Answer:
3. all of the above
4. d=m/v
5. gas has well separated particles with no particular arrangement
liquid has particles close together but still with no particular arrangement
and solid has particles that are tightly packed, usually in a regular pattern
6. (idk what number it is but)
the density of the rock is 2.4 g/ml
d=m/v so d=12/v according to the question the mass is 12
to find volume subtract 20-15 because before the rock was 15 and after the rock was 20, so then you get 5 for volume
d=12/5 and when you calculate that, you would get 2.4g/ml ; hope this helped :-)
Answer:
0.46786 W
Explanation:
The solution is in the attached file below
Spring tides occur twice each lunar month all year long (they don't depend on any particular season. When there is a new or full moon the average tidal ranges are larger.
These are the characteristics that apply:
- In a solution taste sour: which is consequence of the H+ concentration.
- Corrode metals: the H+ ion reacts with the metal producing a salt and water
-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme:
HA + H2O --> A(-) + H3O(+)
The speed of the man and the chair after the book is thrown is 0.2 m/s.
The given parameters:
- <em>mass of the book, m₁ = 2.1 kg</em>
- <em>speed of the book, u₁ = 7.2 m/s</em>
- <em>mass of the man, M = 70 kg</em>
- <em>mass of the book, m = 9.2 kg</em>
<em />
The total mass of the man and the book is calculated as follows;
m₂ = 70 kg + 9.2 kg
m₂ = 79.2 kg
The speed of the man and the chair after the book is thrown is determined by applying the principle of conservation of linear momentum;
Thus, the speed of the man and the chair after the book is thrown is 0.2 m/s.
