A question about the amplitude graph of the pendulum:
Should I say; Period does not depend on Amplitude and just make a zero slope graph just like the mass graph.

OR

Should I say; The time period of a pendulum changes as the amplitude changes, but change is negligible if the amplitude is very small. Period only depends on amplitude, if the amplitude isn't very small and make a positive slope graph that represents a slight change as the amplitude of pendulum increases.

Q2: What's the maximum amplitude of a 0.71m pendulum is it 90° or 180°?

Q3: As a negative test charge moves farther from a negative charge in an electric field, the potential energy?

a.decreases.
b. increases.
c. doubles.
d. remains the same.

Q4: If a magnetic field points upward and the current is to your left, the force is.

a. toward you
b. to your right
c. away from you
d. to your left

Q5: A device used to measure both magnitude AND direction of an electric current is a(n)

a. ammeter.
b. galvanometer.
c. voltmeter.
d. ohmmeter.

Q6: The current is least in a rotating loop when the loop’s motion is __________ the magnetic field.

a. slow and perpendicular to
b. slow and parallel to
c. fast and perpendicular to
d. fast and parallel to

Q7: The force on a test charge in an electric field is __________ the magnitude of the field.

a. inversely proportional to
b. directly proportional to
c. inversely proportional to the square of
d. unrelated to

The following table lists the weight of individuals before and after taking a diet prescribed by a weight-loss company for a month:

You may find this Student's t distribution table useful in answering the following questions. You may assume that the differences in weight are normally distributed.

a)Calculate the sample variance (s_d²) of the changes in individual weights. Give your answer to 2 decimal places.

s_d² =

b)A disgruntled customer states:

"This weight-loss company is a complete farce. All the people I know who signed up experienced no changes in their weight at all. I seriously doubt this diet has any effect whatsoever. I want my money back!"

You plan to do a hypothesis test on this claim where the hypotheses are:

H₀: the customer's claim is true and the program has no effect on weight
H_A: the customer's claim is not true and the program does have an effect on weight, whether it increases or decreases

According to the data given, you should accept, reject, not reject the null hypothesis at a confidence level of 90%.

Discussion question #1 – Draw two graphs side-by-side that show the market equilibrium price for soy beans as $3 per pound. The second graph is for Sally the soy bean farmer whose profit maximizing output is 80 pounds of soybeans. Show on your graph Sally making a profit of $140 at the market price of $3. Label all curves you draw and clearly indicate the profit region.
1. Is the above scenario a short-run or long-run equilibrium?
2. If it is not a long-run equilibrium, tell me how you know this?
3. What do you expect to happen in the long-run?
4. What effect will these long run changes have on either the supply or demand curve in the U.S. Soy bean market?
5. What effect will these long run soy bean market changes have on Sally the soy bean farmer?
6. What happens in the long run to soy bean prices?
7. What happens in the long run to the quantity of soy beans produced in the market?
8. What happens in the long run to the quantity of soy beans produced by Sally?

draw 2 graphs below Label the initial equilibrium points “A” in both graphs below…label the new long-run equilibrium points “B” on your graph below.

The following transactions occurred during 2021:

The vendor provides monthly support and upgrades for 4 months following the month of installation (through end of August). The value of the system and cables is $50,000, the value of the installation services is $22,000, and the value of the monthly support totals $6,000.

Grab a blank sheet of paper and try some inflation analysis on your own. Take a picture or scan your sheet, and upload it after you are finished. This contributes to your participation grade in the class.

1. Because inflation increased by only 1.7% in 2008, the American Association of Retired Persons comments that this is “an unfortunate side effect of inflation, since Social Security payments, which are indexed to inflation, will increase by only 1.7% in 2008.” Comment on whether this is an “unfortunate side effect of inflation” or not.
2. The Federal Reserve Bank (Fed) can impact the economy through changes in the Federal funds rate, because changes in this interest rate will change all interest rates throughout the economy. The Federal funds rate was constant at 5.25% from 1996–1998, a time of falling inflation. What impact did this have on real interest rates during this time? What was likely to happen to investment spending?
3. “Traveling in Turkey is much cheaper now than it was 10 years ago,” says a friend. "Ten years ago, a dollar bought 1,000 lira; this year, a dollar buys 1,500 lira.” Total inflation over this period was 25% in the United States and 100% in Turkey. Is your friend right or wrong—has it become more or less expensive to travel in Turkey?
