Question

Prove that the points (3, 0), (6, 4) and (-1, 3) are the vertices of a right angled isosceles triangle. By using standard formulae, expand the following:(x - 2y - z)2

Answer 1

The basic thought behind the Davisson and Germer experiment was that the waves reflected from two different atomic layers of a Ni crystal will have a fixed phase difference. After reflection, these waves will interfere either constructively or destructively. Hence producing a diffraction pattern.

Answer 2

Answer:

Given: 3x2−26x+2=0

3x2−6x−6x+2=0,3x(3x−2)−2(3x−2)=0

(3x−2)(3x−2)=0∴3x−2=0 or 3x−2=0

∴3x=2 or 3x=2,x=32

Answer 3

Answer:

Given: 3x2−26x+2=0

3x2−6x−6x+2=0,3x(3x−2)−2(3x−2)=0

(3x−2)(3x−2)=0∴3x−2=0 or 3x−2=0

∴3x=2 or 3x=2,x=32

Answer 4

Answer:

Given: 3x2−26x+2=0

3x2−6x−6x+2=0,3x(3x−2)−2(3x−2)=0

(3x−2)(3x−2)=0∴3x−2=0 or 3x−2=0

∴3x=2 or 3x=2,x=32
