True, scientists often talk to each other to figure out if their results were similar and what they could have done better.
Although, talking to other scientists does have risks, other scientists could copy your work and further better it.
So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol
Answer:
5.77×10¹⁰ m
Explanation:
From the question,
Applying
Kepler's third law
P² = d³...................... Equation 1
Where P = Planet's period, d = distance between the center of the planet and the sun.
make d the subject of the formula n equation 1
d = ![\sqrt[3]{P^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BP%5E%7B2%7D%20%20%7D)
.................. Equation 2
Given: P = 0.24 sidereal.
Substitute the value of P into equation 2
d = ![\sqrt[3]{0.24^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B0.24%5E%7B2%7D%20%7D)
d = 0.386 Au
d = 0.386×1.496×10¹¹
d = 5.77×10¹⁰ m
Answer:
it is option 3
Explanation:
because as red shift occurs when object in a space is far from us, so many of the stars we know will be seen in red shift because they are far from us by 20 years the most of the starts we see will be in red shift
Answer: Light is a form of electromagnetic radiation because it has the ability to travel from one type of medium to another and can also carry some energy along with it. A light wave has two components, namely the electric field component as well as the magnetic field component that are both perpendicular to the propagating direction.
The visible light lies between the ultraviolet and the infrared lights, with wavelength from 400 nm to 700 nm respectively. This is collectively known as the visible spectrum of light.
