"Black body radiation is the emission of electromagnetic radiation from a body that is in thermal equilibrium with its environment. It is emitted by all objects regardless of their temperature, but the intensity and spectral distribution of the radiation depends on the temperature of the body. As the temperature increases, the intensity of the radiation also increases and the peak wavelength shifts to shorter wavelengths.\n"
"Black body radiation is the emission of electromagnetic radiation from a body due to its temperature. It is a type of thermal radiation that is emitted from the surface of all objects that are at a temperature above absolute zero. It is a spectrum of radiation that is influenced by the temperature of the body and is independent of the composition of the emitting material.\n"

"The first prime number greater than 40 such that one plus the prime number is divisible by 3 is 43. To solve this, we first need to identify all of the prime numbers between 40 and 50. These are 41, 43, 47, and 49. We then need to check which of these, when added to 1, will be divisible by 3. The prime number that fits this criteria is 43. Therefore, the answer is 43.\n"
"The first prime number greater than 40 such that one plus the prime number is divisible by 3 is 43. To solve this problem, we can break down the question into two parts: finding the first prime number greater than 40, and then finding a number that is divisible by 3. \n",

"The first step is to find the first prime number greater than 40. A prime number is a number that is only divisible by 1 and itself. The next prime number after 40 is 41.\n",

"The second step is to find a number that is divisible by 3. To do this, we can add 1 to 41, which gives us 42. Now, we can check if 42 is divisible by 3. 42 divided by 3 is 14, so 42 is divisible by 3.\n",
