<span>Freezing involves the decrease in value of latent heat by 80 Cal/gm and a change of state from the Liquid phase to the solid phase.
So, in short, Fill in the blank as follows:
1st blank = Release/decrease
2nd blank = Liquid
Hope this helps!

Because dark line spectra result from passing white light through ionized gasses and plasmas, which is what the atmosphere of stars are made of. These frequencies are scattered by the star's atmosphere as it leaves the surface (photosphere) of the star, and don't make it to earth.
Answer:
Yes it is matter
Explanation:
In physics, usually the word "electricity" isn't really used. "Electric current" is more common, and is defined as the flow of charges, where the charges are held by particles (electrons). Electrons have mass, so they are definitely matter.
Answer:
108.8 m /s
θ = 21°
Explanation:
Centripetal acceleration = ω² R
=( 13 )² x .602
= 101.74 m/s²
tangential acceleration a_t = angular acceleration x R
= 64.1 x .602
= 38.58 m /s²
Total acceleration R
R² = ( 101.74 )² + ( 38.58 )²
R = 108.8 m /s
angle required be θ
Tanθ = tangential accn / radial accn
= 38.58 / 101.74
θ = 21°
True.
Explanation:
Earths tilted axis causes the seasons. Different parts of the earth receive the suns most direct rays. So when The north tilts towards the sun, it is summer in the northern hemisphere. Meaning when south tilts towards the sun, it’s winter in the northern hemisphere.
