Explanation

The Compton shift is equal to the Compton wavelength when the scattering angle (θ) is 90°.

Formula:

Δλ = λ' - λ = (h / (mec)) (1 - cosθ)

- When θ = 90°,  

cos(90°) = 0,  

so  

Δλ = h / (mec) → which is the Compton wavelength.

Explanation

The pattern of following series is -

2 + 4 = 6

6 + 5 = 11

11 + 6 = 17

17 + 7 = 24

24 + 8 = 32

Therefore , The sixth term of the sequence is 32 .

Explanation

Explanation

$3\times 4=3\times 4+2=14$ in first example
$5\times 6=5\times 6+3=33$ in second example
$7\times 8=7\times 8+4=60$ in third example
Therefore,
$8\times 9=8\times 9+5=77$ in fourth
Hence, A is correct option.

Explanation

The larger numbers are multiples of the smaller numbers before and after.

... 4 20 5 30 6 42 7 56 ...

4 x 5 = 20

5 x 6 = 30

6 x 7 = 42

Explanation

 If a number is evenly divisible by 2 then it's an even number,

otherwise, it's an odd number.

We can also say when we divide a number by 2 and there is some remainder left,

which is not divisible again by 2,

then it's an odd number.

Explanation

electric charge, basic property of matter carried by some elementary particles

that governs how the particles are affected by an electric or magnetic field.

Electric charge, which can be positive or negative,

occurs in discrete natural units and is neither created nor destroyed.
