Q. How long will it take you to write code for the Fibonacci series?

Ans.

The time taken to write code for Fibonacci series depends on the programming language and the approach used.

  • The recursive approach is simple but can be slow for large inputs.

  • The iterative approach is more efficient and faster.

  • Dynamic programming can be used to optimize the recursive approach.

  • The time complexity of the iterative approach is O(n), while the recursive approach is exponential.

  • Using memoization can improve the performance of the recursive approach.

Q. How does a wind turbine generate power?

Ans.

Wind turbines generate power through the conversion of wind energy into electrical energy.

  • Wind turbines have large blades that capture the kinetic energy of the wind.

  • The wind turns the blades, which are connected to a rotor.

  • The rotor spins a generator, which produces electricity.

  • The electricity generated is then transmitted through power lines for use.

  • Wind turbines can generate power even at low wind speeds, but their efficiency increases with higher wind speeds.

Q. How many outer walls need coating?

Ans.

The number of coating outer side walls depends on the specific engineering project and its requirements.

  • The number of coating outer side walls varies depending on the type of structure being built.

  • For example, a building may have one or multiple coating layers on its outer walls.

  • The number of coating layers may also depend on the climate and environmental factors of the location.

  • The engineer must determine the appropriate number of coating layers based on the project's specif...read more
