- Three polarizing sheets are placed in a stack with the polarizing directions of the first and third perpendicular to each other. What angle should the polarizing direction of the middle sheet make with the polarizing direction of the first sheet to obtain maximum transmitted intensity when unpolarized light is incident on the stack? 0° 15° 30° 45° 60° 75° 90°What 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.Which of the following statements are TRUE about the Sun's spectrum, which is shown in this image? Brightness 2.5 3.5 0 200 Sun's Spectrum vs. Thermal Radiator of a single temperature T = 5777 K peak spectrum of Sun spectrum of T = 5777 K blackbody emission spectrum (continuum) absorption lines 400 600 800 1000 1200 1400 1600 1800 Wavelength (nanometres) 2000 The spectrum shows the presence of many sunspots. The overall shape is consistent with a continuous spectrum emitted by a blackbody. The spectrum shows that the Sun emits light of all colors equally, which is why we see it as white. The spectrum shows that the Sun emits some light in ultraviolet wavelengths. The spectrum peaks in infrared wavelengths.
- If the temperature at the centre of the sun is 15,000,000 K and the temperature of the photosphere is 5,800 K, what is the ratio of the temperature at the centre of the Sun compared to the photosphere? Express your final answer in the fully factorised form x : 1, where x is a number that you should determine to an appropriate number of significant figures and write it using scientific notation.62. Pressure of the Photosphere. The gas pressure of the photosphere changes substantially from its upper levels to its lower levels. Near the top of the photosphere, the temperature is about 4500 K and there are about 1.6 x 1016 gas particles per cubic centimeter. In the middle, the temperature is about 5800 K and there are about 1.0 x 10" gas particles per cubic centimeter. At the bottom of the photosphere, the temperature is about 7000 K and there are about 1.5 × 10" gas particles per cubic centimeter. Use the ideal gas law (Mathematical Insight 14.2) to compare the pressures of each of these layers; explain the reason for the trend that you find. How do these gas pressures compare with Earth's atmospheric pressure at sea level?1) What is thermal equilibrium? Is the Sun in thermal equilibrium? How do we know this? 2) In order to maintain thermal equilibrium, how much energy must the Sun generate every second?
- Assume that the solar wind causes the Sun to lose mass at a rate of 2 x 10’ kg/s. If you assume the wind is emitted a constant rate, estimate the time (in units of Gyr =Gigayears = 10° years) that it will take the entire Sun to evaporate via its solar wind emission. (Of course, the rate won't be constant throughout the lifetime of the Sun---this is just a rough estimate to understand the timescale associated with this process.) [Hint: you need to look up a number and do several unit conversions; this is a *rate* problem. Enter your answer as an integer or decimal, NOT in scientific notation.]Sunspots appear dark because they are A) hotter than the rest of the Sun's surface. B) more magnetic than the rest of the Sun's surface. C) cooler than the rest of the Sun's surface. D) None of the aboveWhy does nuclear fusion only take place in the Sun’s core?
