URGENT need answer quick
beks73 [17]

Answer:

Part A: x = 4.

Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.

Answer:

You are at the top of the Empire State Building on the 102nd floor, which is located 373 m above the ground when your favorite superhero flies over the building parallel to the ground at 70.0% the speed of light.

You have never seen your favorite superhero in real life. Out of curiosity you calculate her height to be 1.57 mm . If the superhero landed next to you, how tall would she be when standing?

Step-by-step explanation:

so this problem is from Einstein's special theory of relativity about length contraction.

the formula is given by:

L'=L\sqrt{1-\beta^2 }

where \beta =v/c

c is speed of light c=3*10^8 m/s and v is velocity of object.

L is called proper length. L' is length that the observer measure in moving frame.

here velocity of object is 70% speed of light. i.e   v=209 854 721 m / s

so L=1.57 m

putting all values

L'= 1.57m \sqrt{1-(\frac{209854721}{3*10^8})^2 } \\\\L'=1.12m
