he spectrum of a star is collected and we find the absorption line of Hydrogen-Alpha (the deepest absorption line of hydrogen in the visible part of the electromagnetic spectrum) to be observed at 656.5 nm instead of 656.3 nm as measured in a lab here on Ear

consider plutos diameter and mass. (2374)km & (1.303E22kg) and day which is 6.4 dayz long. FIND: 1. please elaborate how would you get the answer to the escappe vel0city from plut0. 2. we would need to find the minimum energy required for an aircraft or ship of some sort with mass (525kg) to escape this planet.. 3. we would also need to find the t0tal energy for a complete orbit around the planet with an airship with a same mass (525) and an altitude of 224 km

The astronomer claims that the frequency, f, of a vibrating star depends on its radius R, density r and gravitational constant G. Use dimensional analysis to find this dependence, if f is measured in s-1 and the units of G are L3/(MT2).

Show work. For the following: A parsec is a distance equal to 3.26 light years. The speed of light is 2.998 x 10°m/s. A nght year is a unit of distance equal to the distance light travels in one year. The brightest star in the night sky is Sirius, (Not the radio station) is 2.63 parsecs away. (1km30.621miles, 365d-1yr) How many miles away is this star?

What will be the energy associated with a blue photon (in Joules), if the frequency of the blue light is 650 THz (Terahertz (THz); 1 Tera – 1012y? [Hint: Use Planck's cquation: E = hf to calculate the photon energy! h - Planck's constant – 6,63 × 10-4 Js – 4.14 ×1015 eVs] A. 650×1012 J B. 6.5×10° J C. 4.3x1015 J D. 4.3×10-19 J E. 4.3x1019 J

In Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2. Whenever the individual value you are looking at falls within the range of values specified on the flow chart, mark the cell to the right of the value with a Y for…

For a star with surface temperature 5,100 K, what is the peak frequency of light from the sun? Write your answer in THz (1012 Hz), to zero decimal places. Take the speed of light to be c=3 x 108 m/s.

I attempted to answer this question and I'm not sure what I am doing wrong. My formula says A.S. = 206265 (separation/distance from observer) I know to convert to the same units, so I ended up with 80 Million Km being 8 x 10 ^ -6 LY Could you please explain each step especially for the part that I got wrong for both A and B?

Using the center-of-mass equations or the Center of Mass Calculator (under Binary-Star Basics, above), you will investigate a specific binary-star system. Assume that Star 1 has m₁ = 3.4 solar masses, Star 2 has m₂ = 1.4 solar masses, and the total separation of the two (R) is 52 AU. (One AU is Earth's average distance from the Sun.) (a)What is the distance, d₁, (in AU) from Star 1 to the center of mass? AU (b)What is the distance, d2, (in AU) from Star 2 to the center of mass? AU
