In addition to ozone, the four other greenhouse gases or groups of greenhouse gases are included in nearly all the climate models are Carbon dioxide, water vapor, and methane, nitrous oxide.
Carbon dioxide, absorbs energy at a variety of wavelengths, a range that overlaps with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the ‘greenhouse effect.’
As methane is emitted into the air, it reacts in several ways. It reacts and after oxidization methane forms water vapor and carbon dioxide. So, not only does methane contribute to global warming directly but also, indirectly through the release of carbon dioxide.
Nitrous oxide enhances the greenhouse effect by capturing reradiated infrared radiation from the Earth’s surface and subsequently warming the troposphere . It is chemically inert in the troposphere and stays in the troposphere for about 120 years before moving into the stratosphere where it ultimately leads to destruction of stratospheric ozone.
Water vapor does absorb longwave radiation and radiates it back to the surface, thus contributing to warming.

Answer: 45.1N
Explanation:
Answer: 45.1N
Explanation:
The work done in the block is equal to change in energy is the system. We then go ahead to calculate W with the given values of initial and final speed.
W= Ef - Ei
W= 1/2MVf² - 1/2MVi²
W= 1/2M (Vf² - Vi²)
W= 1/2 * 41 (6²-5²)
W= 1/2 * 41 * 11
W= 225.5J
We note the definition of work and solve for F.
Taking into cognizance the displacement we have been given in the question. We then have
F = W/x
F = 225.5/5
F = 45.1N
Answer:
Explanation:
work done by gravitational force during fall of distance d = mgd
work done by drag = w ( let )
mgd - w = 1/2 m v²
w = m g d - 1/2 m v²
so work done by drag force
= m g d - 1/2 m v²
b ) when terminal velocity is reached , drag force = mg
power supplied by drag force = force x velocity
= mg x v
P_d = mgv
If gold gets hot enough, and melts, then this is a <u>physical change</u><u>.</u>
Melting is a physical change. Keep in mind that temperature and melting are both physical properties.
We know that: 1 L = 100 cL. Or 1 cL = 0.01 L. Then we will make the conversion: 34.9 cL = 34.9 / 100 L = 0.349 L. Also: 1 hL = 100 L. 0.349 L = 0.349 / 100 hL = 0.00349 hL. This can be also written as: 3.49 * 10^(-3) hL ( in the scientific notation ). Answer: 3.49 cL = 0.00349 <span>hL </span>
