What do astronomers mean by light pollution?
Margarita [4]

Answer:

a. Light pollution refers to light used for human activities that brightens the sky and hinders astronomical observations.

Explanation:

Light pollution is due to the excessive and misdirected use of artificial light. Light bulbs are often design in an incorrect way, since a great part of its light is not completely directed to the ground and an important percentage is emitted to the sky in where will be scattered and reflected back to ground by the particles in the atmosphere. That brings as an effect a sky glow, therefore the visibility of astronomical objects will be extremely reduce.  

Hence, professional astronomical research and amateur observations will be affected. Light pollution has a negative impact on bird migration at night and in the health of difference species, humans also.

Conclusion of experiment for determine the magnitude and direction of magnetic field of earth What we will write in our experime
Tema [17]

Answer:

The magnitude and direction of the earth's magnetic field is between the range of 0.25 to 0.65 Gauss considering the angle of the earth's north pole is eleven degrees.

Explanation:

The magnetic field or force of the earth is attributed to a dynamo effect but the electric charges are not constant. The origin of the field is believed to be from the molten metallic core and the earth's rotation.

The Force of the magnetic field is a function of the velocity or speed 'v' of the electric charges 'q' and the field itself 'B' at an angle of sin∅. That is,

F = vqBsin∅
