a).
-- There were 10.00 mL of water in the graduated cylinder originally.
-- After the marble was added to the cylinder and sank, the total volume
of water and marble in the cylinder was 11.20 mL.
-- The extra 1.20 mL that suddenly showed up was the volume of the marble.
-- We can use 1 mL = 1 cm³ .
-- The volume of the marble was <em>1.20 cm³ </em>.
b).
Density = (mass) / (volume)
For the marble . . .
Density = (3.05 g) / (1.20 cm³) = <em>2.54 gm/cm³</em> (rounded)
They are similar because of their colour theyre differnt because there aint any silver
Answer:
The correct answer is: 0°C + 0°C = 32°F
Explanation:
We need to remember the conversion equation from Celsius to Fahrenheit:

In our case x = 0, then y will be:


Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.
Then, knowing that 0°C = 32°F we can conclude that:
