The correct answer is A; True.
Further Explanation:
This is a correct phrase that is important to learn when owning any type of vehicle. When a car battery is dead, it can usually be jump started by using another cars battery or a portable battery charger. It is extremely important to put the positive battery cable on the positive battery post. Then the negative cable will be placed on the negative car battery post and the negative ground wire can be anywhere on the car except on the battery.
The car needs to be connected properly for a few minutes before trying to start the car. This helps the car battery to get enough "juice" to start. If the battery cables are placed wrong this can cause sparks to come out of the cables/battery and cause bodily harm.

Answer:
The glass transition occur when the given temperature gets drop below the temperature of the glass transition for the polymers. During the creases of the long range of the given motion, the polymer start changing from the state of hard into the form of brittle.
The range of the glass transition temperature are between the 0 to -150°C. The basic use of the polymer is basically depend upon the main properties of the polymer.
Answer:
Divide the difference in tax by the amount of income from the investment, and you'll get the economic marginal tax rate from investing. Most people refer to marginal tax rates as being identical to tax brackets.
hope this helps
have a good day :)

Explanation:
a) The total number of users that can be accomodated in the system is:
![n = \frac{10\,km^{2}}{1\,\frac{km^{2}}{cell} }\cdot (100\,\frac{users}{cell} )](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B10%5C%2Ckm%5E%7B2%7D%7D%7B1%5C%2C%5Cfrac%7Bkm%5E%7B2%7D%7D%7Bcell%7D%20%7D%5Ccdot%20%28100%5C%2C%5Cfrac%7Busers%7D%7Bcell%7D%20%29)
![n = 1000\,users](https://tex.z-dn.net/?f=n%20%3D%201000%5C%2Cusers)
b) The length of the side of each cell is:
![l = \sqrt{1\,km^{2}}](https://tex.z-dn.net/?f=l%20%3D%20%5Csqrt%7B1%5C%2Ckm%5E%7B2%7D%7D)
![l = 1\,km](https://tex.z-dn.net/?f=l%20%3D%201%5C%2Ckm)
Minimum time for traversing a cell is:
![\Delta t_{min} = \frac{l}{v}](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmin%7D%20%3D%20%5Cfrac%7Bl%7D%7Bv%7D)
![\Delta t_{min} = \frac{1\,km}{30\,\frac{km}{h} }](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmin%7D%20%3D%20%5Cfrac%7B1%5C%2Ckm%7D%7B30%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D%20%7D)
![\Delta t_{min} = \frac{1}{30}\,h](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmin%7D%20%3D%20%5Cfrac%7B1%7D%7B30%7D%5C%2Ch)
The maximum time for traversing a cell is:
![\Delta t_{max} = \frac{\sqrt{2}\cdot l }{v}](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmax%7D%20%3D%20%5Cfrac%7B%5Csqrt%7B2%7D%5Ccdot%20l%20%7D%7Bv%7D)
![\Delta t_{max} = \frac{\sqrt{2} }{30}\,h](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmax%7D%20%3D%20%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B30%7D%5C%2Ch)
The approximate time is giving by the average of minimum and maximum times:
![\Delta t_{mean} = \frac{1+\sqrt{2} }{2}\cdot\frac{l}{v}](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmean%7D%20%3D%20%5Cfrac%7B1%2B%5Csqrt%7B2%7D%20%7D%7B2%7D%5Ccdot%5Cfrac%7Bl%7D%7Bv%7D)
![\Delta t_{mean} = \frac{1 + \sqrt{2} }{60}\,h](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmean%7D%20%3D%20%5Cfrac%7B1%20%2B%20%5Csqrt%7B2%7D%20%7D%7B60%7D%5C%2Ch)
c) The total number of users that can be accomodated in the system is:
![n = \frac{10\times 10^{6}\,m^{2}}{100\,m^{2}}\cdot (100\,\frac{users}{cell} )](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B10%5Ctimes%2010%5E%7B6%7D%5C%2Cm%5E%7B2%7D%7D%7B100%5C%2Cm%5E%7B2%7D%7D%5Ccdot%20%28100%5C%2C%5Cfrac%7Busers%7D%7Bcell%7D%20%29)
![n = 10000000\,users](https://tex.z-dn.net/?f=n%20%3D%2010000000%5C%2Cusers)
The length of each side of the cell is:
![l = \sqrt{100\,m^{2}}](https://tex.z-dn.net/?f=l%20%3D%20%5Csqrt%7B100%5C%2Cm%5E%7B2%7D%7D)
![l = 10\,m](https://tex.z-dn.net/?f=l%20%3D%2010%5C%2Cm)
Minimum time for traversing a cell is:
![\Delta t_{min} = \frac{l}{v}](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmin%7D%20%3D%20%5Cfrac%7Bl%7D%7Bv%7D)

![\Delta t_{min} = \frac{1}{3000}\,h](https://tex.z-dn.net/?f=%5CDelta%20t_%7Bmin%7D%20%3D%20%5Cfrac%7B1%7D%7B3000%7D%5C%2Ch)
The maximum time for traversing a cell is:
