Following ideas provided an important step toward a more complete understanding of blackbody radiation is given below

Explanation:

Planck wanted to understand black body radiation. The black body may be modeled by a box, with a small hole.We heat the box up, wait for the system to reach a stationary state (at a fixed temperature), and see what kind of electromagnetic radiation (intensity as a function of frequency) comes out of the hole. In , Rayleigh and Jeans3 tried to apply classical mechanics to this problem, and they calculated correctly that the black body would emit the electromagnetic radiation with a distribution of frequencies. However, the larger the frequency, the larger its intensity - an absurd conclusion, what is known as an ultraviolet catastrophe.All materials emit light. A tungsten metal wire can illuminate a room with black body radiation at 2800 K. Black body radiation is a combination of spontaneous and stimulated emission from an array of thermally excited oscillators. Planck‘s radiation law describing this phenomenon is considered to be the foundation for modern physics and quantum theory. While no material behaves exactly as a black body, all emit light by this mechanism. External energy in the form of heat enters the materials system, and light is emitted to maintain a steady-state, constant temperature.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
