Answers

Answer 1

In the case of a time-varying force (ie. not constant), is the change in momentum over the time interval. The correct option is D.

The assertion that "A is the area under the force vs. time curve" is false. The impulse, not the work, is represented by the area under the force vs. time curve.

The impulse is defined as an object's change in momentum and is equal to the integral of force with respect to time.

The statement "B is the average force during the time interval" is false. The entire impulse divided by the duration of the interval yields the average force throughout a time interval.

The assertion "C cannot be found" is false. Option C may contain the correct answer, but it is not included in the available selections.

Thus, the correct option is D.

An RLC series circuit has a 1.00 kΩ resistor, a 130 mH inductor, and a 25.0 nF capacitor.(a)The circuit's impedance at 490 Hz is approximately 1013.53 Ω.(b)The circuit's impedance at 7.50 kHz is approximately 6137.02 Ω.

(a) To find the circuit's impedance at 490 Hz, we can use the formula:

Z = √(R^2 + (XL - XC)^2)

where Z is the impedance, R is the resistance, XL is the inductive reactance, and XC is the capacitive reactance.

Given:

R = 1.00 kΩ = 1000 Ω

L = 130 mH = 0.130 H

C = 25.0 nF = 25.0 × 10^(-9) F

f = 490 Hz

First, we need to calculate the inductive reactance (XL) and capacitive reactance (XC):

XL = 2πfL

= 2π × 490 × 0.130

≈ 402.12 Ω

XC = 1 / (2πfC)

= 1 / (2π × 490 × 25.0 × 10^(-9))

≈ 129.01 Ω

Now we can calculate the impedance:

Z = √(R^2 + (XL - XC)^2)

= √((1000)^2 + (402.12 - 129.01)^2)

≈ √(1000000 + 27325.92)

≈ √1027325.92

≈ 1013.53 Ω

Therefore, the circuit's impedance at 490 Hz is approximately 1013.53 Ω.

(b) To find the circuit's impedance at 7.50 kHz, we can use the same formula as before:

Z = √(R^2 + (XL - XC)^2)

Given:

f = 7.50 kHz = 7500 Hz

First, we need to calculate the inductive reactance (XL) and capacitive reactance (XC) at this frequency:

XL = 2πfL

= 2π × 7500 × 0.130

≈ 6069.08 Ω

XC = 1 / (2πfC)

= 1 / (2π × 7500 × 25.0 × 10^(-9))

≈ 212.13 Ω

Now we can calculate the impedance:

Z = √(R^2 + (XL - XC)^2)

= √((1000)^2 + (6069.08 - 212.13)^2)

≈ √(1000000 + 36622867.96)

≈ √37622867.96

≈ 6137.02 Ω

Therefore, the circuit's impedance at 7.50 kHz is approximately 6137.02 Ω.

Suppose that you built the circuit given in Figure 3-2 of your lab instructions with slide wire of total length 7.7cm and try to experimentally determine the value of the unknown resistance Rx where Rc is 7.3.

In the circuit given in Figure 3-2 of your lab instructions with slide wire of total length 7.7cm, we need to experimentally determine the value of the unknown resistance Rx where Rc is 7.3.

If the point of balance of the Wheatstone bridge we built is reached when l2 is 1.8 cm, we have to calculate the experimental value for Rx.

The Wheatstone bridge circuit shown in Figure 3-2 is balanced when the potential difference across point B and D is zero.

This happens when R1/R2 = Rx/R3. Thus, the resistance Rx can be determined as:

Rx = (R1/R2) * R3, where R1, R2, and R3 are the resistances of the resistor in the circuit.

To find R2, we use the slide wire of total length 7.7 cm. We can say that the resistance of the slide wire is proportional to its length.

Thus, the resistance of wire of length l1 would be (R1 / 7.7) l1, and the resistance of wire of length l2 would be (R2 / 7.7) l2.

Using these formulas, the value of R2 can be calculated:

R1 / R2 = (l1 - l2) / l2 => R2

= R1 * l2 / (l1 - l2)

= 3.3 * 1.8 / (7.7 - 1.8)

= 0.905 Ω.

Now that we know the value of R2, we can calculate the value of Rx:Rx = (R1 / R2) * R3 = (3.3 / 0.905) * 7.3 = 26.68 Ω

Therefore, the experimental value for Rx is 26.7 Ω.
