When a star or galaxy is moving away from us, we observe the Doppler effect by seeing the lines in its spectrum Group of answer choices blue-shifted (shifted toward the blue or violet end of the light spectrum) you can’t fool me, the Doppler effect only applies to motions on Earth, not to the motions of the stars and galaxies become darker and darker (like a blackbody) yellow-shifted (shifted so all the colors become a little bit yellower) red-shifted (shifted toward the red end of the light spectrum)

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
