The centripetal acceleration of an object is given by the relation,
![Ac =V^2/R](https://tex.z-dn.net/?f=Ac%20%3DV%5E2%2FR)
where Ac = centripetal acceleration =
R = radius of rotation = 15 m
V = speed of astronaut
Hence, ![\frac{V^2}{15} =98](https://tex.z-dn.net/?f=%5Cfrac%7BV%5E2%7D%7B15%7D%20%3D98)
solving this we get, V = 38.34 m/s
The answer for this is b 3.500.000j
I don’t know sorry then ya soo
Electromagnetic wave allows us to control television with a remote control.
This electromagnetic wave is invisible.
Infrared is that electromagnetic wave that is used to control television using remote control.
