enot [183]

Answer:

60°

Explanation:

Formula

360/n (if the number is an odd number) or

360/n-1 (if the number is even) (to arrive at an odd number)

SO. 5 is an odd number but not a multiple of 360, so we will use 6 an even number.

360/60-1

360/60=6 images

6-1 =5 images

Thus. the images formed will be 5.

bogdanovich [222]

Answer:

The speed is 0.97 c.

Explanation:

Given that,

Dilated time t'= 50.0 years

Rest time t = 13.0 years

We need to calculate the speed

Using formula of time dilation

t'=\dfrac{t}{\sqrt{1-\dfrac{v^2}{c^2}}}

Where, t' = change in time

t = rest time

v = velocity

c = speed of light

Put the value into the formula

50.0=\dfrac{13.0}{\sqrt{1-\dfrac{v^2}{(3\times10^{8})^2}}}

v^2=\dfrac{(13)^2\times(c)^2-(c)^2\times50^2}{50^2}

v^2= 0.9324c^2

v=0.97c

Hence, The speed is 0.97 c.
