Maglev trains were created to connect Shanghai Pudong International Airport to Central Pudong. Transrapid, another name for the Maglev train is said to be the fastest train. It can run up to 270/mph in just eight minutes.
Compared to other transportation systems, Transrapid is faster and more cost effective. It has less maintaining coverage and zero sounds compared to the ordinary ones. 
This kind of train is one of the most effective means of transportation. It lessens traffic and pollution caused by car emission. It also saves more time for people who are always on the go.

The atomic mass of chlorine is 17 give the electron configuration for a neutral atom of chlorine
Nana76 [90]
1s²2s²2p⁶3s²3p⁵

Explanation:
In writing the first two electrons will go in the 1s orbital.
Since 1s can only hold two electrons the next 2 electrons for chlorine go in the 2s orbital. 
The next six electrons will go in the 2p orbital.
The p orbital can hold up to six electrons.
 We'll pull six in the 2p orbital  and then put the next two electrons in the 3s.
Since the 3s is now full we'll move to the 3p where we'll place the remaining five electrons.

 Hope this helped ;)

A sheet of aluminum foil has a total area of 1.000 m2 and a mass of 3.636 g. What is the thickness of the sheet in millimeters?
olga2289 [7]

Answer:

t=1.34\times 10^{-3}\ mm

Explanation:

Given that,

Area of sheet of Aluminium foil is 1 m²

Mass of the sheet = 3.636 g

The density of Aluminium, d=2.699\ g/cm^3

We need to find the thickness of the sheet in millimeters.

The density of an object is given in terms of its mass and volume as follows :

d=\dfrac{m}{V}

V = volume, V = A×t, t = thickness of the sheet

So,

d=\dfrac{m}{A\times t}\\\\t=\dfrac{m}{Ad}\\\\t=\dfrac{3.636\ g}{10000\ cm^2\times 2.699\ g/cm^3}\\\\t=0.000134\ cm

Since, 1 cm = 10 mm

So,

t = 0.00134 mm

or

t=1.34\times 10^{-3}\ mm
