Answer the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets

Answer:
v = 1.25 m/s
Explanation:
We have,
Distance covered by a person is 10 meters
Time taken by him to cover that distance is 8 seconds.
If we want to find the speed of a person, we must know distance covered by it and taken. In this case, we know both distance and time. His speed is given by :
So, the speed of the person is 1.25 m/s.
Answer:
a) 6m/s, 0m/s, -6m/s
b) 16m, 25m, 16m
Explanation:
For the first part of the problem, use the Kinematic Equation for Final Velocity:
<h2>V = Vi + at</h2>
You are looking for the final velocities of the times: 2s, 5s, and 8s (plug those in for t). We also know that the acceleration is going down so it is negative (-2 is plugged in for a). 10 is the initial velocity and it is positive.
For the second part of the problem, use the Kinematic Equation for Displacement:
<h2>ΔX = Vi(t) + 1/2a(t²)</h2>
You are looking for the displacement of the piano at times: 2s, 5s, and 8s (plug in and square at t). Again, the acceleration is negative because it is in the direction of down, so plug -2 in for a. The initial velocity is positive 10. Plugging those numbers in for each variable should get the correct answer.
Hopefully this helped, I went on here in search of an answer and found it out myself and since no one has answered it yet, I'll help someone else out.
