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
Recognize the difference of 2 perfect squares
remember
a²-b²=(a+b)(a-b)
9y⁴=(3y²)²
1=1²
9y⁴-1=(3y²)²-(1)²=(3y²+1)(3y²-1)
if we wanted to force a factor again
(3y²+1)(y√3+1)(y√3-1)
Answer:
$70.56 - 12 pounds of popcorn kernels.
Step-by-step explanation:
$5.88 - 1 pound
(x12) (x12)
$70.56 - 12 pounds
Answer:
Expose both of left side and right side.
For example: on the left side: 2(x+6) = 2x + 6.
For the first one. The complement is you subtract 90-51 = 39
The second one the supplement is 180-61= 119
