How are galaxies named?

Physics

choli [55]2 years ago
5 0

Answer:

Some galaxies are given descriptive names (e.g. "Andromeda", "Whirlpool") if they are particularly distinctive in location or appearance. But most galaxies are known from their designation in a catalogue. One of the earliest catalogues of objects in the sky was made by Charles Messier.

What is the term for the principal that an object in motion remains in motion until it is met by an outside force?
Papessa [141]

The term for the principal that an object in motion remains in motion until it is met by an outside force is called inertia

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force .This principal is named as inertia .

Every matter have inertia , a property to remain in that very position until unless it is been forced on them to change their position .

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true.

A vertically polarized light wave of intensity 1000 mW/m2 is coming toward you, out of the screen. After passing through this po
Bingel [31]

Answer:

The intensity is I  =  500 mW/m^2

Explanation:

From the question we are told that

    The  intensity of the unpolarized light is I_o  =  1000 \ m W  /m^2  =  1000 *10^{-3} \ W/m^2

Generally the intensity of the light emerging from the polarizer is  mathematically represented as

          I  =  \frac{I_o}{2}

substituting values

         I  =  \frac{1000 *10^{-3}}{2}

         I  = 500 *10^{-3} W/m^2

         I  =  500 mW/m^2
