<h2>Answer</h2>

<u>Density is the mass per unit volume</u>

<h2>Explanation</h2>

Density is actually is the ratio of the mass of an object to its volume. It is used to compare the different objects on the basis of their weight. You can say that more the weight of an object more will be its density. For example, the density has the role in floating the ships on the water. When we insert the wooden piece inside water it pops up to the surface. The weight of the wood piece is more than the water and volume is greater which affects its density. When the object gets smaller the size on pressing, the density of the object increase.

Nikolay [14]

Answer:

OPTION A, Kelvin Thermometer is Incorrect

Explanation:

Now, if you consider best two out of three results, then celsius and Fahrenheit thermometers read the same value, meaning both are right.

1) K = °C + 273

K = 100°C + 273

k = 373°C

Kelvin Thermometer is Incorrect

2) C = \frac{F - 32}{1.8}

when we have 212°F

C = \frac{212 - 32}{1.8} \\\\= 100^\circ C

which is correct

The inductance of a closely packed coil of 560 turns is 8.9 mH. Calculate the magnetic flux through the coil when the current is
Y_Kistochka [10]

Answer:

0.11\times 10^{-6}weber

Explanation:

We have given number of turns N = 560

Inductance L = 8.9 mH

Current through the coil = 7 mA

Inductance of the coil is given as L=\frac{N\Phi }{I}

Where N  is number of turns I is current and \Phi is flux

So \Phi =\frac{LI}{N}=\frac{8.9\times 10^{-3}\times 7\times 10^{-3}}{560}=0.11\times 10^{-6}weber
