Answer:
Defined below
Explanation:
Climate change is simply the long term change in the average weather patterns that are associated with the local, regional and global climates of the earth. Climate change is usually driven by human activities like burning of fossils; natural processes like cyclic ocean patterns; external factors like volcanic eruptions.
Answer:
Note that both of the falsifiable claims in this example happen to be true. The claim about Kennedy being the 35th President is falsifiable because it can be checked against historical records. The claim that Kennedy died from a bullet in his brain is falsifiable because it could have been shown false by the medical examiner. The remaining claims are not falsifiable: Statements that call on any type of supernatural being are by definition out of the realm of science. Similarly, a claim of something being "undetectable" could not be falsified, and a claim about what Kennedy would have done if he had lived is a conjecture that cannot be disproven.

Explanation:
Given that,
Initial velocity, u = 11.3 m/s
Angle above the horizontal, ![\theta=35^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D35%5E%7B%5Ccirc%7D)
Time of flight :
![t=\dfrac{2u\sin\theta}{g}\\\\t=\dfrac{2\times 11.3\times \sin(35)}{9.8}\\\\t=1.32\ s](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B2u%5Csin%5Ctheta%7D%7Bg%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B2%5Ctimes%2011.3%5Ctimes%20%5Csin%2835%29%7D%7B9.8%7D%5C%5C%5C%5Ct%3D1.32%5C%20s)
Horizontal distance traveled is given by :
x = ut
x = 11.3 m/s × 1.32 s
x = 14.916 m
Maximum height is given by :
![H=\dfrac{u^2\sin^2\theta}{2g}\\\\H=\dfrac{(11.3)^2\times \sin^2(35)}{2\times 9.8}\\\\H=2.14\ m](https://tex.z-dn.net/?f=H%3D%5Cdfrac%7Bu%5E2%5Csin%5E2%5Ctheta%7D%7B2g%7D%5C%5C%5C%5CH%3D%5Cdfrac%7B%2811.3%29%5E2%5Ctimes%20%5Csin%5E2%2835%29%7D%7B2%5Ctimes%209.8%7D%5C%5C%5C%5CH%3D2.14%5C%20m)
Hence, time of flight is 1.32 s, horizontal distance is 14.916 m and maximum height is 2.14 m.
False.
Protons have a charge of +1 and neutrons are neutral.
This would be true if neutrons was replaced with electrons.
Answer:
the correct one is 2
Explanation:
The emission and arcion spectra are similar, in the emission spectra a heated material emits photons for the internal transitions of the electrons, in the absorption spectrum the continuous emission of a lamp is absorbed at the energies that the material has transitions.
In our case the material is low early, so all the electrons are in their base states.
As the light beam has all wavelengths, those corresponding to the first emission of the material will be observed.
When reviewing the answers, the correct one is 2
