The surface rich that keep the world together. When they hit they create volcanoes and earthquakes
To make laws while other laws are in the making of others
Answer: 4.5 light years
Example;Lets say that in the dinosaur days there was a star that exploded.
after 8 light years we would see it now. (now as in 2020) So thats why 4.5
light years is more then 150 million kilometers.
Answer:
So the wavelength of light is 1015.7 nm
Explanation:
From Wein's displacement law, we can write the following formula;
here,
is the wavelength of maximum radiation in meters
T is the absolute temperature (in Kelvin) for maximum radiation
K is the constant has a value of 
Given here, T = 2853 K
And we need to find 
Putting the values in formula
