- Chapter #8, Question #2: Use eqn. 8.4 (F = σT4) to show why the total flux of solar radiant energy is about 105 times greater than that from the Earth.1. As shown in Fig. 1 the candle is at the center of curvature of the concave mirror, whose focal length is 10.0 cm. The converging lens has a focal length of 32.0 cm and is 85.0 cm to the right of the candle. The candle is viewed looking through the lens from the right. The lens forms two images of the candle. The first is formed by light passing directly through the lens. The second image is formed from the light that goes from the candle to the mirror, is reflected, and then passes through the lens. (a) For each of these two images, draw a principal-ray diagram that locates the image. (b) For each image, answer the following questions: (i) Where is the image? (* (ii) Is the image real or virtual? ) (iii) Is the image erect or inverted with respect to the original object? it K- -85.0 cm- Fig. 1What is the name of the specific nuclear fusion process that dominates energy production in the core of the Sun and gives a brief description of how it works. What I'm looking for in this description is what is the basic premise behind nuclear fusion and what is going into this specific fusion reaction and what comes out of it.
- The velocity of the solar wind is roughly 400 km/s. How long does it take to travel from the sun to Earth?Fusion only occurs in the solar core. Assuming that 10% of the Sun’s total mass is available to participate in fusion, how long can the Sun continue hydrogen fusion until all available mass is used up? (express your answer in years)This picture shows a radio meter. It is designed to be placed in a sunny window. One side of each thin blade of the radio meter is painted black, and the other side is painted white. The suns rays strike the blades, in the device begins to spin. The device is powered by which kind of energy?(2009)
