It has a diameter of about 78 billion miles. For perspective, that's about 40% the size of our solar system, according to some estimates. And it's estimated to be about 21 billion times the mass of our sun. So there you have it, black holes can be millions of times larger than suns and planets or as small as a city.
For number 3, I believe it is B, as people subconsciously get the name Levi's into their head. When people say I want to go to Levi's stadium for a game, they connect it with good thoughts, and next time they want to get jeans they might think, what jean brand do I know, and think of Levi's.
For number 4, I believe it is D. A is untrue, and B and C have nothing to do with the exchange of information between consumers.
For number 5, it is C, Monopoly. Monopolies are when 1 company is the only one who sells a particular good or service. There are some monopolies, but most of them are by federal agencies and consumers most likely do not want to choose for those services.
For number 6, I believe it is A, right to consumer education. I originally thought it might be B, however, when I looked up B, there was no such law, and what came up is the right to consumer education. I am not 100% sure on this one, but your best bet is A I think.
Hope this helps!
A red light means to stop. If you are turning from a two-way road or onto a two-way road, then you are NOT allowed to reverse your car If you can't do it
Red is typically used to indicate danger or warning, and on traffic lights, it indicates a potential hazard ahead and, as a result, serves as a signal for drivers to stop. If the traffic light turns red while you are already at a junction, you must move swiftly to the opposite side to avoid a potential accident with oncoming traffic.
If the traffic light has turned red as you approach the junction and you are just entering it, you must stop. Unless there is a sign clearly telling you not to turn left at the red light, you may do so. Give way to people and cars coming from other directions when turning.

A sample of an ideal gas is heated, and its kelvin temperature doubles. The average speed of the molecules in the sample will increases by a factor of
The root-mean square (RMS) velocity is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path.
Root mean square speed is a statistical measurement of speed.
The root mean square speed can be calculated as : V1 : 
if temperature becomes double
let T1 is initial temperature
So , T2 = 2 * T1
now ,
Root mean square speed will be (V2) = 
=
* 
=
V1
Thus when temperature becomes double, the root mean square speed increases by a factor of
