Answer:
A - gamma-ray telescopes
Explanation:
Gamma rays have the shortest wavelengths of the electromagnetic spectrum, and are blocked by Earth's atmosphere. Therefore, gamma ray telescopes will be used to observe them. Hope this helps :)
Answer:
The capacitance is 1.75 nF
Explanation:
From the question we are given that
The inner radius is
The outer radius is 000.1
Length of the capacitor is L = 1m
The dielectric constant is Di = 2
The dielectric constant is Di2 = 4
Generally the capacitance of a capacitor can be mathematically represented as
1.75nF
CO2 and N2O keep the energy that gets to Earth from the sun inside the atmosphere. Without greenhouse gases, our planet would be too cold. But due to the recent increase in greenhouse gases, more energy released from the sun is contained in the Earth, heating it up.
I think, it must be a chemical. Because the fire is a chemical reaction. So, the chemical energy converted to heat energy.
