Ch 31 HW Exercise 31.10 7 of 15 Constants You want the current amplitude through a inductor with an inductance of 4.90 mH (part
sergey [27]

Answer:

f = 130 Khz

Explanation:

In a circuit driven by a sinusoidal voltage source, there exists a fixed relationship between the amplitudes of the current and the voltage through any circuit element, at any time.

For an inductor, this relationship can be expressed as follows:

VL = IL * XL (1) , which is a generalized form of Ohm's Law.

XL is called the inductive reactance, and is defined as follows:

XL = ω*L = 2*π*f*L, where f is the frequency of the sinusoidal source (in Hz) and  L is the value of the inductance, in H.

Replacing in (1), by the values given of VL, IL, and L, we can solve for f, as follows:

f = VL / 2*π*IL*L = 12 V / 2*π*(3.00*10⁻³) A* (4.9*10⁻³) H = 130 Khz

An airplane flies 1,592 miles east from Phoenix Arizona, to Atlanta,Georgia,in 3.68 hours. What is the average velocity of the a
Fudgin [204]

Answer:

The average velocity would be 217 m/s.

Explanation:

Average velocity is calculated by v(avg)=final velocity+inital velocity over 2

Displacement is the change in position (vector)

Velocity is calculated by s= d/t distance/time

A student applies a force 6 newtons to move a bool 1.5 meters across a table. How much work, in joules did the student do?​
Anna [14]

Answer:

  1. 9 J

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 6 × 1.5

We have the final answer as

<h3>9 J</h3>

The phase of matter which is exposed to normal atmospheric pressure is solely dependent upon temperature? true or false
Diano4ka-milaya [45]
The statement above is true. The phase of matter which is exposed to normal atmospheric pressure is indeed solely dependent upon temperature. If the matter is exposed to the normal atm pressure, its temperature depends on it.

Consider a pendulum of length 3. 171 m. The acceleration of gravity is 9. 832 m/s2. A) what is its period at the north pole?answ
ch4aika [34]

The period of the pendulum of length 3. 171 m when acceleration of gravity is 9. 832 m/s, is 3.57 seconds.

<h3>What is time period of pendulum?</h3>

Pendulum is the body which is pivoted to a point and perform back and forth motion around that point by swinging due to the influence of gravity.

The time period of a pendulum is the time taken by it to complete one cycle of swing left to right and right to left.

It can be given as,

T=2\pi \sqrt{\dfrac{L}{g}}

Here, (g) is the gravitational force of Earth and (L) is the length of the pendulum.

A pendulum of length 3.171 m. The acceleration of gravity is 9.832 m/s2. The period at the north pole is,

T=2\pi \sqrt{\dfrac{3.171}{9.832}}\\T=3.57\rm\; s

Thus, the period of the pendulum of length 3. 171 m when acceleration of gravity is 9. 832 m/s, is 3.57 seconds.
