1. Solar radiation arrives at the top of the atmosphere at a rate of 84k) per minute per square metre (84k]/min. m2). On average only 47% of this energy reaches ground level. Calculate
the amount of energy in kl reaching 2m2 at ground level over the period of 10800 seconds.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
