5. What is the difference between open and closed electric circuit, explain with the help ofdiagrams. |
| Answer» <p>Open circuit: A disconnect in the circuit where there is effectively infinite resistance between the wires/conductor. No current flows.Closed circuit: A loop (aka circuit) is formed and current can flow provided the voltage source has high enough voltage to drive the current, or the loop has low enough resistance to allow the current to flow through it.</p> | |

4. We always calculate average speed and not instant speed. |
| Answer» <p>During a typical trip to school, your car will undergo a series of changes in its speed. If you were to inspect the speedometer readings at regular intervals, you would notice that it changes often. The speedometer of a car reveals information about the instantaneous speed of your car. It shows your speed at a particular instant in time.</p><p>The instantaneous speed of an object is not to be confused with the average speed. Average speed is a measure of the distance traveled in a given period of time; it is sometimes referred to as the distancepertime ratio. Suppose that during your trip to school, you traveled a distance of 5 miles and the trip lasted 0.2 hours (12 minutes). The average speed of your car could be determined as</p><p>On the average, your car was moving with a speed of 25 miles per hour. During your trip, there may have been times that you were stopped and other times that your speedometer was reading 50 miles per hour. Yet, on average, you were moving with a speed of 25 miles per hour.</p> | |

refractive index of diamond is 2.42 what is the meaning of this statement |
| Answer» <p>The refractive index of diamond is 2.42. This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is 1/2.42 times the speed of light in vacuum.</p> <p>The refractive index of diamond is 2.42.
