The north celestial pole (and also the south) are described as two imaginary points that project on the axis of rotation of the earth, indefinitely towards space and that intersects with the celestial sphere (Remember that the earth has a slight inclination with respect to to its axis of rotation). The north and south celestial poles are directly above the head of someone located at the north or south pole of the earth.
Correct Answer is A.
I believe destructive interference.
EXPLANATION: when two waves meet and a crest of one wave is parallel to the crest of another destructive interference occurs. You subtract the amplitude of the two waves that meet and you’ll get the amplitude of the wave they’ll form. If it is the same amplitude the result will be zero.
Hope this helps
Answer:
Thermal physics is the combined study of thermodynamics, statistical mechanics, and kinetic theory of gases. This umbrella-subject is typically designed for physics students and functions to provide a general introduction to each of three core heat-related subjects. Other authors, however, define thermal physics loosely as a summation of only thermodynamics and statistical mechanics.
Explanation:
If I ask you to tell me the acceleration of gravity on Earth, you'll tell me a number. That acceleration of gravity is always that number, no matter WHEN you measure it. t doesn't change. So the graph of it is the number. The graph of a number is a horizontal line. Its equation is:
. Y = (the number) .
The correct choice is ' A ' .
