The same braking force does work on these objects to slow them down. The work done is equal to their change in kinetic energy:
FΔx = 0.5mv²
F = force, Δx = distance traveled, m = mass, v = speed
Isolate Δx:
Δx = 0.5mv²/F
Calculate Δx for each object.
Object 1: m = 4.0kg, v = 2.0m/s
Δx = 0.5(4.0)(2.0)²/F = 8/F
Object 2: m = 1.0kg, v = 4.0m/s
Δx = 0.5(1.0)(4.0)²/F = 8/F
The two objects travel the same distance before stopping.
Answer:
B. A solenoid carries an electric current.
C. An electromagnet is a solenoid with a metal core.
E. A solenoid induces a magnetic field in a metal core.
Explanation:
An electroiman is a large number of wire turns (solenoid) that are wrapped around a magnetic core made of a ferromagnetic or ferrimagnetic material, such as iron. The metal core is composed of "tiny imans", when a current is passed through the solenoid, its magnetic field penetrates the iron, and causes the "tiny imans" to aligning parallel to the magnetic field, creating a large magnetic field.
