a circuit contains 2 ohm and 4 ohm resistors connected in parallel, find the total resistance & the amount of current in eac
Lynna [10]

Answer:

Explanation:

Resistance

R = R1 * R2 / (R1 + R2)

R1 = 2

R2 = 4

R = 2*4 / (2 + 4)

R = 8 / 6

R = 1.3333

Current R1

R1 = 2 ohms

V = 12 volts

I = ?

V = I * R

12  = I * 2

12/2 = I

I = 6 amperes.

Current R2

V = 12 volts

R = 4 ohms

I = ?

V = I * R

12 = I * 4

12/4 = I

I = 3 amps

what is the value of the constant for a second order reaction if the reactant concentration drops from .657 M to ,0981 M in 17 s
yaroslaw [1]

Answer : The value of the constant for a second order reaction is, 0.51M^{-1}s^{-1}

Explanation :

The expression used for second order kinetics is:

kt=\frac{1}{[A_t]}-\frac{1}{[A_o]}

where,

k = rate constant = ?

t = time = 17s

[A_t] = final concentration = 0.0981 M

[A_o] = initial concentration = 0.657 M

Now put all the given values in the above expression, we get:

k\times 17s=\frac{1}{0.0981M}-\frac{1}{0.657M}

k=0.51M^{-1}s^{-1}

Therefore, the value of the constant for a second order reaction is, 0.51M^{-1}s^{-1}

12. An organ pipe that is 1.75 m long and open at both ends produces sound of
podryga [215]

Answer:

354 m/s

Explanation:

For the second overtune (Third harmonic) of an open pipe,

λ = 2L/3................................ Equation 1

Where L = Length of the open pipe, λ = Wave length.

Given: L = 1.75 m.

Substitute into equation 1

λ = 2(1.75)/3

λ = 1.17 m.

From the question,

V = λf.......................... Equation 2

V = speed of sound in the room, f = frequency

Given: f = 303 Hz.

Substitute into equation 2

V = 1.17(303)

V = 353.5

V ≈ 354 m/s

Hence the right answer is 354 m/s
