Ocean Currents is the factor that determines the air temperature in coastal regions having same latitude.
<u>Explanation:</u>
There are factors that use to determine air temperature. They are latitude, altitude, region, water current, etc and it is based on the combination of water, air, and land.
If two coastal regions situated in the same latitude means they are not in the same region. Another city can be in the same latitude but in longitude. All the coastal regions don't have the same air temperature.
The air temperature in coastal regions can measured by the Ocean Current. A hypothesis of using cold water and warm water use to determine the air temperature.
The speed of the particle when it enters the magnetic-field region is 120,000 m/s.
<h3>
Speed of the particle</h3>
Magnetic force on the particle is given as;
F = qvB
where;
- q is magnitude of the charge
- v is speed of the particle
- B is magnetic field strength
From Newton's second law, force on an object is given as;
F = ma
where;
- m is mass of the particle
- a is acceleration
ma = qvB
v = ma/qB
v = (3 x 10⁻² x 12)/(3 x 10⁻⁶ x 1)
v = 120,000 m/s
Thus, the speed of the particle when it enters the magnetic-field region is 120,000 m/s.
