Physics

The name of this SI Unit Henry is derived from the name of the scientist who discovered the concept of inductance and electromagnetic induction, Joseph Henry. He was a scientist from America who supported the principles of Faraday and helped in bringing a revolution in the field of modern physics.

Distance travelled by the body = Sum of areas under the curve (both below and above x-axis)

$\frac{1}{2}*3*10*2$

$=30m$

${}_Z{}^{A}X+{}_1{}^{1}H\to {}_2{}^{4}He+{}_8{}^{16}O$

$Z+1=2+8?Z=9X\to F$

$A+1=4+16\Rightarrow A=19$

$\Rightarrow {}_Z{}^{A}X={}_9{}^{19}F$

${}_7{}^{14}N+{}_Z{}^{A}Y\to {}_1{}^{1}H+{}_6{}^{14}C$

$7+Z=1+6?Z=0$

$14+A=1+14?A=1$

$?{}_Z{}^{A}Y={}_0{}^{1}n$

The spectrum of H-atom is formulated and drawn by Bohr's model. These spectrums are line spectrum. Lyman series lies in UV region, Balmer Partly lies UV and partly in the visible region and Paschen series lies in the infrared region.

In intrinsic semiconductors, conductivity is mainly due to breakage of covalent bonds in extrinsic semiconductors, the conductivity is due to the addition of impurities.

On repetitive use of NAND GATE or NOR gate, any logic GATE can be prepared.

Unit of temperature is Fahrenheit

Unit of mass is atomic mass of unit

Unit of length is light year

Unit of time is shake

In a measurement, a choice of change of different units does not change the number of significant figures.

Frequency in the stretched wire is

$f=\frac{1}{2l}\sqrt[]{\frac{T}{\mu }}$

$f_1^2=\frac{T_1}{4\mu l^2}$

$f_2^2=\frac{T_2}{4\mu l^2}$

$\frac{T_1+T_2}{4\mu l^2}=f^2$

$f^2=f_1^2+f_1^2$

$f=\sqrt[]{{\left(80\right)}^2+{\left(150\right)}^2}=170Hz$
