Answer:The outer core of the Earth contains a lot of iron in a molten state. As the Earth spins this molten iron moves and creates the Earth's magnetic field. The Earth behaves as if there is a huge bar magnet at its centre. The shape of the field around the Earth is very similar to the field around a bar magnet
Explanation:
Mass of a sample = M = ?
Density of a sample = D = 8.9 g/cm³
Volume of the sample = 6 cm³
By using the formula = D = M / V
Density = Mass / Volume
Mass = Density x Volume
M = D x V
Putting the values of density and mass of the sample
M =8.9g/cm³ x 6cm³ =53.4 g
<span>So, the mass of the material in grams is 53.4g</span>
In absolute value it is equal to 906,060
In scientific notation it is equal to -9.06,060^5
Answer:
Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
Explanation:
The types of bonds present are:
a) Ethane : single bond
b) Ethene : double bond (one sigma one pi)
c) Ethyne: triple bond (one sigma and two pi bonds)
More the number of bonds lesser the bond length.
Thus the order of bond length of carbon-carbon bond will be:
Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
