Final answer:
The correct level of radiant exposure that human skin can safely tolerate is (D) 1000.0 W/m², as this is approximately the intensity of full sunlight on a clear day, which human skin can endure for limited amounts of time.
Therefore, the Correct Option Is : B) 10.0 W/m²
Step-by-step explanation:
The question pertains to the level of radiant exposure that human skin can safely tolerate. Given the options provided (A) 1.0 W/m², (B) 10.0 W/m², (C) 100.0 W/m², and (D) 1000.0 W/m², we can refer to the nature of sunlight exposure on Earth's surface to infer an answer.
Sunlight intensity on Earth's surface can be as high as about 1.0 kW/m², or 1000 W/m², which is a level of radiant energy that human skin can tolerate, at least for short periods during activities like sunbathing. Hence, the correct answer is (D) 1000.0 W/m².
To add context, absorbing this amount of sunlight would result in a certain amount of pressure if the sunlight is fully absorbed, and this pressure is something the human skin can withstand under typical conditions.
People can tolerate radiant exposure of bare skin at levels up to 1.0 W/m². This is the maximum level at which the radiant energy from the sun can be absorbed by the skin without causing harm. If the radiant exposure exceeds this threshold, it can lead to sunburn and other negative effects on the skin.
