Why is the cosmic background radiation uneven in some places?

Answers

Answer 1

Answer:

Answer:

There is more space between our galaxy and distant galaxies, and the whole universe is expanding. ... Red shift shows that the galaxies are moving away from each other. Why is the cosmic background radiation uneven in some places? Matter was not spread out evenly in the early universe.

Answer 2

Answer:

Answer:

matter just wasn't spread out evenly in our universe after 400,000 years.

Explanation:the cmbr picture was as it was 400,000 years after the big bang it still looks the same as it does today though.when early galaxy's started to form they spread the radiation out unevenly with there gravity.

The approximate size of a galaxy can be measured by using the doppler effect. true or false.

Answers

Answer: The correct answer is False.

Explanation:

Scientists use the Doppler effect to understand the universe by determining the motion of the object.

Doppler effect: It is the phenomenon in which there is relative motion between the source and listener or source or observer.

Red shift and blue shift can be explained by using the concept of Doppler effect.

From red shift and blue shift, one can conclude that galaxies or stars are moving towards us or going away from us.

The light is shifted to longer wavelength which is red in the case of red shift. The light is shifted to shorter wavelength which is blue in the case of blue shift.

Therefore, "the approximate size of a galaxy can be measured by using the Doppler effect", the given statement is false.

Doppler effect just helps us in measuring the deviation of sound when observer or source of sound is in motion. Same thing can be observe in case of electromagnetic radiations but Irregular galaxies are different from elliptical and spiral galaxies because the contain very few stars. Just 'cause of that deviations, we can't use Doppler effect in measuring the size of galaxy

In short, Your Answer would be "False"

A 10.-kilogram object, starting from rest, slides down a frictionless incline with a constant acceleration of 2.0 m/sec2 for four seconds. What is the approximate weight of the object? A) 1 N B) 10 N C) 100 N D) 1,000 N

Answers

C) 100N

Given:

Mass of the object = 10kg

Acceleration due to gravity = 9.81m/s²

Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s² on Earth.

Formula for calculating the Weight of an object is expressed as;

Weight = mass × acceleration due to gravity

On substituting the values in the above formula:

Weight = 10×9.81

Weight = 98.1N

Hence, the approximate weight of the object is 100N.

Therefore, the correct option is option C.
