Answer:

a) 210 Ω

b) 21 V

c) 0.07 A, 0.03 V

d) VAE = 7 V

VEB = 14 V

VAF = 9 V

VFB = 12 V

Explanation:

a) 100 Ω and 200 Ω are in series, equivalent = 100 + 200 = 300 Ω,

300 Ω and 400 Ω are in series, equivalent = 300 + 400 = 700 Ω

300 Ω and 700Ω are in parallel, so the equivalent resistance between A and B is R where

1/300 + 1/700 = 1/R, get R = 210 Ω

b) Given I = 0.1 A

so VAB = I * R = 1 * 210 = 21.0 V

c) I₁ + I₂ = I = 0.1, so I₂ = 0.1 - I₁

I₁ * 300 = I₂ * 700

I₁ * 300 = (0.1 - I₁) * 700

get I₁ = 0.07 A, I₂ = 0.1 - I₁ = 0.03 A

d) VAE = I₁ * 100 = 7 V

VEB = I₁ * 200 = 14 V

VAF = I₂ * 300 = 9 V

VFB = I₂ * 400 = 12 V

Given that the concentration of bovine carbonic anhydrase is 3.3 pmol ⋅ L − 1 and R max ( V max ) = 222 μmol ⋅ L − 1 ⋅ s − 1 , d
LuckyWell [14K]

Answer:

The turnover number of the enzyme molecule bovine carbonic anhydrase = 67,272,727.27 s^–1.

Explanation:

Given:

The concentration of bovine carbonic anhydrase = total enzyme concentration = Et = 3.3 pmol⋅L^–1 = 3.3 × 10^–12 mol.L^–1

The maximum rate of reaction = Rmax (Vmax) = 222 μmol⋅L^–1⋅s^–1 = 222 × 10^–6 mol.L^–1⋅s^–1

The formula for the turnover number of an enzyme (kcat, or catalytic rate constant) = Rmax ÷ Et = 222 × 10^–6 mol.L^–1⋅s^–1 ÷ 3.3 × 10^–12 mol.L^–1 = 67,272,727.27 s^–1

Therefore, the turnover number of the enzyme molecule bovine carbonic anhydrase = 67,272,727.27 s^–1

Faraday's law states that voltage can be changed by moving the coil out of the magnetic field true or false
NNADVOKAT [17]

As per Faraday's law of induction we know that induced EMF in a conducting closed loop is equal to rate of change in flux in that loop

So here we have

V = \frac{d\phi}{dt}

now when we move out a coil from magnetic field then in this case there will be EMF induced in that coil as here magnetic flux is changing with time linked with the coil.

Now this induced voltage will remain constant if coil is moved out uniformly

But it will not remain constant if coil is moved out with non uniform speed

So this statement is not always true

so answer must be

<u>FALSE</u>
