Explanation:
The wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

Answer:
B) krypton
Explanation:
Electron configuration of Br: [Ar] 3d10 4s2 4p5
Since we have the bromide ion with a negative charge, Br's atom acquired an electron and therefore another electron is added to the electronic configuration
.
Electron configuration of Br-: [Ar] 3d10 4s2 4p6
And now this electronic configuration coincides with that of Krypton as we see below
:
Electron configuration of Kr: [Ar] 3d10 4s2 4p6

Answer:
v = 16.58 m/s
Explanation:
Given that,
Mass of a bird, m = 1.6 kg
Kinetic energy of the bird, K = 220 J
We need to find the speed of the bird. The formula for the kinetic energy is given by :
Where
v is the speed of the bird
So,
Put all the values,
So, the speed of the bird is equal to 16.58 m/s.
