a)   increasing

b) decreasing

c) not changing

Q5. State, giving reasons, whether the answers given to Q.4. are to be expected on the basis of those given in Q.1.

Q6. What is the effect of the presence of the rod on the current induced in the larger
solenoid?

Q7. How does the induced current depend on the rate at which the current in the smaller
solenoid is altered?

Q8. What does the graph indicate?

Part 3

Q9. Are your results consistent with Lenz' s Law?

Comet Bennett (1969 Y1) came to perihelion (closest approach to the Sun) on April 4, 1970. The

period of this comet is 1678 years and its orbital eccentricity is 0.9962. Calculate, in AU, the semi-major

axis, perihelion distance, and aphelion distance (farthest recession from the Sun) of the orbit of this

comet.

Part II

ANALYSIS QUESTIONS

1.   Plot a graph of magnetic field B vs. the current I through the solenoid. You may launch a fresh copy of LoggerPro, or use the file "magnetic field graph' in the Lab 08 folder.

2. Determine the equation of the best-fit line, including they-intercept. Note the constants and their units.

3. For each of the measurements of Part II, calculate the number of turns per meter. Enter these values in the data table.

4. Plot a graph of magnetic field B vs. the turns per meter of the solenoid (n). Use either Graphical Analysis or graph paper.

5. How is magnetic field related to the turns/meter of the solenoid?

6. Determine the equation of the best-fit line to your graph. Note the constants and their units

7.   From Ampere's law, it can be shown that the magnetic field B inside a long solenoid is B = µ0nl where I-to is the permeability constant. Do your results agree with this equation? Explain.

8.   The permeability constant for a vacuum, I-to, has a value of 4rcx10-7 Tm/A. Assuming the equation in step 8 applies to the Slinky, obtain a value of re from your graphs, and compare with the 'theoretical' value.

9.   Was your Slinky positioned along an east-west, north-south, or on some other axis? Will this have any effect on your readings?

what is the ratio of the sun"s gravitational farce on you to the earth's gravitational force on you?  assume you have a mass of 80 kg .

Suppose that a passenger intent on lunch during his first ride in a hot-air balloon accidently drops an apple over the side during the balloon

An observer on Earth receives a signal of 6.614 THz. Thirty minutes later, he receives another signal, followed by a third signal 24.331 minutes later after the second. The observer on Earth knows that the ship should be sending signals at a 2.500THz. How far away is the ship from Earth and how often is the captain of the ship sending signals according to her watch? (Hint: look up the formula for the Relativistic Doppler Shift.)

PLEASE SHOW ALL WORK!!

Did anyone ever heard about this?I've never seen any serious physicist talk about "mass fluctuations".

Here is the man in his own words: http://www.intalek.com/Index/Projects/Research/woodward1.pdf

And what about this guy: http://aetherwavetheory.blogspot.com/

He claims his theory can explain virtually every unsolved problem in contemporary physics.

1. A damped driven harmonic oscillator with m=12 kg, k=280 N/m, and b=75 kg/sis subjected to a driving force given by F(t) = F₀cos(ωt), where F₀=55 N.

a) What value of ω results in steady-state oscillations with maximum amplitude?

b) What is the maximum amplitude?

c) What is the phase angle?

2. An undamped, driven harmonic oscillator satisfies the equation of motion

where the driving force is switched on at t=0.

a) Assuming a solution of the form x(t) = A(ω)sin(ωt-δ), find expressions for the amplitude A(ω) and the phase angle δ.

A ballistic pendulum consists of a thin rod AB (length = 2.0 m; mass = 1.14 kg) that is rigidly attached to a solid sphere that has a center C, radius = 0.4 m, and mass = 2.45 kg. A bullet (mass = 0.01 kg) is fired at point C with a speed of 675 m/s.
Determine the amount of kinetic energy lost by the system due to the impact.

You will estimate how much slower an ice skater would spin, if a can of soda dropped into her hand while she was spinning. You may model her body as a vertical cylinder of radius 20 cn abd nass 50 kg, spinning about a vertical axis. Assume that shes initially spinning 10 times per second, so that initially wi=20pis-1. Suddenly she is handed the soda can, which is small enough that we can model it as a point-like mass of .33kg, which she holds at a distance 60cm from the axis of rotation. (a) find nthe moment of inertia of the ice skater before the soda can drops in her hand. (b) find the moment of inertia of the point-like soda can relative to the axis about which the ice skater rotates. (c) find the total moment of inertia of the system consisting of the ice skater and the soda can. (d) find her angular velocity wf, after the soda can falls into her hand and (e) calculate the percentage difference, compared to her initial angular velocity wi.

A person with a mass of 90 kg performs a vertical jump on a force plate. During the initial phase of the countermovement, vertical force is 540 N for 0.234 s. Then the force is increased to 1553 N and stays at that value until the jumper leaves the ground. At what point in time (s), referenced from the initial point of the countermovement, does the person reach the bottom of the movement? Prior to initiation of the countermovement, the velocity of the center of mass was zero.

Is F = μsN an exact equation or an empirical/approximate model? Is it possible to take into account the fundamental interactions? Include reasons for your answer.

A cameraman on a pickup truck is traveling westward at 16 km/h while he videotapes a cheetah that is moving westward 31 km/h faster than the truck. Suddenly, the cheetah stops, turns, and then run at 50 km/h eastward, as measured by a suddenly nervous crew member who stands alongside the cheetah's path. The change in the animal's velocity takes 1.7 s. What are the (a) magnitude and (b) direction of the animal
