I think its a im not sure
Answer:
Frictional force increases with the increase in the roughness of the surface.
Explanation:
You will see that the rougher the surface, the greater the wear and tear.
Answer:
Correct answer is A.
The higher the enzyme, the higher the Vmax
Explanation:
Although, in the absence of enzyme, the rate of a reaction(Vmax) increase linearly with substrate concentration. The reaction rate is given as dp/dt.
The rate of a reaction involving enzyme also increases.
At low enzyme concentrations or high substrate concentrations, all of the available enzyme active sites could be occupied with substrates. Therefore, increasing the substrate concentration further will not change the rate of diffusion. In other words, there is some maximum reaction rate (Vmax) when all enzyme active sites are occupied. The reaction rate will increase with increasing substrate concentration, but must asymptotically approach the saturation rate, Vmax. Vmax is directly proportional to the total enzyme concentration, E
The dots in the Lewis dot structure symbolize an atom's elements.
<span>Since Na^+ is a positive ion (cation) with a charge of +1, it indicates that it has lost an electron. </span>
<span>Since Na had one electron, to begin with, and it is now lost, Na^+ will have no dots. However, the charge must still be written as a superscript. </span>
<span>Therefore, the Lewis dot structure for Na^+ is just Na^[+] </span>
P = density × gravity acceleration × height
P = 1200 × 9.81 × 15/100
P = 1765.8
