Question
Chapter 26, Problem 1RCQ
To determine
The results of changing magnetic fields.
Expert Solution & Answer
Answer to Problem 1RCQ
Solution:
A changing magnetic field induces an electric field.
Explanation of Solution
When magnetic flux linked with a coil is changed an emf is induced. Magnetic flux is the product of magnetic field and the area of coil. So when magnetic field changes, the magnetic flux linked with a coil will change and thus an emf will be induced. That induced emf creates an electric field in the coil.
Conclusion:
Thus a changing magnetic field induces an electric field.

Required information
A bungee jumper leaps from a bridge and undergoes a series of oscillations. Assume g = 9.78 m/s².
If a 60.0-kg jumper uses a bungee cord that has an unstretched length of 30.1 m and she jumps from a height of 45.2 m above a river,
coming to rest just a few centimeters above the water surface on the first downward descent, what is the period of the oscillations?
Assume the bungee cord follows Hooke's law.
Required information
The leg bone (femur) breaks under a compressive force of about 6.50 × 104 N for a human and 12.3 × 104 N for a horse.
The human femur has a compressive strength of 160 MPa, whereas the horse femur has a compressive strength of 140
MPa.
What is the effective cross-sectional area of the femur in a horse? (Note: Since the center of the femur contains bone marrow, which
has essentially no compressive strength, the effective cross-sectional area is about 80% of the total cross-sectional area.)
