Answer:
V = V₀ / 5
Step-by-step explanation:
At rest V₀ is volume measured of a cube
When an observer measures it at high speed ( 0.98*c ) the length he measures from outside, if he can looks and measures the two points start and ending points of the parallel edge simultaneously, is shorther ( such effect is known as Lorentz contraction. In this particular case problem statement give γ ≈ 5
γ = 1 / √( 1 - v²/c²) γ = 1 / √1 -( 0.98)c²/c² γ = 1 /√1-0,9604
γ = 1 /√ 1 - 0.9604 γ = 1 /√0.0396 γ ≈ 5
As the contraction only occur in the sense of the movement then the volume of the cube would be
V = (edge)²* (edge/5) or V = V₀ / 5
Answer:
(a) After 5 years what will be his age?
"5 + y" years old
(b) What was his age 6 years back?
"y - 6" years old
(c) His grandfather‘s age is 5 times his age, What is the age of grandfather?
"5y" years old
(d) His father’s age is 6 years more than 3 times his age. What is his father’s age?
"6 + 3y" years old
Note: Ignore the quotation marks, ""
Second option: down on the left, down on the right.
Clearly when x is bigger than one the term -x^38 will dominate the result.
When absolute value of x grows, x^38 becomes a larger positive number and - x^38 a larger negative number. Then both ends of the function tend to negative infinity.
Answer: 
Step-by-step explanation:
The triangle CDE is shown in the image attached.
The formula for calculate the distance between two points is:
Then, we can calculate the lenght of each side of the triangle:
Therefore, the perimeter is:
