Cosmic Microwave Background

Explanation:

The cosmic background radiation gives us a glimpse into the formative years of our universe. The cosmic background radiation contains radiation from the epoch of recombination of the Big Bang. The radiation is most visible in the microwave region of the electromagnetic spectrum. The radiation poses a strong case that the universe originated from the big bang.
That's called the "Cosmic Microwave Background".  (CMB)
It was discovered in 1965, and its discoverers were awarded

A water wave travels across a 42-meter wide pond in 7.0 seconds. The speed of the wave is _____. 292 m/s 49 m/s 6.0 m/s 0.17 m/s

Answers

           Speed  =  (distance covered) / (time to cover the distance).

The speed of anything that covers 42 meters in 7 seconds is

               (42 meters)  /  (7.0 seconds)

           =    (42 / 7.0)      (meters/second)

           =             6.0 m/s . 

Answer:

6.0 m/s

Explanation:

A water wave travels across a 42-meter wide pond in 7.0 seconds. The speed of the wave is _____.

292 m/s

6.0 m/s

0.17 m/s

Using a hammer to drive a nail, it is the reaction force that brings the motion of the hammer to a stop but the _______________ that drives the nail into the wood.

Answers

The correct answer for the question that is being presented above is this one: "action force." Using a hammer to drive a nail, it is the reaction force that brings the motion of the hammer to a stop but the action force that drives the nail into the wood.

Explanation:

The reaction force is what presents you drive because it acts on you. Newton's Third Law of Motion describes that forces perpetually come in action-reaction pairs. The Third Law states that for every action force, there is an identical and opposite reaction force. The ball exerts an equal and opposite force on the bat.

How can you describe the image formed by a plane mirror?

Answers

Look at yourself in a plane mirror and you see your image - it is upright. The image is located on the other side of the mirror since reflected rays diverge upon reflection; when mirrors produce images on the the opposite side of the mirror, the images are said to be virtual. the distance from the object to the mirror.
