Concept explainers

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…

Textbook Question

Chapter 21, Problem 70GP

A proton is released from rest at the positive plate of a parallel-plate capacitor. It crosses the capacitor and reaches the negative plate with a speed of 50,000 m/s. What will be the proton’s final speed if the experiment is repeated with double the amount of charge on each capacitor plate?

After the countdown at the beginning of a Mario Kart race, Bowser slams on the gas, taking off from rest. Bowser get up to a full speed of 25.5 m/s due to an acceleration of 10.4 m/s2. A)How much time does it take to reach full speed? B) How far does Bowser travel while accelerating?

The drawing in the image attached shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Side 1 has an area of 1.90 m^2, Side 2 has an area of 3.90 m^2, the electric field in magnitude is around 215 N/C. Please find the electric flux magnitude through side 1 and 2 combined if the angle (theta) made between the electric field with side 2 is 30.0 degrees. I believe side 1 is 60 degrees but could be wrong. Thank you.
