Answer:
θ = 4.092 °
Explanation:
Given that
Initial Angular speed ,ωi = 0.76 rad/s
Final angular speed ,ωf= 2.96 rad/s
The angular acceleration ,α = 1 rad/s²
We know that
ωf² = ωi ²+ 2 α θ
θ=Angle rotates
2.96² = 0.76²+ 2 x 1 x θ
Therefore the angle rotates by machine part will be 4.092 degrees.
θ = 4.092 °
Velocity = distance /time
acceleration = velocity / time
Answer: The five general characteristics of the nearest stars are the brightness, color, surface temperature, size, and mass.
Explanation:
The mass of a star can be described as being measured with our sun at 1 solar mass. One star can equal the size of our sun. There is one star named, Rigel, that is bigger than the Earths sun. Each star will vary in its density.
The size of the star, as stated above, can be the size of our sun and sometimes larger. The size is measured by solar radii.
Stars vary in their temp. They range anywhere from -273.15 degrees Celsius to 50,000 K. The temp is based on the Kelvin scale.
The stars brightness are always based on luminosity and magnitude.
The stars colors will vary and is based on the temperature of the surface of the star. Some stars are red in color, white in color, and some even have a bluish color.
