The closer the particles, the more will be the propogation of sound waves. Room contains air molecules which are far away from each other. So it takes much time for one molecule of air to disturb the other one. But in case of solids, as particles are much closer(compared to fluids), disturbance generated by one molecule is quickly transmitted to the next molecule

Answer:

Total time spend = 48.18 hours (Approx)

Explanation:

Given:

Total distance = 5,300 km

Average speed = 110 km / h

Find:

Total time spend

Computation:

Time = Distance / speed

Total time spend = Total distance / Average speed

Total time spend = 5,300 / 110

Total time spend = 48.18 hours (Approx)

Suppose Galileo and his assistant were 1 km apart when Galileo uncovered his lantern to try to measure the speed of light. How l
Black_prince [1.1K]
The speed of light is approximately 3.00 x 10^8 m/s. Then the next step is to convert m/s into km/s.To determine the time, the distance must be divided with velocity. It will take the light signal 3.3*10^-6 seconds to reach his assistant.

What is semiconductor device that produces electric current through the effect for which its named?
nlexa [21]

The semiconductor device that produces electric current through the effect is termed as transistor.

To find the answer, we have to know more transistor.

<h3>What is transistor?</h3>
  • Transistors come in two different types: field-effect transistors and bipolar junction transistors.
  • The formation of two p-n junctions in various configurations, such as n-p-n or p-n-p, results in bipolar junction transistors.
  • The emitter, collector, and base, or middle region, are the three areas that form in a transistor.
  • The conductivity of the field-effect transistor, which is based on the conductivity principle, can be changed by an electric field.

Thus, we can conclude that, the semiconductor device that produces electric current through the effect is termed as transistor.
