I hope this will help you
Explanation:
The air that is inside a ship is much less dense than water. That's what keeps it floating! The average density of the total volume of the ship and everything inside of it (including the air) must be less than the same volume of water.
Please make me brilliant
<span>The formula for the volume of a sphere is: V = (4/3)π r^3
But you only know the diameter that being 24 cm.
The easiest thing to do is to divide by 2 to get the radius. r = 12
Then plug that in: V = (4/3)π 12^3

Answer:
OH⁻ = 1.05×10⁻¹³ M
Explanation:
Given data;
H₃O⁺ = 9.61×10⁻² M
OH⁻ = ?
Solution:
First of all we will calculate the pH.
pH = -log [H⁺]
pH = -log [H₃O⁺]
Because pH is also the hydronium ion concentration.
pH = -log [ 9.61×10⁻²]
pH = 1.02
It is known that,
pH + pOH = 14
1.02 + pOH = 14
pOH = 14 - 1.02
pOH = 12.98
Concentration of OH⁻.
pOH = -log [OH⁻]
12.98 = -log [OH⁻]
OH⁻ = 10∧-12.98
OH⁻ = 1.05×10⁻¹³ M
Hey there!
When plants grow towards the sunlight they get more light.
This is because the sun gives light. It wouldn't be "C" because sunlight makes plants survive, it wouldn't be "A" because sunlight doesn't decrease the size, and it wouldn't be "D" because the sunlight only makes it survive, not actually live longer. This means your answer is option B: they get more light.
Hope this helps
Have a great day (:
Answer:
Coefficients are the numbers in front of the formulas.
