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.
There are different reasons why we should about these high voltage system or are; The reason is that;
Because high voltages often reduce the impedance of our skin, thereby making electricity to flow through our bodies.Learn more about Voltage from

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

How much current is drawn by a flashlight that has a resistance of 10 ohms if a voltage of 3 volts is impressed across it?
Answer:
0.3 amps
Explanation:
amps can be found using the equation
current=volts/resistance
so current=3V/10Ohms=0.3 amps
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?
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.
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

A technician notes that an operating air-conditioning system has ice formed on the suction line at the condensing unit. The technician can reasonably assume that:
The technician can reasonably assume that evaporator coil is frozen over.
An air-conditioning system makes a place cooler by absorbing heat from the
surrounding. This is usually done with the aid of the evaporator coil.
In situations whereby there are ice particles formed on the suction line at the
condensing unit then it means the air conditioning system is faulty and must
be turned off to prevent damage to other parts.

(b) The application of user centred design can lead to innovative products such as the umbrella shown in Figure 9.
Explain the concept of user centred design and how it may have influenced the design of the umbrella shown in Figure 9. (6 marks)
Answer:
the concept of user centred design is the idea of putting your clients best needs in mind. you need to be empathic and understanding of how to make their life easier. by doing research you can do this. for example the design in figure 9 shows an umbrella with a canopy. the canopy can deflect rain and still have the easy design of an umbrella. this makes it not only easier to use but functional.
