If there was anything you wanted to know about the Foster family all you had to do was look at Foster Family Central—the front of their refrigerator. Calendars, notes, photos, magnets, and schedules were stuck to the barely visible stainless steel doors.
The magnetic school calendar was positioned at the top with notations in most squares. The lunch menu was in a prominent place with big red circles around the Orange Chicken and French Toast Sticks selections. Cameron's baseball photo magnet was on top of the announcement titled, "District Spelling Bee Wednesday." And right above the ice dispenser was Connor's spring soccer schedule.
As messy as the refrigerator looked on the outside, it made a statement about the Foster family and their busy lives. It was the only place that all six family members gathered to get a snapshot of what the day ahead would be like.
When 12–year old Chandler came home from school on Wednesday he went straight to the fridge to find a snack. He stuck his head in and announced, "There's no food to eat." He opened one drawer and found a piece of cheese that looked like a science experiment. Then he held up a plastic bag with a chicken leg in it that looked like it was wearing fur.
"Are you going to get ready for the Spelling Bee?" Dad walked in from the garage, setting his briefcase on the counter.
"I am very nervous and I wish there was something in the fridge to eat," said Chandler. He competed against 40 students and qualified for the District Spelling Bee.
"What time do you need to be at school?" Dad asked. Chandler took the flyer off the fridge, dropping several notes and magnets to the kitchen floor. "I need to be there at 5:30," Chandler stated. "I have a soccer game at 5:00," Connor said. Dad looked at the soccer schedule and sure enough, there was a game at 5:00.
Mom walked in and asked who was going to pick up Kendall at day care before they closed at 6:00.
Five members of the Foster family sat at the kitchen table trying to come up with a plan to make sure that Chandler made it to school for the Spelling Bee, Connor got to the field for his soccer game, and Kendall was picked up from day care before they closed. After making some notes, Dad came up with a plan that involved six people, three different locations, and one car and one van.
When Cameron got up from the table and walked by the refrigerator, his leg brushed against the door and magnets holding schedules all dropped to the wood floor.
"Hey Dad," Cameron said, "Maybe you can come up with a plan for keeping these papers from falling."
"I already have – I'm going to put everything in my electronic organizer!" Dad joked.
A.
His fear of letting his children down caused Chandler to be late for the Spelling Bee.
B.
His patience allowed him to calmly sit down with his family and come up with a plan to solve the problem.
C.
His laziness caused all of the children to be late for their events.
D.
His uncertainty made it impossible to come up with a plan to solve the problem.

Answer:
(C) 400000
The product of the place values of two 2’s in 428721 is
There are two 2’s in the given number. So, the first 2 is in the tenth place, Then, the product is = 2 × 10= 20
The other 2 is in place value of ten thousand. Then, = 2 × 10000= 20000 Therefore, the product of place values = 20 × 20000= 400000
Explanation:
In the diagram above the ammeter is connected across the terminals of the 20v battery in parallel with the 10 ohm resistor. Most likely the ammeter will be at full deflection, as it will be functioning as a voltmeter.
Ammeters are used to measure current (measured in Amperes.) In order to measure a current we must measure the current THROUGH something. For purposes of experimentation and schematic drawings, we make the assumption that the interconnecting lines (representing wires or other connections) have no resistance. In real life though, all materials have resistive properties although some such as most metals have extremely low values.
Unfortunately the diagram doesn’t give us more information. For example, we don’t know the internal resistance of the ammeter. Internally an ammeter has a small resistance owing to the many turns of wire in the coil. There usually is also an internal (or external) “shunt” resistor. In my very first circuits class in college, one of our exercises was to calculate the internal resistance of a meter using known resistance.
If the ammeter was connected is SERIES (see diagram below) with the 10ohm resistor (instead of parallel) then we could use Ohm’s Law to figure out the current: I=E/R. I=current in Amperes, E=potential in Volts and R=resistance in Ohms.
