Introduction

Clearly, the Internet has impacted and forever changed higher education in many ways, including the delivery of distance education. Before the arrival of the Internet, many institutions in higher education considered distance education an ancillary program or service for students, used correspondence or remote audio or video technologies, and often included it in continuing education programs. When course delivery using the Internet became an option—creating the new phrase online education —it wasn’t long before enrollments began to rapidly increase and online education became firmly entrenched within higher education. Numerous studies cite tremendous growth in online education, which is currently outpacing that of traditional higher education with the majority of accredited institutions now offering distance learning courses (Allen&Seaman, 2011; Parsad&Lewis, 2008). In fact, more than six million students were enrolled in an online course in 2011, which is almost a third of total students enrolled (Allen&Seaman, 2011). However, along with this tremendous growth were questions about the legitimate quality of online education programs including, What is the definition of quality higher education, and how does it translate to the traditional face-to-face format?

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone
definitely of physics

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
