How do you find the altitude and azimuth of a star? Celestial Coordinates: In order to describe the position of a star, a planet or any other astronomical objects, we need to use a well defined coordinate system. They might be a horizontal system which uses azimuth angle and altitude as ...
And what will happen to Earth and its inhabitants when the sun dies?) Let's look at the parts of our nearest star, find out how it makes light and heat and explore its major features. Sun Facts Average distance from Earth: 93 million miles (150 million km) Radius: 432,000 miles (...
When you buy a pair of cheap sunglasses, you often give up all of these benefits and can even make things worse. For example, if your sunglasses offer no UV protection, you increase your exposure to UV rays. The cheap sunglasses block some of the light, causing your iris to open to al...
how do I find the planet radius Re (earth) and Rj (Jupiter)Show transcribed image text There are 2 steps to solve this one. Solution Share Step 1 To calculate the mass and radius of the planet we can use the following equations: Mass = (4 * pi * Brightness_drop * Star_...
[2] Neutron stars have a radius on the order of 10 kilometres (6.2 mi) and a mass of about 1.4 solar masses.[3] They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of...

Let's say I want to create a circle with a radius of 30 mm. Ok... so I... 1. Create a straight path (using the pen tool?) of 30 mm starting at 0,0 (from 0,0 to 0,30). 2. Select the 0,0 (with the direct selection tool?) extreme of the straight path (only on...
First, I use transit-finder.com to find out where and when transits are visible within a radius of several hundreds of km around my home. I also have to consult the weather forecast during the days before the event, to assess the probability of a clear sky and determine the best area ...
In addition to short distances, cells need a large surface area for diffusion to be efficient. Most cells are spherical or cuboidal. Let's look at an example of a spherical cell with a radius(r). The volume of a sphere is given by the formulaV = 4/3 r3, while the surface area is...
