Question 8 The nylon rope from which a mountain climber is suspended has a force constant of 1.40 x 104 N/m. How much would this rope stretch to break the climber's fall if he free-falls 2.16 m before the rope runs out of slack, given his mass plus and the mass of his equipment are 91.6 kg? Hint: Use conservation of energy. You can assume the amount the rope stretches is small compared to the distance of his fall. Select...

In the Consortium Library here on campus, you may have seen the Foucault pendulum, which is used to demonstrate the rotation of the earth. In one such pendulum, a 100 kg bob swings from a 20.0-m-long cable with a maximum angular displacement of 5.0°. a. What is the period of this simple pendulum? b. If the “simple pendulum” described above was replaced by a solid rod of the same length and mass, what would be the period of the new...

Question 9:
Part A:
Part B:
An electronic defibrillator used on heart attack victims works by delivering charge stored in a capacitor. If the device utilizes a 13.0 μF capacitor charged to 7.81 × 103 V, what is the energy stored in the capacitor? A parallel-plate capacitor is connected to a battery. What happens to the stored energy if the plate separation is halved while the capacitor remains connected to the battery? Select the correct answer CHECK ANSWER 2 of...

Choose all correct statements about a
pendulum
Select one or more:
a. The period T is almost the same for small initial
displacement angles. There is some change at large angles.
b. If the weight is increased, the time T for one complete
oscillation increases. T, also called the period, is measured in
the upper left.
c. If the length of the pendulum is increased, the time T for
one back and forth ocillation is increased.
