What is the angular diameter of a star like the sun located 6 ly from Earth?
(I have the formula I need to determine this answer, but I am looking for some guidance on how to enter this equation in my calculator to arrive at the final answer. Can anyone help?)
Homework Answers
The angular diameter is calculated using the following formula
The diameter of the sun like star is
Distance from the earth of this star is
Now putting these values in the formula

Tau Ceti is a star that is located 11.753 ly away. There
is a planet orbiting this star with an orbital radius of 0.538 AU
(AU stands for astronimcal unit - the average distance between
Earth & the Sun). Fill in the table below by determining the
minimum diameter the objective of a telescope would need to be in
order to resolve the planet from the star at the stated
wavelengths. 1 ly = 9.461 × 1015 m & 1...
What is the maximum angular diameter of Ceres in seconds of arc as seen from Earth?...
What is the maximum angular diameter of Ceres in seconds of arc as seen from Earth? (Hints: Use the small-angle formula; angular size in seconds of arc = 206,265 x physical size/distance; Ceres's orbital radius is 413.9 million km; and its diameter is 965 km. Note that the Earth is about 149.6 million km from the sun.) Can details be seen on the surface of Ceres with a 100 inch simple mirror reflecting telescope?

5. Stellar Parallax and a Parsec (15 pts.) A star with l arcsecond parallax angle (0) it is definedto be 1 parsec away. Let's calculate the value of a parsec. Examine the diagram below. When viewed from the two positions (3 months apart), the star's position shifts by the angle e. Sun Earth Star (a) What is the distance (a) in km?

Figure 2 shows observations of the spectrum of another star, like the Sun but more distant, as seen from the Earth over the course of a year. The wavelength range shown is the same tiny portion of the spectrum shown in the bottom panel of the earlier figure, and the same two prominent iron lines are seen. From laboratory measurements of such atoms, it is known that the wavelengths of these two lines are hemit - 633.53 for the shorter...

Today, the Moon’s orbit around
Earth has a semi-major axis of a=384,400 km and an orbital period
of 27.32166 days.
a. The Moon slowly moves outward due to tidal braking of the
Earth’s rotation, and at some future date the Moon will have an
orbital period of 47 days. Compute the semi-major axis of the
Moon’s orbit at this future date (express your answer in
kilometers).
semi-major axis = 5.5*10^5 km
b. Today, the Moon has an angular diameter of...

In trying to apply my knowledge in the real world, I am trying to create a realistic retirement schedule. However, I am running into difficulties using both a financial calculator as well as our equations from class in doing this. I am trying to do the following: plan a retirement schedule between the ages of 25 and 70, in which I would deposit 20% of my income each year. The income starts at 80,000 with an annual growth rate of...

Example 1 A star undergoes some mode of oscillation. Scientists/engineers have hypothesized that the oscillation frequency (cycles per second), o, is dependent on the density p and the radius R and the gravitational constant G which appears in Newton's law of universal gravitation. If you are not familiar with the gravitational constant, read the section on mass and weight in Chapter 4 (Dimensions/units) of the text. Therefore, w has dimensions (T), and P, R, Gare the governing parameters, with dimensions...
