Answer 1

Answer:

I wrote 40 MPa for this question.

Explanation:

I know that 1 MPa = 1 N / mm^2 so I converted kN to N and mm^2 to cm^2. This helped me use the equation to solve.

find the first principle derivative for 3/x with respect to x.​

Answers

Answer:

-3/x^2

Explanation:

Deriving is a lot like taking one away from the exponent. With that in mind, lets rewrite 3/x into 3x^-1. All we need to do is bring down the negative one then subtract one from the exponent. This gives us -3x^-2. We can convert it back to -3/x^2 .

A carbon resistor has a resistance of 976 ohms at 0 degrees C. Determine its resistance at 89 degrees C​

Answers

Answer:

1028.1184 Ohms

Explanation:

Given the following data;

Initial resistance, Ro = 976 OhmsInitial temperature, T1 = 0°CFinal temperature, T2 = 89°C

Assuming the temperature coefficient of resistance for carbon at 0°C is equal to 0.0006 per degree Celsius.

To find determine its new resistance, we would use the mathematical expression for linear resistivity;

[tex] R_{89} = R_{0} + R_{0}(\alpha T) [/tex]

Substituting into the equation, we have;

[tex] R_{89} = 976 + 976*(0.0006*89) [/tex]

[tex] R_{89} = 976 + 976*(0.0534) [/tex]

[tex] R_{89} = 976 + 52.1184 [/tex]

[tex] R_{89} = 1028.1184 \ Ohms [/tex]

If you are traveling over 50 miles per hour, then you should signal at least this far before your turn

Answers

Answer: 300 ft

Explanation:

This question is based on Indiana State Driving codes.

According to Indiana regulations, if you are going at a speed of 50 miles per hour or above, you should begin to indicate your desire to turn or change lanes at least 300 feet before you do.

This would give the person behind you ample time to react as they might be going at the same speed as you. The rules further state that the signal to use is that of the car but if it is damaged then hand signals would suffice.

Calculate the minimum area moment of inertia for a rectangular cross-section with side lengths 6 cm and 4 cm.


52 cm4


72 cm4


32 cm4


24 cm4


2 cm4

Answers

Answer:

Part 1

4 mm⁴

Part 2

32 cm³

Explanation:

Part 1

The diameter of the circular cross section, d = 3 mm

The area moment of inertia of a circle, [tex]I_C[/tex], is given as follows;

[tex]I_x = I_y = \dfrac{\pi \cdot d^4 }{64}[/tex]

Where;

d = The diameter of the circle

Therefore, the area moment of inertia of the given circular cross section, with d = 3 mm, is found as follows;

[tex]I_x = I_y = \dfrac{\pi \times (3 \, mm)^4 }{64} \approx 4 \, mm^4[/tex]

Part 2

The minimum area moment of inertia for a rectangular cross-section is given as follows;

[tex]I_x = \dfrac{1}{12} \cdot b \cdot h^3[/tex]

[tex]I_y = \dfrac{1}{12} \cdot h \cdot b^3[/tex]

The minimum moment of inertia, for the rectangular cross-section is given by placing, the height, h = The short side length and calculating for, Iₓ, and vice versa

Therefore, for the question, where, h = 4 cm, and b = 6 cm, we have;

[tex]I_x = \dfrac{1}{12} \times 6 \, cm \times (4 \, cm)^3 = 32 \, cm^4[/tex]

When vehicle wheels are about to lock, the ABS senses the impending lock up and prevents this from occurring. a) True b) False 2 Question 2 Electronic stability control reduces the risk of rollover crashes, such as are common with SUVs. a) True b) False 3 Question 3 _______________have the ability to control wheel lock on all four tires. a) Four-wheel anti-lock brakes b) Rear-wheel anti-lock brakes c) All anti-lock brakes d) None of the above

Answers

Answer:

1. a) True

2. a) True

3. a) Four-wheel anti-lock brakes

Explanation:

1. True

When a wheel skids, there is less traction with the road and the vehicle is out of the driver's control

Breaks that have ABS are prevented from functioning fully in a situation where the contact between the tire and the road patch is broken and the tire is able to skid. Once the tire regains and maintains proper contact with the road surface such that the skidding has ceased, the full functionality of the brakes are restored, enabling the moving vehicle to stop faster and the steering to remain operational

2. True

A vehicle that has a standard Electronic Stability Control, ESC, is less likely to rollover. According to a University of Michigan Transport Research Institute study, SUVs equipped with an ESC are 73% less likely to have fatal rollover crashes

3. a) Four-wheel anti-lock brakes

The four-wheel anti-lock *four-wheel ABS) brakes works such that each wheel has a sensor through which if is detected that the wheel is about to lock, the ABS, ESC releases the break pad on the wheel such that the wheel keeps spinning

A Bee MysteryRecent surveys around the world have found some very sad and troubling news. Bees are not doing well. According to Time: Science & Space, "an estimated ten million beehives ... have been lost since 2006." What's worse, scientists are not sure why. Most beekeepers will tell you that bees tend to die in large numbers every spring. This is normal and necessary to keep a hive of bees healthy. But when the deaths add up to more than half the bees in an entire country, that is something altogether different and dire. Scientists have called this "colony-collapse disorder" or CCD. This name describes the effect, though, and not the cause of the die-out. Scientists simply do not know what is killing the bees.Many things make it hard for bees. Varroa mites move into a colony and weaken it. Further, these mites carry viruses that attack those that survive. In addition, a new bacterium was recently discovered that attacks bees intestinally and kills them. Beekeepers go to great lengths to protect bees from these invaders, and for many years have been able to control them. All these attackers and the methods used to combat them do stress the bees, however.Many feel the problem is not some new threat, but a decline in the habitat available to bees. Development of grasslands once home to wild flowers and food for bees has been universal. Pavement makes it easy to drive, but it replaces wild grasses and other food sources for bees. Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health. We plowed under a varied habitat and plantedin many casesa single plant like beets. Then we sprayed all kinds of chemicals on the beets to keep other bugs away and in doing so also harmed bees. Now, to treat all the mites and other invaders, bee keepers use additional chemicals to kill the invaders. These chemicals also shorten the life of the bees. Have the use of chemicals, loss of habitat, and invading parasites made life impossible for bees? Experts continue to argue various theories, but few have any answers.Colony collapse disorder is perhaps one of the most mysterious problems modern science has tried to solve. Whether the problem is environmental or an unknown disease, we will all feel the effects if bees continue to decline. Bees affect almost every aspect of the human food chain. From the fruits, vegetables, and grains we eat, to the grasses and grains we feed our livestock, we depend on bees to keep us healthy. According to the Natural Resources Defense Council, bees account for 15 billion dollars in crops. Honey is a treasure for sure, but the real gold is in the strawberries, apples, peaches, and green beans we eat and need to stay healthy ourselves. All told, the outlook for bees is not good. The outlook for humans may not "bee" so good either.Read this sentence from the text:Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health.How does this line function in the text?
