Question

Let A be a two-dimensional array declared as follows: A: array[1..110][1..125] of integer; Assuming that each integer takes one memory location, the array is stored in row-major order and the first element of the array is stored at the location. Find out the address of the address of the element A[i][j].

Answer 1

Answer:

Step-by-step explanation:

For standing waves, the spearation between consecutive nodes or antinodes.

`d=n(lambda)/(2)" " ....(i)`

`n=1,2....`

For next node,

`d'=(n+1)(lambda)/(2) " " ....(ii)`

`d'-d=(lambda)/(2)rArr-3=(lambda)/(2)rArrlambda=1 Å`

de-Broglie wevelength `lambda=(h)/(sqrt(2mK))`

`rArrK=(h^(2))/(2mlambda^(2))=((6.6xx10^(-34))^(2))/(2(9.1xx10^(-31))xx(10^(-10))^(2))=2.415xx10^(-17) J`

`=(2.415xx10^(-17))/(1.6xx10^(-19))=150 eV`

For minimum value of d, n=1

`:. " " d=n(lambda)/(2)=(lambda)/(2)=(1)/(2)=0.5Å`
