Why do the voltage and current in the pickup coil cycle between negative and positive? Explain in detail using Faraday’s Law. Remember, Lenz’s Law is part of Faraday’s Law! Although it will not be covered explicitly in this class, this is known as alternating current. Points to discuss: How the magnetic flux through the loop changes as the magnet rotates. Is the flux maximal when the magnet is horizontal or vertical on the screen? Why?) How this changing magnetic flux works to create an emf (potential difference) in the coil which alternates over time (use the Faraday’s law equation)

> Gymnosperm seeds are found in fruits, which are mature ovaries. (True/False)

>Small or trailing plants generally have a taproot system that spreads out like a thick mat below the soil surface. (True/False)

> If a flaccid cell (Ψ = −0.7 MPa) is placed in a solution with a lower solute concentration (Ψ = −0.1 MPa), the cell will gain water and become turgid. (True/False)

> The sporophytes of mosses can live independently of the gametophytes. (True/False)

> Changes in turgor pressure of guard cells regulate stomatal opening and closing in leaves of angiosperms. (True/False)

As more potential risky assets become available, explain and show graphically the concept of the efficient frontier. c. Explain and show how risk averse investors will choose utility maximizing portfolios from the efficient frontier.

This week you have learned about the market for loanable funds. In Canada, how has the Coronavirus pandemic affected the market for loanable funds?

• Explain why you think that the pandemic changes one variable in the model.
• Describe the impact on the market equilibrium, including the impact on all other relevant variables.
• Address only *one* shift in the market.
• Think about the variables that will cause a shift (either in demand or supply):
  • Government spending (G)
  • Taxes and/or transfers (T/Tr)
  • Consumption/private saving (C/Sp)
  • Firms’ investment spending (I)

.

1. List the 4 phases of the business cycle.

Which phase are we in right now?

What evidence do you have to support your theory?

Describe who is in the labor force.

Who is not included in the labor force. In the past 20 years or so, the baby boom generation has been retiring. It is estimated that 10,000 turn 65 years old every day in the US. In addition, record numbers of workers gave up looking for jobs in the 2008-09 recession. How do these demographic and cultural changes affect the unemployment rate?

You will perform an experiment using dialysis tubing. Dialysis tubing is an artificial membrane with specific pore sizes. It is used in dialysis, a process which involves the removal of very small molecules from a solution.

1. In what ways is dialysis tubing a semipermeable membrane?
How would you know?

2.

Predict what you believe will be the changes in movement of water through osmosis in the following instances:

A. Dialysis bag containing distilled water submerged in distilled water.

B. Dialysis bag containing 100% sucrose solution submerged in distilled water.
