When 1 carbon atom combines with 2 oxygen atoms, the resulting substance is carbon dioxide which is a Compound. Hope this helps.

Here is the answer that completes the statement above. We can study how galaxies evolve because THE FARTHER AWAY WE LOOK, THE FURTHER BACK IN TIME WE SEE. This means that the more we discover more about what's happening in the universe, the more we become curious to know how and when it began. Hope this helps.

Explanation:</h3>
<u>Step 1: Define</u>
Mass <em>m</em> = 1.50 × 10³ kg
Velocity <em>v</em> = 20 m/s east
Change in time Δt = 5.00 s
<u>Step 2: Find Magnitude</u>
- Substitute [Momentum]: P = (1.50 × 10³ kg)(20 m/s)
- Multiply: P = 30000 kg · m/s
<u>Step 3: Find Force</u>
<em>We use the Law of Conservation of Momentum to find our break force acting upon the car.</em>
- Substitute [Impulse]: 30000 kg · m/s = F(5.00 s)
- Rewrite: 30000 N · s = F(5.00 s)
- Divide 5 on both sides: 6000 N = F
- Rewrite: F = 6000 N
Since the car is deaccelerating, the break force would be towards the west direction (negative as east is our positive direction).
∴ F = -6000 N
Answer: 5 m
Explanation:
We have the following data:
is the intensity of the sound at 7.5 m from the source
is the distance at which the intensity 
was measured
is the intensity of the sound at 
from the source
We have to find
Since the object is radiating the signal uniformly in all directions, we can use the <u>Inverse Square Law for Intensity:</u>
Isolating :
This is the distance at which the intensity is the "threshold of pain"
Now, we have to substract this value to 
to find how much closer to the source can we move:
-- Since the sphere is a conductor, the charge on it will move around
until it's evenly distributed on the surface of the sphere. When every
tiny smitch of charge is the same distance from the charge around it,
they won't need to move around any more.
-- At that point, the situation at the center of the sphere will be:
For every smitch of charge on the surface, causing en electric field
at the center, there is another smitch, of the same size and in exactly
the opposite direction, canceling out the field of the first one.
Every smitch of charge on the surface causes a tiny bit of electric field
at the center, and they all cancel each other.
It turn out that if the sphere is hollow, then the electric field at EVERY
point inside it is zero, not only at the center.
It's exactly the same idea as a sphere with uniform, homogeneous mass.
For that sphere, the gravity at the center is zero.
