The total distance you haved walked should be 2.6 miles
It’s C
Cause Impulse is found by multiplying the force and change in time (which is simply time)
So if you rearrange the equation for time you end up dividing Impulse by force.
<h3>1)</h3>
No,kinetic energy cannot be negative since its given by KE=mv²,mass cannot be negative and the square of speed cannot b negative.
<h3>2)</h3>
Yes,any force opposing motion or displacement does negative work. They are often referred to as resistive forces (friction,air resistance,drag...)
<h3>3)</h3>
Nope it does not, it just forces the object to move in a circular path known as a centripetal force. It can accelerate an object by changing it's direction but not it's speed.
<h3>4)</h3>
No it cannot,If an object is sliding on the table (assuming it is not an incline), then most probably that normal force cancels out the weights effect or assuming there is an incline, it cancels the weight's y component.
<h3>5)</h3>

The work done is zero
<h3>6)</h3>

The work is just the product of the magnitude of the force exerted and the displacement of the object.
<h3>7)</h3>

<h3>Work is decreasing but positive</h3>
<h3>8)</h3>

<h3>Work is zero</h3>
<h3>9)</h3>

<h3>Work is negative</h3>
Answer:
The inductance remains constant
Explanation:
The inductance value remains constant because it is a intrinsic property of an inductor. Its value depends on physical characteristics and dimensions like length, number of turns, etc.
What changes is the impedance of the inductance. Now, the impedance does changes with the frequency of the AC signal. The relations is as follows:
Z = jωL, where Z is the impedance, j is the imaginary unit, ω is the angular frequency, and L is the inductance.
In terms of frequency ω=2π·f, where f is the frequency of the signal.
So, the impedance in terms of f is:
Z = j·2·π·f·L
If f decreases, the value of the Z decreases too, because if f has a lower value and the other terms remain constant, the value of Z will be lower.
So, the inductance remains constant.
