Answer:
Forms over water, warm humid air mass, it's a polar air mass
Explanation: I think that's right sorry if it's not..

Answer:
The distance is 
.
Explanation:
Given that,
Time 
The velocity is no more than a 14 % error in the speed of light.
So,
Velocity 
We need to calculate the distance
Using formula of speed
Where, v = speed
d = distance
t = time
Put the value into the formula
We know that,
The one side distance d' is
Hence, The distance is .
Answer:
Explanation:
The refractive index of a medium is given by the following formula:
where,
η = refractive index = 1.5
= angle of incidence = ?
= angle of refraction = 15°
Therefore,
Answer:
The lowest mass that an object can have to be considered a star is 0.08 solar masses.
Explanation:
A star is get when it reaches the necessary temperature in its core to nuclear reaction began.
A Nuclear reaction is the fusion of lighter elements into heavier elements.
In stars there is an equilibrium between two forces, the force of gravity in the inward direction due to its own mass and the radiation pressure in the upward direction as a consequence of the nuclear reaction in its core, which is known as hydrostatic equilibrium.
Therefore, the mass of the star must be enough to the force of gravity act in the inward direction, which leads to the increase in pressure, density and of course temperature in the core, allowing the nuclear reaction to begin.
Hence, the lowest mass that an object can have to be consider a star is 0.08 solar masses.
