what are the advantages and disadvantages of a mine heardgear
Answer:
If there is a shaft with headgear, then mining can take place until that depth of the shaft. If it is accessed horizontal Adits, it can mine until the lowest Adit from upwards. If it is accessed decline, the development and mining can continue so long as economic exploitation is possible.

4. What is stranded energy in an EV situation?
A) When there is stored energy in the battery after an accident that has caused damage to the protective case or
wiring harness
B) O Energy that is produced when an EV has been sitting idie for a number of months
When the driver runs out of charge while driving
DIO Energy left after a full charge at a charging station
A stranded energy in an EV situation is: A) when there is stored energy in the battery after an accident that has caused damage to the protective case or wiring harness.
What is a charge?A charge can be defined as a fundamental, physical property of matter that governs how the particles of a substance are affected by an electromagnetic field, especially due to the presence of an electrostatic force (F).
In Engineering, charge is typically measured in Coulombs. For instance, a charm quark (elementary particle) or battery has a charge that's approximately equal to 1.07 × 10⁻¹⁹ Coulomb.
What is a stranded energy?A stranded energy can be defined as the stored electrical energy in damaged battery (lithium-ion) cells that is remaining after efforts to safely discharge it.
In conclusion, a stranded energy in an EV situation is when there is stored energy in the battery after an accident that has caused damage to the protective case or wiring harness.

Name a device that uses a control knob to set the level of something
A "volume knob" on an audio device refers to a device that uses a control knob to adjust something's level.
Thus, Users can change the sound level by turning up or down the volume of the audio output through speakers or headphones.
On gadgets like radios, amplifiers, televisions, music players, and other audio equipment, it is frequently observed.
Users can adjust the volume to their preferred level by rotating the volume knob either clockwise or counterclockwise. Audio mixers are frequently employed in a variety of applications, including broadcasting, live sound reinforcement, and music production.
Thus, A "volume knob" on an audio device refers to a device that uses a control knob to adjust something's level.

Explanation:
How often does a 4-stroke engine make power to turn the crankshaft?
Answer:
A 4-stroke engine fires once every second rotation of the crankshaft (every fourth stroke of the piston).
Answer:
Every 4 strokes of the piston, or every 2 full rotations of the crankshaft.
Explanation:
The 4 strokes are most commonly known as Suck, Squeeze, Bang, and Blow (don't laugh, this is serious.) Suck (intake of fresh air and fuel) and squeeze (compressing the air/fuel mixture) are both parts of the first full rotation of the crankshaft, then bang (igniting the fuel and air mixture) and blow (expelling the exhaust gasses from the cylinder) are parts of the second full rotation of the crankshaft. Then this cycle repeats for as long as power is required, or until there is no more fuel to be mixed with the air, or there is no longer any ignition.

What is the resistance of a resistor if the current flowing through it is 3mA and the voltage across it is 5.3V?
Answer: 1766.667 Ω = 1.767kΩ
Explanation:
V=iR
where V is voltage in Volts (V), i is current in Amps (A), and R is resistance in Ohms(Ω).
3mA = 0.003 A
Rearranging the equation, we get
R=V/i
Now we are solving for resistance. Plug in 0.003 A and 5.3 V.
R = 5.3 / 0.003
= 1766.6667 Ω
= 1.7666667 kΩ

C) Both A and B.
D) Neither A nor B.
The true options when describing an air ratchet is C) Both A and B.
A) Most do not require impact sockets.
B) Operate at a higher rate of speed than an impact wrench.
What is air ratchet?An air ratchet is a tool that uses air power to help fix cars and do other mechanical jobs. Both statements A and B are correct when talking about an air ratchet tool.
Air ratchets are made to work with regular sockets, not impact sockets. Air ratchets are different from impact wrenches because they are not as strong and do not need as much force. They are good for jobs that don't need a lot of power.
