Answer:
Explanation:
Hello,
In this case, considering that the density is considered as the quotient of the mass and volume:
We can easily compute the mass by solving for it as follows:
Best regards.
I believe the correct order of words should be:
Counterclockwise
Crescent
Full
Half
Faces?
Waxing
Right
Waning
Left
I am not sure on faces, but I don't see any other words from the bank that would fit that description. Hope these are correct and hope I helped!
well the atomic number is 7 the number of protons is also equal to 7 .
hope this helps
Electromagnetic wave travels faster through air than metal.
Option A
<u>Explanation:</u>
There are different kinds of wave energy. The most significant are electromagnetic and mechanical waves. The mechanical waves propagate through the medium by transfer of energy by vibrating of particles in medium.
So, the more number of particles present in the medium, the more fast the mechanical wave can propagate. So the mechanical waves travel faster in metals consisting of more number of free charge carriers. But electromagnetic waves does not need any of the medium to propagate. So it can travel faster in air than in metals.
Global cooling was a hypothesis of the looming cooling of the Earth's surface and atmosphere that would take place over a period of substantial glaciation.
It emerged as a result of a drop of temperature during the period of 1940s and 1970s. After this it was realized that it is not a big threat as global warming.
On the other hand, Global warming is the rise in overall temperature of the atmosphere which is caused by greenhouse effect that is as a result of rise in the levels of greenhouse gas emissions such as CFCs and carbon dioxide.
Global warming is a present threat in the society world over with the rise in temperatures and climatic changes taking place, this is the reason why global warming replaced global cooling.
