Answer: option D. Their speed in a vacuum
Explanation:
Electromagnetic waves all have same speed in vacuum. This speed has been calculated to be 3x10^8m/s.
Answer:
Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.
Explanation:
Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.
The volume (in mL) of the 1.00 M LiOH needed to prepare 500.00 mL of 0.075 M of LiOH is 37.5 mL
<h3>How do I determine the volume (in mL) of LiOH needed?</h3>
Dilution formula is given as follow:
M₁V₁ = M₂V₂
Where
- M₁ is the molarity of stock solution
- V₁ is the volume of stock solution
- M₂ is the molarity of diluted solution
- V₂ is the volume of diluted solution
Applying the above formula, we obtain the volume (in mL) of LiOH needed to prepare 500.00 mL of 0.075 M of LiOH. This is illustrated below:
- Molarity of stock solution of LiOH (M₁) = 1.00 M
- Volume of diluted solution of LiOH (V₂) = 500.00 mL
- Molarity of diluted solution of LiOH (M₂) = 0.075 M
- Volume of stock solution of LiOH needed (V₁) =?
M₁V₁ = M₂V₂
1 × V₁ = 0.075 × 500
V₁ = 37.5 mL
Thus, the volume (in mL) of LiOH needed is 37.5 mL
