If the net force on a chair is 6 newtons to the right, what will occur? *
Tatiana [17]

Answer:

The chair will accelerate to the right.

Explanation:

As we know by Newton's Law that when some net unbalanced force is exerted on the system then it will accelerate in the direction of force and the equation is given as

F = ma

now we know that 6 N force is exerted on the chair towards right

So here the chair will accelerate in the direction of net force

so correct answer is given as

The chair will accelerate to the right.

a. Of the three experiments that are used to confirm the Big Bang theory, which is the most interesting to you and why?
HACTEHA [7]

Answer:

Explained

Explanation:

Big Bang happened about 13.7 billion years ago. It is most accepted theory of universe creation. Several experiments have confirmed the happening of big bang back then, in promising way. One of this experiment is the red shift experiment. A scientist named Edwin Hubble tried to study the spectrum of stars. He made a shocking revelation that universe is rushing outwards in all directions. Light travelling away registers on the red side. He observed that the distance stars showed red shift in accelerated manner. If the universe is accelerating that means, at one point it would have been smaller, in fact it was as small as an atom, some how it exploded and lead to formation of the expanding universe.

What is not a similarity between mars and earth today?
eduard

Answer:

Mars and Earth are two of the planets of the solar system. Some of the ways in which Mars is different from Earth are as follows-

  • The size of the earth is bigger than Mars as Earth has a radius of nearly 6400 km, whereas Mars has a radius of about 3400 km.
  • The atmosphere of earth is primarily comprised of gases such as 78% of Nitrogen (N₂), 21% of Oxygen (O₂), 0.03% of Carbon dioxide (CO₂), and 0.9% of Argon (Ar), whereas the atmosphere of Mars is mainly comprised of 95% of CO₂, 3% of molecular N₂, and 2% of Ar.
  • The surface gravity also marks a contrasting difference as on Mars, the gravity at the surface is only about 38%, in comparison to the gravity at the earth's surface.
