Answer:
Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration. So the pH is the -log of the [hydronium ion].

The expression for the block's centripetal acceleration is derived as ω²r or v²/r.
<h3>
What is centripetal acceleration?</h3>
The centripetal acceleration of an object is the inward or radial acceleration of an object moving in a circular path.
The expression for the block's centripetal acceleration is derived as follows;
ω = dθ/dt
where;
- ω is the angular speed
- θ is the angular displacement
- t is the time of motion
ac = ω²r
where;
- r is the radius of the circular path
Also, ω = v/r
ac = (v/r)²r
ac = v²/r
Thus, the expression for the block's centripetal acceleration is derived as ω²r or v²/r.

Answer:
From what I know they postponed the movies that were suppose to come out.
Answer: a all the outer planets are large
Explanation: because i have the smarts
Answer:
Neither aspects of Dominique are correct.
Explanation:
They will not have the same speed before hitting the ground.
The block C has an initial horizontal velocity v₀ₓ , therefore the total ultimate speed before hitting the ground is v = √ v₀ₓ² + vy²
It didn't matter how the blocks were dropped, they all landed at the same time. If any block has an initial vertical velocity it will have a higher end velocity. If Dominique means dropped from the rest then the previous claim is true. It is important how they were dropped.
The Dominique must said : The vertical speed will be the same because of conservation of energy.
The fact is, they all landed at the same time and that is true. And it is important how they are thrown away.
God is with you!!!
