Answer:<u> Canis Major Dwarf Galaxy</u>

<u />

Explanation:

Distance Information

The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.

The car has a mass of 1200kg. The car has a forward force of 3400N but friction has a force of 400N going against it. What is th
jonny [76]

The acceleration of the car : 2.5 m/s²

<h3>Further explanation</h3>

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

<h3 />

Mass of the car = 1200 kg

Forward force = 3400 N

Friction force = 400 N

The direction of motion of the friction force will be opposite to the forward force, so that both of them can be subtracted to get the value of the net force (net force: combination / sum of all forces acting on an object)

\tt \sum F=3400-400=3000~N

So the acceleration :

\tt a=\dfrac{\sum F}{m}\\\\a=\dfrac{3000}{1200}\\\\a=2.5~m/s^2

In the following reaction, 2NaCl 2Na + Cl2 sodium and chlorine are products, salts, reactants, or ions?
avanturin [10]

The answer is: sodium and chlorine are products.

Balanced chemical reaction of sodium chloride decomposition:

2NaCl → 2Na + Cl₂.

Decomposition is reaction where one substance is broken down into two or more simpler substances.  

From one chemical compound (in this example sodium chloride) two new substances (sodium and chlorine) are produced.
