Halogens are highly reactive nonmetal elements in group 17 of the periodic table. ... Halogens are among the most reactive of all elements. They have seven valence electrons, so they are very “eager” to gain one electron to have a full outer energy level.
Hi there!
In this instance, the centripetal force experienced by the moon is equivalent to the gravitational force.
Thus:
Centripetal acceleration, according to Newton's Second Law:
Therefore:
Explanation:
It is given that,
Mas of the object, m = 6 kg
It is lifted through a distance, h = 5.25 m
Tension in the string, T = 80 N
(a) By considering the free body diagram of the object, the forces can be equated as :
Work done by tension, 
(b) Work done by gravity, 
(c) Let v is the final speed of the object and u = 0
v = 5.91 m/s
Hence, this is the required solution.
Answer:
Radio waves have frequencies as high as 300 gigahertz(GHz)to as low as 30 hertz(Hz).At 300 GHz the corresponding wavelength is 1mm and at 30Hz is 10,000 km
I have two different answers. One is what the shcool most likely wants you to think and the other is the truth.
School: The waters could become more or less salty. Warm water is less dense than cold water so it will sit on top of cold water. It would very bad for plants because not all plants can live in such saltiness conditions.
Global Warming isn't a thing. It's fake, scientist have lied about it, and it's entirely false. The salt from the ocean comes from the constant bashing of ocean waves on the rocks. "Warm water is less dense than cold water so it will sit on top of cold water." is true, but that doesn't mean the oceans will be more salty if it is warmer, that just says how dense the salt and water is. it can be warmer or colder doesn't matter.
Hope it helps please let me know.
