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
Answer:
Buoyancy - it is what perceive as the tendency of an object to rise when when it is submerged in a fluid it is can be defined as the ability of an object to float in the fluid .
Thrust - It is a reaction forced described quantitavely by newton third law
Answer:
a) E = 1.47 × 10^5 N/C
b) south
Explanation:
The magnitude of an electric field can be defined mathematically as;
E = F/q ........1
Where,
E = magnitude of the electric field
F = electric force
q = charge on the proton
Given;
F = 2.36 × 10^-14 N
Note that charge on a proton is known as Qp = 1.602 × 10^-19 C
q = 1.602 × 10^-19 C
Substituting into equation 1, we have;
E = 2.36 × 10^-14 N/1.602 × 10^-19 C
E = 1.47 × 10^5 N/C
b) The direction of the electric field;
From equation 1
E = F/q ........1
since both electric field and electric force are vector quantity and q is a positive charge (constant), then both the electric field and electric force would be parallel to each other. Therefore the electric field is directed to the south also.
(When a vector is multiplied by a positive constant the direction remains the same)
Answer:
D) The given reaction is Exothermic, because energy is released
Explanation:
Here, given that Zinc is added to a beaker containing hydrochloric acid.
Also, the beaker gets warm.
⇒The energy is released in the form of heat.
EXOTHERMIC reactions are those type of reactions in which energy is released in the form of heat.
When the beaker gets warm, the reaction is exothermic in nature.
Hence, the given reaction is Exothermic, because energy is released
Answer:Uniform between the plates
Explanation:
Electric Field due to infinite sheet with uniform charge is given by
Where 
=charge density
=Space Permittivity
From the formula we can see that Electric field is independent of distance of the particle, so it is uniform between the plates .
