Correct answer is option A.
Tropopause, Stratopause and Mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. All layers of atmosphere observe abrupt change in temperature. Tropopause is the boundary between Troposphere and Stratosphere. Stratopause is the boundary between Stratosphere and Mesosphere. Mesopause is the boundary between Mesosphere and Thermosphere. These all boundaries are ranges between altitude of 0 to 80 km.
Answer:
Explanation:
Period of oscillation ∝ √ m
So period of oscillation is proportional to square root of mass
So when mass increases , period too will be increased . But the total energy will remain the same as per conservation of energy.
Hence option ( D) is the correct answer.
Elastic collision is when kinetic energy before = kinetic energy after
Ek= 1/2mv^2
total before
Ek=1/2(2)(2.2^2) = 4.84 J
total after
Ek= 1/2(2+4)(v^2) = 3v^2
Before = after
4.84=3v^2 | divide by 3
121/75 = v^2 | square root both sides
v=1.27 m/s
Answer: well if it isnt moving, then there would not be any potentiol energy. Sothe answer is 0. I hope this helps :) Thank you. Plz mark brainliest.
Explanation:
The most abundant gas in Earth’s atmosphere is Nitrogen (78% of the atmosphere), followed by Oxygen (21%), the gas we need to live, which is also needed to burn wood and fuel.
The third-most abundant gas is Argon (0.93%).
The fourth most abundant gas is Carbon Dioxide ... the amount in the atmosphere is very small, making up just 0.04% of the atmosphere, but it is very important because plants use it to make simple sugars.
Another important gas is water vapor, which condenses in the atmosphere to form clouds and then rain.
The atmosphere also holds trace amounts of Neon, Helium, Methane, Krypton and Hydrogen.
