[OU.03] What is the best method to increase the accuracy of the parallax measurement of star distances?

Physics
1 answer:
Korolek [52]3 years ago
5 0

Answer: Trigonometric or Stellar Parallax

Explanation:

Whenever a star is too far away to measure its parallax, astronomers do match its color and spectrum to one of the standard candles and determine its intrinsic brightness.

Comparing this to its apparent brightness, they can get a good measure of its distance by applying the 1/r^2 rule.

Astronomers estimate the distance  of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. They measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

How do i find the number of leptons in an atom??
Serjik [45]

Answer:

In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.

What resistance would produce a current of 200A with a potiential difference of 200V?
viktelen [127]
Aw, I hate physics, is this on Apex?

Resistance can be calculated with the information given in the question.
Equation for Resistance: R = V/I
V (voltage) = 200 Volts
I (current) = 200 Amps

So 200 divided by 200 = freaking 1

Answer: R = 1 (ohms)

Hope this Helps!
