Answer:
Wavelength, 
Frequency, 
Explanation:
We need to find the intensity of the radiation is a maximum for a black body at 298 K. It can be calculated using Wein's displacement law. It is given by :


Here, T = 298 K


If f is the frequency of black body radiation. It is given by :



Hence, this is the required solution.
Kepler's third law is founded on a mathematical formula that is based on
the inverse relationship between a planet's orbital velocity and its distance
from the sun.
You weigh slightly more at the beach than on top of a mountain, because at the beach, you're closer to the center of the Earth.
