The correct option for the statement "The property of a star that relates to the amount of energy it is producing is its”.
Answer to Problem 4RAT
The correct option for the statement "The property of a star that relates to the amount of energy it is producing is its” option (a).
Explanation of Solution
Luminosity is the term that refers to the total energy released by a star into space. The luminosity of a star is determined using the Sun’s luminosity. It refers to the intrinsic brightness of a star based on the energy emitted by it. It does not give the measure of the brightness of a star as felt by an observer on the Earth.
Apparent brightness is defined as the brightness of a star as visible to our eyes. This quantity gives the brightness of a star as felt by an observer on the Earth.
Different colors of light are at different frequencies. The peak
Volume is the space occupied by a substance. The volume of a star does not have any relation to the energy emitted by it.
The mass is the property of a star, which determines the stages through which the star passes. It is a factor which gives an idea about the age of stars. The age of massive stars is lesser than the age of low mass stars.
Conclusion:
Therefore, the correct option for the statement "The property of a star that relates to the amount of energy it is producing is its" is option (a).

- A piece of metal is placed on top of a 2.0 - kg wooden block (mass density = 562 kg/m³) piece. UseArchimedes' principle to calculate the mass (in kg) of copper if the top of the wood surface is exactly at thewater's surface?arrow_forwardA filmmaker wants to achieve an interesting visual effect by filming a scene through a converging lens with a focal length of 50.0 m. The lens is placed betwen the camera and a horse, which canters toward the camera at a constant speed of 7.9 m/s. The camera starts rolling when the horse is 36.0 m from the lens. Find the average speed of the image of the horse (a) during the first 2.0 s after the camera starts rolling and (b) during the following 2.0 s.arrow_forwardAnswer the question (Physics)arrow_forward

- An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?arrow_forwardConcept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem.
