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.

Answer : a. Community
Allows a system to be accessible by a group of organizations. It can be shared between several organizations. It may be managed by organizations or by the third party.
This should be chosen by Ryan, since this computing model is cost effective and best to share among companies and organizations.
Other options explained:
-Software model is accessible via a browser and multiple users can use it.

Answer:
3.75 × 10⁻⁸ N
Explanation:
Given:
Intensity of the electromagnetic wave, I = 150 W/m²
Sides of the board = 25 cm (= 0.25 m) and 30 cm (= 0.30 m)
therefore,
the area of the rectangular box, A = 0.25 × 0.30 = 0.075 m²
Now,
force exerted on the card by the radiation, F = 
here,
C is the speed of the light = 3 × 10⁸ m/s
on substituting the respective values, we get
F = 
or
F = 3.75 × 10⁻⁸ N
