11. 0.12amperes
12. 2.88watts
Explanation:
1. Solving the parallel connections,
1/2+1/7= (7+2)/14
9/14
Resistance= 14/9
1/4+1/9= (9+4)/36
13/36
Resistance=36/13
Total resistance in the circuit= 3+14/9+ 36/13
(351+182+ 324)/117
857/117= 7.32ohms
2. V=IR
I= V/R(total resistance)
I= 12/7.32
I= 1.64amperes
3. V= IR
for the 3ohms resistors, V= 3×1.64
=4.92volts
Voltage is the same for resistors in parallel
Current is the same for resistors in series
for the parallel resistors 2ohms and 7ohms,
V= 1.64 × 14/9
= 2.55volts
for the parallel resistors 4ohms and 9ohms,
V= 1.64× 36/13
= 4.54volts
4. For parallel resistors R2 and R3,
1/30+1/50 = (50+30)/150
80/150
Resistance= 150/80
Total resistance= 20+150/80+20
(1600+150+1600)/80
3350/80= 41.875ohms
5. V= IR
I= 10/41.875
= 0.2388amperes
6. for the 20ohms resistor,
V= 0.2388×20
V=4.776volts
for the parallell resistors 30ohms and 50ohms,
V= 0.2388×150/80
= 0.4478volts
for the 20ohma resistor,
V= 0.2388×20
= 4.776volts
7. R6+R7 = 2+2
= 4ohms
1/4 + 1/R5
1/4+1/4=(1+1)/4
2/4= 4/2
=2ohms
2+R4= 2+10
=12ohms
R2 +R3= 4+8
=12
1/12+1/12= 2/12
12/2=6
6+R1= 6+4
total resistance= 10ohms
8. V=IR
I= 5/10
=0.5amperes
9. For R1
V= 0.5×4
=2volts
for 6ohms effective resistance
V=0.5×6
=3volts
For R2 and R3
V=IR
3=I×12
I=0.25
In R2
V=0.25×4
=1Volt
In R3
V=0.25×8
=2volts
0.5-0.25=0.25amperes
In R4
V=0.25×10
=2.5volts
for the 2ohms effective resistance,
V=0.25×2
=0.5volts
In R5
v= 0.5volts
I= 0.5/4
= 0.125amperes
current in R6 and R7
0.25-0.125=0.125amperes
In R6
V=0.125×2
=0.25volts
in R7
V=0.125×2
=0.25volts
10. for R1 and R2
1/100+1/250
(5+2)/500= 7/500
500/7= 71.43ohms
for R3 and R4
1/350+ 1/200
(4+7)/1400=11/1400
1400/11=127.27ohms
total resistance= 71.43+127.27
= 198.7ohms
11. V=IR
I= 24/198.7
=0.12amperes
12. Power= IV
power= 0.12×24
=2.88watts

Read the passage.
Children today spend more time using computers, phones, and tablets than children did in the past. This means that youngsters tend to be less physically active now than before. At the same time, there has been an increasing awareness of the importance of exercise. Recent research has supported the idea that brain development and physical development go hand in hand. National Physical Activity Plan guidelines suggest that every young person engage in at least 60 minutes of physical activity a day.

Answers
Dave had a hard time giving back how much money he had spent on his vacation.
What is Money?Money drives the global economy. The basis of economies is the exchange of money for goods and services. Economists define money, along with its source and value.
Money is any tangible item or verifiable document that is regularly accepted as payment for goods and services as well as the settlement of debts, such as tax obligations, in a particular country or socioeconomic environment.
The four main uses of money are as a store of value, a unit of account, a means of trade, and sporadically as a benchmark for delayed payment. Money can be any tangible item or verifiable document that fulfills these requirements.
What is Vacation?A vacation, or holiday in British and American English respectively, is either a leave of absence from a normal work or a trip taken for leisure away from home.
People frequently go on vacation for certain festivals, celebrations, or holiday observances.
Family or friends are frequently present during vacations. A trip or travel can be included in a vacation, typically for leisure or tourism.
Hence, option A is correct.
