0.5 V:

[tex]\to V_m = 0.5,\ 0.542,\ 0.540 \ V[/tex]

Efficacy is equivalent to:

[tex]\eta = |\frac{V_{m} I_{m}}{p_{in}}| =\frac{0.54 \times 0.024}{0.1}=1.3\%[/tex]

Currently, [tex]I_m[/tex] was calculated with the formula of voltage [tex]V_m[/tex] (4.6.1) as well as the sun is presumed to produce  [tex]100 \frac{mW}{cm^2}[/tex] of power.

The fulfillment factor is equal to:

fill factor[tex]= \frac{V_{m} I_{m}}{V_{oc}I_{sc}}= \frac{0.54 \times 0.024}{0.62 \times 0.025}=83\%[/tex]

where open circuit tension of equations (4.6.1) and I = 0. is calculated. The current is equal to the total current of the photo.

Which of these is an example of work being done on an object a. Holding a heavy piece of wood at a construction site. b. Trying to push a car that doesn't move out of deep snow. c. Pushing a child on a swing. d. Holding a door shut on a windy day so it doesn't blow open.

Answers

Answer:

I would say the best choice, would be Choice C.

For all of these scenarios a force is being applied to displace an object. But the displacement occur in the case of trying to push a car and pushing a child on a swing. Thus, options b and c are correct.

What is work done?

Work done in physics is the dot product of force and displacement. Therefore, every work done is associated with a force but not all force result in work done. Those force, which result in a displacement will do work done.

Holding a heavy piece of wood does not make a displacement in the object. Similarly, when we hold the door to stop we just apply a force and not displacing the door. In both cases work done is zero.

When we push a car to make it move and any movement from the side of the car result in a work done. Similarly in when we push a child in a swing we make the swing move a distance by applying force. Thus work is being done on the object.

If a total of 1250 offspring were obtained from your cross, determine the number of offspring that you would expect to obtain that represent a single crossover event between pr and vg if interference does not occur.

Answers

Answer:

106 single crossover events

Explanation:

Total number of offspring = 1250

Determine the number of offspring that would be expected

( Rf between the genes vg and Pr ) * ( Total number of progeny )

  =   0.125 * 1250 ≈ 156 ( value for single and double crossovers )

next :

( value of the Rf of double crossovers ) * ( Total number of progeny )

= (0.322 * 0.125) = 0.04025  * 1250 = 50

Hence the number of offspring expected to obtain/represent a single crossover event between pr and vg

=  156 - 50 =  106

An 8 kg toddler is running at a speed of 10 m/s.
how much energy does he have?

Answers

To find the Kinetic energy this is the equation


KE=1/2mv^2

so we know the mass (m) which is 8kg

we also know the velocity (v) which is 10 m/s

so we plug that into the equation and it should look like this - 1/2(8kg)(10m/s)^2 now we solve

so 1/2 x 8 = 4 so then we just do (4)(10)^2 which gets us 400.

Since kinetic=Joules

The answer is 400 J

Why do eclipses not happen every lunar cycle? (If someone could explain this in a paragraph? it doesn’t have to be very descriptive or detailed)

Answers

Answer:

Exploratorium Senior Scientist Paul Doherty explains why not—the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse.

Explanation:

Hope it helps

Answer:

It's true that the moon goes around Earth every month, but it doesn't always get in Earth's shadow. The moon's path around Earth is tilted compared to Earth's orbit around the sun. The moon can be behind Earth but still get hit by light from the sun. ... This is why we don't get a lunar eclipse every month.

A horizontal force of 164 N is applied to move a 55 kg television set across a 9 m level surface. What is the work done by the force on the television set?

Answers

Answer:

Workdone = 1476 Nm

Explanation:

Given the following data;

Force = 164 N

Mass = 55kg

Distance = 9 m

To find the work done;

Workdone = force * distance

Workdone = 164 * 9

Workdone = 1476 Nm

Therefore, the work done by the force on the television set is 1476 Nm.

C. Gravitational forces are weakest when one object is more massive than the other.

Answers

Answer:

Explanation: the table shows during an experiment

Gravitational forces are strongest between objects with identical masses,  claims are supported by the data. Option B is correct.

What is Newton's law of gravitation?

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

When mass increases and distance reduces, gravity rises. Gravity also lowers when the distance between two points grows and the mass decreases.

From the table, it is observed that gravitational forces are strongest between objects with identical masses,  claims are supported by the data.

Hence, option B is correct.
