It’s a centrifuger there are many steps to this do I advise looking on the internet or i could explain if needed
It’s “a”, frequency because the sound waves will cause vibrations in object close by
Answer:
A) 0.50 M
Explanation:
The computation of the number of molarity of the NaOH is given below:
As we know that
Molarity = Moles ÷ liters
where
Moles is 20
And, the liters is 40
So, the molarity is
= 20 ÷ 40
= 0.50 M
hence, the molarity of the NaOH solution is 0.50 M
Therefore the A option is correct
Answer:
<em>An electrical circuit is an unbroken path along which an electrical current occurs and/or will pass. The basic electrical circuit consists of a power supply, two conductive wires (one end of each being connected to each cell terminal) and a small light to which the free ends of the wires leading out of the cell are attached. If the links are made right, the circuit will "close"</em>
