Answer:
An acid
Explanation:
According to the Arrhenius theory of acids and bases "an Arrhenius acid is a compound that increases the concentration of H+ ions that are present when added to water"
Answer:
KE = PE at half the table Height:
Explanation
AT ANY POINT IN THE BOOK'S FALL,
TOTAL E = PE +KE
THE TOTAL E IS CONSTANT
Before the book is pushed off, the total energy is potential
TOT E=PE =MGH
BEFORE THE BOOK HITS THE GROUND, THE TOTAL E IS KINETIC
TOT=KE = MVXV/2
WHEN KE = PE
KE+PE =<u> MGH (STARTING ENERGY SINCE E IS CONSERVED)</u>
<u>OR PE+ PE = MGH</u>
<u>OR MGH' + MGH' =MGH</u>
<u>OR 2H' =</u>H
H' (NEW HEIGHT) =H/2
The acceleration of Moby is 2 m/s²
<u>Explanation:</u>
Given:
Time, t = 5 seconds
Velocity, v = 10 m/s
Acceleration ,a = ?
We know:

On substituting the value we get:

Therefore, the acceleration of Moby is 2 m/s²
Answer:
The cube will contain 8000 mL of the fluid.
Explanation:
- Knowing that the volume of the cube = L³.
where, L is the edge length.
∴ V of the cube = L³ = (20.0 cm)³ = 8000 cm³.
Knowing that 1.0 cm³ = 1.0 mL.
<em>∴ The cube will contain 8000 mL of the fluid.</em>
Controlled because there is always going to be a control group and an experimental group so that you could see the difference in the results
