Answer:
The displacement is zero miles
Explanation:
The displacement of an object that moves from point A to point B is defined as

Where d is the displacement of the object. The displacement does not depend on the trajectory of the object. It only depends on the linear distance between the end point and the starting point.
In this case we know that the person walks from home to work and then walks from work to home. Therefore, the total displacement is the linear distance between the point where its journey begins and the point where the route ends.
The tour begins on the front porch of your house and ends on the front porch of your house (when you return from work). If we call A to the front porch of the house then the displacement is:

The displacement is zero miles, since the person finishes the journey just where it started (front porch)
Answer:
Explanation:
Given that,
Frequency f = 5 kHz = 5000Hz
Voltage V=45V
Current In inductor I = 65mA
I = 65 × 10^-3 = 0.065A
We want to find inductance L
We know that the reactive inductance cam be given as
XL = 2πFL
Where
XL is reactive inductance
F is frequency
L is inductance
Then,
L = XL/2πF
From ohms law
V = IR
We can calculate the receive reactance of the inductor
V = I•XL
Then, XL = V/I
XL = 45/0.065
XL = 692.31 ohms
Then,
L = XL/2πF
L = 692.31/(2π×5000)
L = 0.02204 H
Then, L = 22.04 mH
The inductance of the inductor is 22.04mH
Answer: 294 N
Explanation:
Since the Normal Force
is equal to the weight
of the dog, we have:

Where:
is the mass of the dog
is the acceleration due to gravity on the Earth's surface
Solving:


Answer:
-65.6 m is the answer.
Explanation:
Brainly deleted my answer even though you got it correct, so this is just a repost.
Answer: positive
Explanation: because opposites attract and north=positive and south=negative the answer should be positive.
