LenKa [72]

Answer:

<h3>d = 8.6</h3><h3>d = √74</h3>

Step-by-step explanation:

A (8, 2) = (x_1 ,y_1)\\ B(3,9) = (x_2,y_2)\\\\d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d =\sqrt{\left(3-8\right)^2+\left(9-2\right)^2}\\\\d=\sqrt{(5)^2+(7)^2}\\\\d=\sqrt{25+49}\\\\d=\sqrt{74}\\\\d = 8.6023\\\\d = 8.6

Gwar [14]

Answer:

a) t₀ =  1.73205 s

b) 1.0 C

Step-by-step explanation:

(A)

The time dilation (t) observed by an observer at rest relative to the time (t₀) measured by observer in motion is;

t = \frac{t_0}{\sqrt{1 - \frac{V^2}{C^2}}}

t_0 = t \sqrt{1 - \frac{V^2}{C^2}} time measured by captain

⇒ t_0 = 2.0 \sqrt{1 - \frac{0.5^2C^2}{C^2}}             V = 0.5 c

⇒ t₀ =  1.73205 s

(B)

Speed of the light never exceeds by its real value. The speed of the light in any frame of reference is constant.

∵ It will be "1.0C" or just "C"

Answer:

Definitely

Step-by-step explanation:

In order to completely surround a circle, you need six circles to do that while here in the question it is mentioned that currently there are only five circles surrounding the circle, hence there is enough room to easily fit one more circle.

I just hope that you are satisfied with the answer, Best of Luck.
