Answer:
Different star constellations are visible from Earth at different seasons of the year.
Explanation:
The reason the fact that we can see different constellations in the sky during different seasons on earth is the most compelling reason we travel around the sun is because if the sun travelled around the earth, certain constellations would only be visible in certain places. You’d have to travel to see certain ones.
However, you don’t have to do that because we travel around the sun, therefore travelling around other stars too.

E is the electric field intensity
B is the magnetic flux density
According to the statement " Collision <span>between two bodies in which the total kinetic energy of the two bodies after the collision is equal to their total kinetic energy before the collision."
The best answer is :
Option A " </span><span>BODY A COMES TO REST BODY B STARTS MOVING WITH INITIAL VELOCITY OF BODY A "</span>
Answer: A (
,309.8°)
B (2
, 315°)
C (
, 26.56°)
Explanation: To transform rectangular coordinates into polar coordinates use:
and 
For point A:
°
Point A is in the II quadrant, so we substract the angle for 360° since it is in degrees:
309.8°
Polar coordinates for point A is (, 309.8°)
For point B:
°
Point B is in IV quadrant, so:
315°
Polar coordinates for point B is (
, 315°)
For point C:
26.56°
Polar coordinates for point C is (, 26.56°)
