Consider the following two code segments, which are both intended to determine the longest of the three strings "pea", "pear", a

Nikolay [14]

Answer:

e) Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

Explanation:

if - elseif - else statements work in sequence in which they are written.

In case if() statement is true, else if() and else statements will not get executed.
In case else if() statement is true, conditions in if() and else if() will be checked and else statement will not be executed.
In case if() and else if() both are false, else statement will be executed.

First, let us consider code segment I.

In this, first of all "pea" is checked in if() statement which will look for "pea" only in the String str. So, even if "pearl" or "pear" or "pea" is present in 'str' the result will be true and "pea" will get printed always.

After that there are else if() and else statements which will not get executed because if() statement was already true. As a result else if() and else statements will be skipped.

Now, let us consider code segment II.

In this, "pearl" is checked in if() condition, so it will result in desired output.

Executable code is attached hereby.

Correct option is (e).

Answer:

(i) The rotation speed must stay the same.

(ii) The rotation speed must increase.

(iii) The rotation speed must decrease.

Explanation:

According to Equation

10.10, the angular speed must therefore vary as the laser–lens system moves

radially along the disc. In a typical CD player, the constant speed of the surface at

the point of the laser–lens system is 1.3 m/s.
