Answer:
a) 20 Ω
b) 1 A
c) 10 V on each
d) 1/3 A through each
e) 10 W in R1, 3 1/3 W in the others
f) 20 W
Explanation:
The three 30 Ω resistors are in parallel with each other, so will have an equivalent resistance of (30 Ω)/3 = 10 Ω.
(a) The total circuit resistance is 10 Ω + 10 Ω = 20 Ω.
__
(b) All of the current supplied by the battery passes through R1. The current supplied by the battery is ...
I = V/R = (20 v)/(20 Ω) = 1 A
__
(c) The voltage drop on R1 is (1 A)(10 Ω) = 10 v. Subtracting that from the battery voltage gives the voltage drop on the other resistors:
20 v -10 v = 10 v . . . . drop on R2, R3, R4
__
(d) The current through resistors R2, R3, R4 is ...
I = V/R = (10 v)/(30 Ω) = 1/3 A
__
(e) Power can be computed several ways. Here, it may be easiest to use ...
P = VI
For R1, that is P1 = (10 v)(1 A) = 10 W
For R2-R4, that is P2-P4 = (10 v)(1/3 A) = 10/3 W = 3 1/3 W
__
(f) The total power dissipated is the total power supplied:
P = VI = (20 v)(1 A) = 20 W
Adding up the power in the resistors, we get ...
P = 10 W + 3·(10/3 W) = 20 W

why are you directed not to touch the holder or discharge tube whule the power to the supply to the gas tube is on?
Answers
Every profession has its rules and regulations. The reason why we are directed not to touch the holder or discharge tube while the power to the supply to the gas tube is on because;
The discharge tube can create about 5000 V of voltage when connected to power.The gas discharge tubes is often very hot when used with the power supplies and one should not to touch them until they are cooled down.
We have been taught to stay far was from a high voltage area or system and also we should not dare to touch it.

Gasoline has a comparatively high Btu per gallon rating of around
Select one:
O a. 1 lb: 2°F
O b. 5,000 Btu
O c. 12,000 Btu
O d. 14.000 Btu
Answers
Answer:
A
Explanation:
Gasoline has a comparatively high Btu per gallon rating of around 1 lb: 2°F. GGE enables customers to contrast the energy value of competing fuels with gasoline, a widely used fuel. Thus, option A is correct.
The term "gasoline gallon equivalent" (GGE) or "gasoline-equivalent gallon" (GEG) refers to the volume of an alternative fuel needed to produce one liquid gallon of gasoline's equivalent amount of energy.
If fuels are offered in various quantities and in various physical forms, it is challenging to compare the price of gasoline with other fuels. GGE tries to address this. The energy content of one gallon of gasoline is exactly equal to that of one GGE of CNG and one GGE of electricity. GGE does this by directly contrasting gasoline with other alternative fuels, such as those offered as gas (natural gas, propane, and hydrogen) and as metered electricity.
Therefore, option A is the ideal selection.

John has an exhaust leak in his Acura Integra GS-R, What steps would he take to fix the leak in time for his inspection?
Answers
Answer:
Explanation:
Fist you need to identify where the leak is coming from. You can do this by either listening for the leak or spraying soapy water on the exhaust to look for air bubbles coming out of the exhaust. Depending on the spot of the leak there are many ways you can fix this leak.
1. Exhaust clamp
2. Exhaust putty
3. Exhaust tape
4. New exhaust
Exhaust clamp is best used for holes on straight pipes.
Putty is best used on welds or small holes like on exhaust manifolds or welds connecting various pieces like catalytic converters, mufflers, or resonators.
Tape will work best on straight pipes with holes.
New exhaust is for when the thig is beyond repair, like rust.
Now good luck because working on exhausts is a pain.

Nicole and Josie are both selling cookie dough for a fundraiser. Although Nicole has already sold 4 tubs, Josie hasn't sold any yet. If Nicole starts selling 5 tubs per day and Josie begins selling 6 tubs per day, they will eventually sell the same amount of cookie dough. How many tubs will each sell? How many days will that take?
Nicole and Josie will each sell
tubs of cookie dough in
days.
Answers
The number of tubs that each of them sold is; 24 tubs each
The number of days it will take for both of them to sell same amount of tubs is; 4 days
Number of cookies that Nicole had already sold = 4 tubs
Number of cookies sold by Josie before counting = 0 cookies
Nicole now sells 5 tubs per day and
Josie now sells 6 tubs per day.
Let the number of days it will take for them to have sold the same amount of cookies be d.
Thus;
5d + 4 = 6d + 0
6d - 5d = 4
d = 4 days
Thus, total number of cookies for both are;
Total for Nicole = 4 + 5(4) = 24 cookies
Total for Josie = 6(4) = 24 cookies
