Let's examine the given choices:
V = (4/3)*pi*(r)^3 is the rule to calculate the volume of the sphere
V = (1/3)*pi*(r)^2*h is the rule to calculate the volume of the cone
V = s^3 is the rule to calculate volume of the cube
V = pi*(r)^2*h is the rule to calculate volume of the cylinder
Now, the ball can be treated as a perfect sphere, therefore, to calculate its volume we will use the rule of the volume of sphere.
Based on this, the correct choice is:
V = (4/3)*pi*(r)^3
Answer:
d = 3 g/cm³
Explanation:
Given data:
Mass of stone = 27 g
Volume of water = 10 cm³
Volume of water+ stone = 19 cm³
Volume of stone = ?
Density of stone = ?
Solution:
Volume of stone = total volume - volume of water
Volume of stone = 19 cm³ - 10 cm³
Volume of stone = 9 cm³
Density of stone:
d = m/v
d = 27 g/ 9 cm³
d = 3 g/cm³
Answer:
Transitional metals are good conductors of both heat and electricity.
But since there aren't any. It could be Calcium.
<u>Explanation:</u>
We are given a mixture of hydrochloric acid (HCl) and acetic acid . The given mixture is a mixture of strong acid and a weak acid.
Strong acid is defined as the acid that can be get completely ionized or dissociated in an aqueous solution. Weak acid is defined as the acid which does not dissociate completely in an aqueous solution.
When a mixture of HCl and is titrated against NaOH (strong base), strong acid will get neutralized first because it is completely dissociated in the solution and can be easily neutralized.
