28. Technician A says that during one four-stroke cycle of a cylinder, the crankshaft completes
one revolution. Technician B says that during one four-stroke cycle of a cylinder, the camshaft
completes one revolution. Who is wrong? Explain why?​

Answers

Answer 1
Technician A is wrong

Explanation:
During the intake stroke and compression stroke, the piston goes up and down once as it takes in the air and compressed it. The crank then makes another turn as the compressed fuel air mixture is combusted and the piston is forced down, then back up again through the exhaust valve. This makes the crankshaft complete more then one full revolution. The camshaft however is different. It takes a full turn when it opens the intake valve, closes it, opens the exhaust valve, closes it, and then comes back around again to complete the cycle. Each cycle takes one rotation of the camshaft due to the fact that the camshaft opens the valves. However, more then one full turn for the crankshaft as the piston has to go up and down a couple times in between this cycle. Thus, technician A is wrong.

"How would you direct traffic in the result of a catastrophic earthquake?"

Answers

Answer:

In the result of a earthquake, you should direct people into areas that are safe, such as places where the ground has not been broken up, and then tell people to get out of their cars and be careful. You should also have them carry any valuable items out of the car(if they have time), and then wait until the initial shocks and aftershocks are over, and then tell them to get back into their cars and then drive carefully and safely.

Answer:

You would tell people to get out of the way and stay safe.

When your driver license is _____, you will be prohibited from driving for a specified length of time
A. denied
B. suspended

Answers

When your driver license is suspended  you will be prohibited from driving for a specified length of time

The suspended license implies that your driver's license is temporarily revoked for a set length of time. By meeting certain criteria, you may be able to retrieve your license.

As per Indian country when you are caught speeding, the new law could suspend your license. Along with the suspension of the license, a minimum fine of Rs 1000 can be levied. The fine can be increased based on the car's speed and how far it exceeds the speed limit on that road.If your driving license is suspended, you will be unable to drive for an extended period of time.

Therefore, the final answer is "suspended"

What is the multiplicity of the root x = -4?

Answers

Answer:

See explanation

Explanation:

The multiplicity of  a root of a polynomial equation is the number of times the root repeats.

Let [tex]x=a[/tex] be the root of [tex]f(x)[/tex], then;

[tex](x-a)^1=0[/tex] has a multiplicity of 1.

[tex](x-a)^2=0[/tex] has a multiplicity of 2.

[tex](x-a)^3=0[/tex] has a multiplicity of 3.

[tex](x-a)^m=0[/tex] has a multiplicity of m, where m is a positive integer.

We were given the root [tex]x=-4[/tex].

If [tex]f(x)=(x+4)(x-6)^3[/tex]

Then the multiplicity of the root [tex]x=-4[/tex] is 1.

If  [tex]f(x)=(x+4)^4(x-6)^3[/tex]

Then the multiplicity of the root [tex]x=-4[/tex] is 4.

Since the polynomial function or equation is not given in the question, we cannot determine the multiplicity of this root.

But I hope with this explanation, you can refer to the original(complete) question and choose the correct answer.

Explanation:

To fix the ads at the bottom of your TCL TV, you might be seeing what is known as Featured Content or sponsored content. This is a common feature on smart TVs, including TCL models, which display advertisements as a way for manufacturers to offset the cost of the TV's smart capabilities.

Here are the steps to try and remove or minimize these ads:

Navigate to your TV's home screen and go into the settings menu.Look for options related to advertising, smart features, or home screen customization.Disable any options related to sponsored content, featured content, or advertisements.If there's an option to customize the home screen, try removing the ad placements or minimizing their visibility.Some TVs may allow you to opt-out of personalized advertising which could reduce the number of ads.

Should these steps not work, consider consulting the owner's manual or TCL's customer support for model-specific instructions. Please note that completely removing ads might not be possible on some models where this feature is built into the TV's user interface.

What is the lowest common denominator of 1/2 and 1/11

Answers

Answer:

22

Explanation:

2 and 11 are both prime so their GCF must be 2*11 which is 22.

For this case we have by definition, that the lowest common denominator of two or more fractions, is the number that results from calculating the lowest common multiple of the denominators of those same fractions.

We have the following fractions:

[tex]\frac {1} {2}[/tex] and[tex]\frac {1} {11}[/tex]

We look for the least common multiple of 2 and 11:

Two technicians are discussing the intake air temperature (IAT) sensor. Technician A says that the computer uses the IAT sensor as a backup to the engine coolant temperature (ECT) sensor. Technician B says that the powertrain control module (PCM) will subtract the calculated amount of fuel if the air measures hot. Who is correct

Answers

Both the technicians are correct.

Explanation

Intake air temperature sensor is used in engines of vehicles to monitor the temperature of air entering the engine.

They are basically made of thermistors whose electrical resistance changes according to temperature.

Depending upon the reading and accuracy of intake air temperature sensor, the power-train control module (PCM) will decide about the air and fuel mixture ratio in the engine.

The hot air in engine requires less fuel to operate the engine parts while cold air requires more fuel to operate the engine.

The ratio of air and fuel mixture should be maintained in the engine and it is done by PCM only after getting the input from IAT. So technician B is saying correct.

Also the IAT works as a backup to support the engine coolant temperature sensor by the computer.

As the IAT checks the temperature of outside air, it will help to change the coolant temperature of the engine based on the environment.

Thus technician A is also correct. So both the technicians are correct.
