The mass was released from restat from the position 0.0460 m (a) Determine the location of the mass att - 5.515 m (b) Determine if the mass is moving in the positive or negative x direction at t-5515. O positive x direction O negative x direction

Answers

Answer 1

a) The location of the mass at -5.515 m is not provided.

(b) The direction of motion at t = -5.515 s cannot be determined without additional information.

a)The location of the mass at -5.515 m is not provided in the given information. Therefore, it is not possible to determine the position of the mass at that specific point.

(b) To determine the direction of motion at t = -5.515 s, we need additional information. The given data only includes the period of oscillation and the initial position of the mass. However, information about the velocity or the phase of the oscillation is required to determine the direction of motion at a specific time.

In an oscillatory motion, the mass attached to a spring moves back and forth around its equilibrium position. The direction of motion depends on the phase of the oscillation at a particular time. Without knowing the phase or velocity of the mass at t = -5.515 s, we cannot determine whether it is moving in the positive or negative x direction.

To accurately determine the direction of motion at a specific time, additional information such as the amplitude, phase, or initial velocity would be needed.

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.
