Answer:

22.5 s is the correct answer to the given question .

Explanation:

Given that

d=7.5km=7.5\times 10^3 m

For light:

We know that speed of light c

c=3\times 10^8 m/s

We know that

Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms

For thunder :

Speed of sound ,v=332 m/s

Time\  taken\  by\  sound \\t\’=\dfrac{7500}{332}=22.59 s

Therefore the difference between time is given as follows

\Delta t= t' - \ t=22.59-2.5\times 10^{-5}=22.59 s

22.5 is the answer

Which line in the following program will cause a compiler error?
Viktor [21]

Answer:

The answer is "Option A".

Explanation:  

  • In the given C++ Language program on line 8 compile-time error will occur, because in the code the conditional statement is used. In if block, we check two conditions together, which is the number variable value is greater than equal to 0 and check less than equal to 100.  
  • In this condition statement, a AND operator is used that execute when both condition is true, but in the last condition, we do not define a variable name that, checks value. That's why the program will give an error on line 8.
