Answer: Earth's orbital path around the Sun</h2><h2>
</h2>
The <u>Ecliptic</u> refers to the orbit of the Earth around the Sun. Therefore, <u>for an observer on Earth it will be the apparent path of the Sun in the sky during the year, with respect to the "immobile background" of the other stars.</u>
<u />
It should be noted that the ecliptic plane (which is the same orbital plane of the Earth in its translation movement) is tilted with respect to the equator of the planet about 
approximately. This is due to the inclination of the Earth's axis.
Hence, the correct option is Earth's orbital path around the Sun.
<h2>
Option B is the correct answer.</h2>
Explanation:
Period of a spring mass arrangement is given by
where m is mass and k is spring constant.
So period of spring mass arrangement is independent of amplitude of motion.
Here amplitude changes from A to 2A.
Period for amplitude A is given by T.
Since period remains same for amplitude 2A also, the period is T.
Option B is the correct answer.
Answer:
685.6 J
Explanation:
The latent heat of vaporization of ammonia is
L = 1371.2 kJ/kg
mass of ammonia, m = 0.0005 Kg
Heat = mass x latent heat of vaporization
H = 0.0005 x 1371.2
H = 0.686 kJ
H = 685.6 J
Thus, the amount of heat required to vaporize the ammonia is 685.6 J.
The Kyoto Protocol, which limits emissions of greenhouse gases for developed nations, is an example of international Law
Explanation:
The Kyoto Protocol is named after a Japanese city in which it was executed in the year 1997 on 1st December.
The basic aim of the Kyoto Protocol is to reduce/Limit the emission of greenhouse gases which contributed to global warming
The Protocol was linked to the United Nations Framework Convention on Climate Change (UNFCCC)
The important factor that led to the failure of Kyoto's Protocol are deficiencies in the structure of the agreement, such as the exemption of developing countries from reductions requirements, or the lack of an effective emissions trading scheme
Answer:
11.106 Mev.
Explanation:
Sr⁸⁸ → Sr ⁸⁷ + ₀n¹
87.905612 86.908877 1.008664 ( atomic masses in amu )
mass defect = ( 86.908877 + 1.008664) - 87.905612 = .011929 amu.
Equivalent energy in MeV = .011929 x 931 = 11.106 MeV
