The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of 0.8. An ac voltage V_WX1 = 100 V is applied across WX to get an open circuit voltage across YZ. Next, an ac voltage V_YZ2 = 100 V is applied across YZ to get an open circuit voltage V_WX2 across WX. Then, are respectively

125/100 and 80/100

100/100 and 80/100

100/100 and 100/100

80/100 and 80/100

The height of a tree is defined as the number of edges on the longest path in the tree. The function shown in the pseudocode below is invoked as height (root) to compute the height of a binary tree rooted at the tree pointer root.
int height (treeptr n)

The appropriate expressions for the two boxes B1 and B2 are

B1: (1 + height (n

right))
B2: (1 - max (h1, h2))

B1: (height (n

right))
B2: (1 - max (h1, h2))

B1: height (n

right)
B2: max (h1, h2)

B1: (1 + height (n

right))
B2: max (h1, h2)

Yes, 1 needs to be added, But Option A is anyways wrong since it says 1 - max(h1, h2). Why SUBSTRACTION IN OPTION 1?????

Let G be a weighted graph with edge weights greater than one and G` be the graph constructed by squaring the weights of edges in G. Let T and T` be the minimum spanning trees of G and G` respectively, with total weights t and t`. Which of the following statements is TRUE?

T` = T with total weight t` = t²

T` = T with total weight t` < t²

T but total weight t` = t²

None of these

Year can be normal or leap. So the answer should be 5/28

Probability of success is S = 1/4 probability of failure is Q= 3/4 from binomial theorem with n=2 r=0 we have ncr(P)^r(Q)^(n-r)= 2c0(1/4)^0(3/4)^2 = 9/16 ans
