Household solar panels typically have an efficiency of 15.0%. if the intensity of sunlight is assumed to be a constant 9.80 ✕ 102 w/m^2, what should be the total area of rooftop solar panels on a house in order to supply an average of 19.2 kw each day? efficiency denotes the percentage of incident solar energy that is converted to electricity by the solar panel. (assume the power is only needed during the day, when the sun is up, and that sunlight is always incident on the solar panels when the sun is up.) answer in meters squared

The total area of rooftop solar panels is 130.61 m².

Explanation:

Given that,

Efficiency = 15%

Intensity of sunlight

Power = 19.2 kW/d

Let sun's power need be P.

We need to calculate the power

We need to calculate the total area of rooftop solar panels

Using formula of power

Where, I = intensity

A = area

P = power

Put the value into the formula

Hence, The total area of rooftop solar panels is 130.61 m².

it about 600 mph from what i calculated

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
