Answer:

  t = 22.44 s

Explanation:

The acceleration of the station is centripetal which has the formula

         a = v² / r

linear and angular velocity are related

         v = w² r

as they indicate that the acceleration is equal to the acceleration of gravity

         g = w² r

         w = \sqrt{  \frac{g}{r} }

         

let's calculate

         w = \sqrt{ \frac{9.8}{ 125} }

         w = 0.28 rad / s

to calculate the time use us

          w = θ / t

in a complete revolution θ = 2pi

          t = θ / w

let's calculate

          t = 2π / 0, 28

          t = 22.44 s

How to measure the external diameter of a sphere
DanielleElmas [232]
Sphere is that the circular objects in the two dimensional space (1) circle
(2) disk. Two dimensional space is a set of points and the distance of that point,The two points of Sphere that length and center.
Sphere can constructed as the named of surface form circle about any diameter. circle is the special type of the revolution replacing the circle,
sphere is the distance r is the radius of the ball and circle is the center of mathematical ball,as the center and the radius of the sphere is to respectively.
The ball and sphere has not be maintained mathematical references as a solid references. A sphere of any radius is centered at the number of zero.

An electromagnetic wave has a wavelength of 1.3m what is the frequency of wave
larisa86 [58]
V = f * wavelength
as we know electromagnetic wave has speed equal to light, so

3 * 10^8 = f * 1.3
f = 2.3 * 10^8 hertz
f = 230 mega hertz
