A 3.10-N metal bar, 2.00 m long and having a resistance of 10.0 Ω, rests horizontally on conducting wires connecting it to the circuit shown in the figure (Figure 1) . The bar is in a uniform, horizontal, 1.40-T magnetic field and is not attached to the wires in the circuit.
What is the magnitude of the acceleration of the bar just after the switch S is closed?

A random sample of n = 64 observations has a mean x = 29. 1, and a standard deviation of s = 3.9. Find a 90 % confidence interval for the population mean.. A major department store chain is interested in estimating the average amount its credit card customers spent on their first visit to the chain's new store in the mall. Fifteen credit card accounts were randomly sampled and analyzed with the following results: = $50.50 and = 400. Find a 95% confidence interval for the average amount the credit card customers spent on their first visit to the chain's new store in the mall.

You've decided to build a radio to listen to your favourite FM radio station, which broadcasts at 102.9 MHz. For the tuner, you'll be using an RLC circuit, but the only inductor you happen to have on hand has a value of 0.870 μH.
Unfortunately, there's another radio station — which you don't want to listen to — at a nearby frequency of 103.3 MHz. To prevent any interference from this 103.3 MHz radio station, you want the peak current from it to be no more than 0.160% of the peak current from your favourite 102.9 MHz station. What value of resistor should you use in your RLC circuit? (Assume the two stations have the same strength.)
Hint:You'll have to first calculate the value of the capacitor so that the radio tunes to 102.9 MHz.

CHAPTER 15(13.)
On January 1, 2018, Nath-Langstrom Services, Inc., a computer
software training firm, leased several computers under a two-year
operating lease agreement from ComputerWorld Leasing, which
routinely finances equipment for other firms at an annual interest
rate of 4%. The contract calls for four rent payments of $15,500
each, payable semiannually on June 30 and December 31 each year.
The computers were acquired by ComputerWorld at a cost of $101,000
and were expected to have a useful life of Five years with no
residual value. Both firms record amortization and depreciation
semi-annually. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of
$1 and PVAD of $1) (Use appropriate factor(s) from the
tables provided.)
Required:
Prepare the appropriate entries for both the lessee and the lessor
from the beginning of the lease through the end of 2018.
(If no entry is required for a transaction/event, select
"No journal entry required" in the first account field. Round your
intermediate calculations to the nearest whole dollar
amount.)

An ice cube of mass 11.4 g and initial temperature -6.0°C is held in your hand such that the water resulting from the melted ice reaches the temperature of your hand, 36.2°C. In order to accomplish this, how much heat (in kJ) must be absorbed by the ice cube and resulting water? Assume that all the water remains in your hand. Hint: Tables 14.1 and 14.2 in your textbook will be useful here.
