The graph below shows the blackbody radiation curves for four stars.Based on the graph, which of these conclusions is correct?

The star with very long wavelength does not emit light in the red part of the spectrum.
The star with very short wavelength does not emit light in the blue part of the spectrum.
The star with a wavelength of approximately 500 nm does not emit light in the green part of the spectrum.
The star with a wavelength of approximately 500 nm does not emit light in the red part of the spectrum.

Answers

Answer 1

Answer: The right answer for the question that is being asked and shown above is that: "The star with a wavelength of approximately 500 nm does not emit light in the red part of the spectrum." Based on the graph, wavelengths at approximately 500mn has less chance or can not emit light at the red part.

What is Rotation and Revolution of earth ?

Rotation refer to an object's spinning motion about its own axis

Revolution refers to the object's orbital motion around another object

The earth rotates on its axis 23 hours, 56 minutes and 4 seconds which is approximately equal to one day whereas the earth revolve around sun in 365 days , 6hours , 9minutes which is nearly equal to an year.

Hence , correct option is a) day . . . year

Answers

Answer:

$\Delta t = (\Delta x)/(v) \n\n$

Explanation:

Given the expression $v\:=(\Delta x)/(\Delta t)$ , we are to find the value of Δt from the expression. To find Δt, we will make Δt the subject of the formula from the given expression as shown;

$v\:=(\Delta x)/(\Delta t)\n\ncross\ multiply\n\nv*\Delta t = \Delta x\n\nDivide \ both\ sides \ of\ the \ resulting \ equation \ by \ v\n\n(v*\Delta t)/(v) = (\Delta x)/(v) \n\n\Delta t = (\Delta x)/(v) \n\n$

Hence the equivalent expression for $\Delta t = (\Delta x)/(v) \n\n$ .
