Answer:
The answer is North
Explanation:
The direction of the field is taken to be the direction of the force it would exert on a positive test charge.
The density is calculated as mass per volume, so if we want to solve for mass, we would multiply density by volume.
For Part A: if we have a density of 0.69 g/mL, and a volume of 280 mL, multiplying these will give a mass of: (0.69 g/mL)(280 mL) = 193.2 g. Rounded to 2 significant figures, this is 190 g gasoline.
For Part B: if we have a density of 0.79 g/mL, and a volume of 190 mL, multiplying these will give a mass of: (0.79 g/mL)(190 mL) = 150.1 g. Rounded to 2 significant figures, this is equal to 150 g ethanol.
Answer:
yes answer os Na because it's electronic configuration is 1s^2,2s^2,2p^6,3s^1
1. She would want a balanced force so she doesn't fall but, well, keep her balance.
2. Frictional force because when an object slows down it's because a higher amount of friction is acting on it.
3. It would be magnitude and direction because is like the size of the object and they need to know how much force it will take to move it.
4. Is the same as 3...
5. A push and a pull are a force.
I hope this helps!
