The answer is 12g of Carbon
The difference between speed and velocity is that speed is the time rate at which an object is moving along a path. While velocity is the rate and direction of the object’s movement.
if something is travelling at a constant velocity are the forces balanced or unbalanced?
Unbalanced
if something changes motion, are forces balanced or unbalanced?
Unbalanced. If the forces on the object is equal and in opposite directions, then the forces are balanced, then there would be no change in motion
what are the three ways to accelerate?
1. A change in velocity
2. A change in direction
3. A change in both velocity and direction
The fluid filled area between the pleural layers is called the pleural cavity.
b. Polar covalent bonds. The polar N-H bonds hold the NH3 molecules together. They are <em>intramolecular forces</em> of attraction <em>within a molecule</em>.
All the other options are <em>wrong</em>. They are <em>intermolecular forces</em> — the attractive forces <em>between different molecules</em>.
The answer should be; 11
The atomic mass number is found by combining the number of protons and neutrons
Hope this helps :)
