Textbook Question
Chapter 19, Problem 1RQ
Review Question 19.1 What condition(s) is/are needed for electric charge to continuously travel from one place to another?
Expert Solution & Answer
To determine
The conditions required for electric charges to travel from one place to another place.
Answer to Problem 1RQ
Solution:
There must be a potential difference in the circuit, and the circuit must form a closed loop and be made from a conducting material.
Explanation of Solution
Introduction:
Electric charges are physical quantities that are found freely moving in conductors. In conductors, there are loosely held electrons, and so it is easy for them to flow when some energy is added to the conductor.
Explanation:
When the potential difference is applied to the closed loop, the electric charges start to flow in the closed loop and the flow continues until the loop is broken, or the potential difference is removed from the conductor.
Conclusion:
The closed loop of conductor and a potential difference are the perquisites for charge to flow from one place to another.

Consider a image that is located 30 cm in front of a lens. It forms an upright image 7.5 cm from the lens. Theillumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observedat 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,inverted image is now 10 cm on the incident side of the lens.What is the index of refraction of the lens?
2. In class, we discussed several different flow scenarios for which we can make enough
assumptions to simplify the Navier-Stokes equations enough to solve them and obtain
an exact solution. Consulting the cylindrical form of the Navier-Stokes equations copied
below, please answer the following questions.
