turning off the electric current turns off the electromagnet
Explanation:
Answer:
v = 2.33 103 m / s
Explanation:
The magnetic force is
F = q v x B = i L X B
Where L is wire length and B the magnetic field
Let's calculate the value of the force
F = i L B
Now we can calculate the acceleration using Newton's second law
F = m a
a = F / m
Density is
ρ = m / V
V = π r² L
ρ = m / π r² L
m = ρ π r² L
a = I L B / (ρ π r² L)
a = 10 10³ 2.0 / (8960 π (5.1 10⁻⁴)²)
a = 2.73 10⁶ m/s²
Having the acceleration we use the kinematic equation
v² = v₀² + 2 a x
v = √ 2 ax
v = √ (2 2,723 10⁶ 1.0)
v = 2.33 103 m / s
Answer:
Tendons connect muscle to bone. These tough, yet flexible, bands of fibrous tissue attach the skeletal muscles to the bones they move. Essentially, tendons enable you to move; think of them as intermediaries between muscles and bones.
Hope this helps! (:
