What are the risks of biohacking? Do you think the risks of biohacking outweigh the advantages? Why or why not?
Explanation:
Despite its futuristic outlook and results biohacking remains a largely unsupervised, dangerous if not illegal movement. Though the research and results produced by biohackers is ground breaking, it also breaks several ethical codes on human experimentation and endangering live of several humans.
I agree with the fact that risks outweigh advantages, but you can do things like:
- 3D Printing Body Parts
- Finding Cures
- Correcting Deformites.
The only issue is that it's illegal, unfortunately.

please tell us about your biggest success solving any mechanical issue
Explanation:
My biggest success solving any mechanical issue is learning how to use a wheelchair and making it easier for my sibling to move around.
Since my sibling broke her legs permanently, I felt terrible and wanted to do something to help out. My hallways were very small, so I wanted to make it easier for her to get around. I asked my parents if we could take down an unneeded wall in the hall, and so we did.
I calculated a bunch of thingies, and soon, my sibling could get around the house with ease, which really made me feel a lot better.

Explanation:
the great pyramid of khufu (giza, egypt) is about 140m tall. How much work would be required to raise an average - sized pyramid black (2.5 tons) to this height?
Answer:
3.43 MJ
Explanation:
The work required to raise a 2500 kg block to a height of 140 m is ...
W = Fh = (mg)h
= (2500 kg)(9.8 m/s²)(140 m) = 3,430,000 kg·m²/s²
= 3.43 MJ
The work required is 3.43 megajoules.
_____
Additional comment
Reportedly, a motivated human performing manual labor can sustain a power output of about 75 watts. At that rate, it would take about 12.7 hours of continuous effort for one person to lift the block to that height.
Answer:
3.43 MJmuch work should be required to raise an averaged sized pyramid black(2.5 tons) to this height.How are the scientific method and the engineering method similar?

any one know the diffrence in a 12v and 24v cummins?
other than the time peorides and the number of vaulve rods
whats the better one?
please dont answer unless u know adout cars
(and Yes katie this is educational)
Explanation:
The 24v is a higher-revving motor, thus you'd probably want the 4:10. The 12v has better low-end grunt and wont spin as fast, so the 3.54 would work better. Bombing is easier with the computer trucks, and cheaper with the mechanical trucks.
24V are much louder than a 12V at the engine.
While the 12-valve is a little bit more reliably with the mechanical P7100 pump, tuning it requires modified parts of the injection pump. The 24-valve might not be as insanely reliable, but it's still very reliable and can easily be tuned with a handheld tuner.
A gasoline engine transforms
_____energy into
_____energy for doing useful work.
Answer:
A gasoline engine transforms approximately 34% of the fuel's chamical energy into mechanical energy.
Explanation:
Many forms of combustion are examples of converting chemical energy into mechanical energy. Chemical energy is locked in the bonds of any combustible material: Gasoline, kerosene, wood, black powder.
Shooting off fireworks, igniting that bottle rocket converts the fuel inside into an exhaust gas which propels the rocket. Pulling the starter cord on your lawn mower ignites the fuel, releasing the energy that drives your lawn mower.
Automobiles, trains, planes all have combustion engines. Jet planes burn fuel more like a rocket engine, using the force generated by directed explosive gases.
The more interesting of this basic conversion principle today is in trying to create the stored chemical energy from mechanical energy. In other words, converting mechanical energy into clean fuel. One of the easiest to see is the use of wind power to produce the mechanical energy to create a DC energy and using that DC energy produce hydrogen from water via the process of electrolysis:
The wind drives the mechanical device that essential rotates a conductor through a magnetic field creating the DC voltage used to separate the hydrogen and oxygen. That mechanical to chemical conversion produces a pure hydrogen which has much more combustion potential energy than an equivalent mass of gasoline.

What are probiotic bacteria and how did Danino and his team use this type of bacteria to detect liver cancer?
Explanation:
Probiotics are a combination of live beneficial bacteria and/or yeasts that naturally live in your body. Bacteria is usually viewed in a negative light as something that makes you sick. However, you have two kinds of bacteria constantly in and on your body — good bacteria and bad bacteria.
Using a harmless strain of E. coli that colonizes the liver, the researchers programmed the bacteria to produce a luminescent signal that can be detected with a simple urine test.
Discuss where Danino says bacteria grow can grow in your body. Why is it more easily able to live there, as opposed to other areas of the body?
Answer:
Danino says bacteria can grow in tumors in your body. It is easier to live there because they see it as their safe haven. The bacteria is safe there unlike in other parts of your body the bacteria will get filtered out.
Explanation:
The main reason why it is more easily able to live in tumors, as opposed to other areas of the body is:
They can stay and reproduce there without being filtered out by the body.What is Bacteria?This refers to the unicellular organisms which live in the body of a living or non living thing.
With this in mind, we can see that Danino was of the opinion that bacteria finds their safe haven inside tumors in the body because they feel safe and cannot be easily removed.

The MAP sensor's vacuum hose is loose and cracking. Technician A says this sensor measures air mass to establish the fuel injector's base pulse width. Technician B says this sensor measures changes in intake manifold pressure. Who is correct
Answer:
Both A and B
Explanation:
The Engine's electronic Control Unit (ECU) gets the instantaneous manifold pressure data from the Manifold Absolute Pressure or MAP sensor which it uses to determine the air density such that the proper engine air mass flow rate is also determined, and from which the allowable fuel flow rate for optimum combustion is established
As such the MAP sensor measures the air mass to establish the fuel injector's base pulse width, which controls the fuel delivery. The MAP sensor also measures intake manifold which is related to the density of the air.
A disc brake rotor is being machined. Technician A says that a feed rate of 0.0008 inch per revolution and 150 RPM is where the rotor should be set for a final cut. Technician B says that the rotor should be given a non-directional surface finish using 150 grit sandpaper. Which technician is correct?
Answer:
Technician B only
Explanation:
During rotor reconditioning, which is the process also known as machining and sanding, where sanding is the involves the application of between 120 and 150 grit sandpaper while using a non-excessive force that is applied non-directionally for up to 60 seconds on each side such that the surface roughness meets OE standards. The rotors are then cleaned by washing after they are serviced before they can then be installed.

Answer:
c 45 feet from the fulcrum
Explanation:
The moment at the fulcrum must be the same for each car. If the distance is d, then the artist must have ...
(2100 lb)(30 ft) = (1400 lb)(d)
2100·30/1400 ft = d = 45 ft
The Volkswagen should be 45 ft from the fulcrum.

Answer:
During installation, the air transformer should be located at least 25 feet minimum from the compressor unit
Explanation:
An air transformer is used to remove the dirt, water and oil in the compressed air and to filter as well as to provide air regulation and are required in spray finishing tasks that calls for a regulated clean and dry supply of air
The air transformer measures the pressure of the regulated air and can also come with air outlets for air operated tools, blow guns, spray guns, as well as for other purposes
In order to operate efficiently, the air transformer are required to be installed at a minimum distance of 25 feet (7.6 m) from the compressor unit.
Summarize the difference in hydraulic and pneumatic systems.
Answer:
The main difference between a pneumatic system and a hydraulic system lies in how the energy necessary to make these systems work is generated: thus, while in the pneumatic system this energy is generated through the compression of gases, in the hydraulic system the energy is obtained Through the insertion of pressurized fluids, such as water. Furthermore, hydraulic systems are closed circuits, where the water constantly circulates within the system; while in pneumatic systems the air that is compressed and used is constantly renewed.
