Answer:
Turnover number = 113182s⁻¹
Explanation:
Turnover number is a concept used to know the activity of an enzyme. The higher turnover number, the higher activity of the enzime.
Turnover number is defined as:
Turnover number = Rmax / [E]t
As Rmax is 249 μmol⋅L⁻¹⋅s⁻¹ and [E]t is 2.20 nmol⋅L⁻¹
As 1μmol = 1000nmol, Rmax = 249000 nmol⋅L⁻¹⋅s⁻¹. Replacing:
Turnover number = 249000 nmol⋅L⁻¹⋅s⁻¹ / 2.20 nmol⋅L⁻¹
<h3>Turnover number = 113182s⁻¹</h3>
Explanation:
The particles are further apart in liquids than in solids so when the lemonade changes from a liquid to a solid, the particles would become closer.
The the strength of an electromagnet varies with the quantity and direction of current as well as the number of turns in the coil.
<h3>What as is an electromagnet?</h3>
An electromagnet is a material which operates by the principle of electromagnetism.
Electromagnets possesses both electrical and magnetic properties.
The strength of an electromagnet is affected by the current, the number of turns as well as the material of the electromagnet.
The strength of the given electromagnet will be affected thus:
- increases when using a battery with a higher voltage
- decreases when wrapping the wire around the nail only three times
- is unchanged when changing the direction of the current by reversing the battery connections
- decreases when using a plastic stick in place of the iron nail
- is greatest when holding the nail vertically rather than horizontally.
Therefore, the strength of an electromagnet is affected by current and number of turns in the coil.
