Answer should be the earth
Answer:
276.5 m/s^2
Explanation:
The initial angular velocity of the turbine is

The length of the blade is
r = 17.9 m
So the centripetal acceleration is given by

At the instant t = 0,

So the centripetal acceleration of the tip of the blades is

Water because the light is able to enter the water and allow heat to enter faster.
I think the correct answer from the choices listed above would be the last option. It is the chemicals in the core of the star that cannot be determined from the spectrum of a star. Spectrum shows the different classification of the stars depending on their spectral characteristics. It usually involves the light, the wavelength and the distance.
