Scientist Engineer Interview Questions and Answers

Characteristic impedance is the ratio of voltage to current in a transmission line and represents the resistance to the flow of electrical energy.

• It is a measure of the resistance to the flow of electrical energy in a transmission line

• It is the ratio of voltage to current in a transmission line

• It is a function of the geometry and materials of the transmission line

• It determines the maximum power that can be transmitted through a transmission line without distortion

• It is import...read more

Challenges in deep space communication include distance, signal interference, and equipment failure.

• Distance: Signals weaken over long distances and can take minutes or even hours to reach their destination.

• Signal interference: Cosmic radiation and other sources of interference can disrupt or distort signals.

• Equipment failure: Malfunctions in communication equipment can occur due to the harsh conditions of space.

• Limited bandwidth: The amount of data that can be transmitted is...read more

Strength of materials is a branch of engineering that deals with the behavior of solid objects subject to stresses and strains.

• Strength of materials involves studying how materials deform and break under various types of loads.

• It is important in designing structures and machines to ensure they can withstand the forces they will be subjected to.

• Examples include calculating the maximum load a bridge can support or determining the thickness of a metal beam needed for a specific ...read more
