Answer: Batteries have three parts

Explanation:

Batteries have three parts, an anode , a cathode , and the electrolyte. The cathode and anode the positive and negative sides at either end of a traditional battery are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the anode.

A bar of 75 mm diameter is reduced to 73mm by a cutting tool while cutting orthogonally. If the mean length of the cut chip is 7

barxatty [35]

Answer:

r=0.31

Ф=18.03°

Explanation:

Given that

Diameter of bar before cutting = 75 mm

Diameter of bar after cutting = 73 mm

Mean diameter of bar d= (75+73)/2=74 mm

Mean length of uncut chip = πd

Mean length of uncut chip = π x 74 =232.45 mm

So cutting ratio r

$Cutting\ ratio=\dfrac{Mean\ length\ of cut\ chip}{Mean\ length\ of uncut\ chip}$

$r=\dfrac{73.5}{232.45}$

r=0.31

So the cutting ratio is 0.31.

As we know that shear angle given as

$tan\phi =\dfrac{rcos\alpha }{1-rsin\alpha }$

Now by putting the values

$tan\phi =\dfrac{rcos\alpha }{1-rsin\alpha }$

$tan\phi =\dfrac{0.31cos15 }{1-0.31sin15 }$ \

Ф=18.03°

So the shear angle is 18.03°.

In 2002 Acme Chemical purchased a large pump for

Anestetic [448]

Answer:

$151094

Explanation:

Solution

Recall that:

Acme Chemical in 2002 purchased a large pump worth of = 112,000

The estimation for the pump to the industrial pump index is =100

The index in 2002= 212

The current index is = 286

k = is the reference year for which cost or price is known.

n = the year for which cost or price is to be estimated (n>k).

Cn = the estimated cost or price of item in year n.

Ck = the cost or price of item in reference year k.

Cn = Ck * (In / Ik )

Now,

We find the estimated cost of the new pump which is stated as follows:

Cn = (112,000 * 286) /212

=32032000/212

=$151094

Therefore, the estimated cost of the new pump is $151094
