A dipole is composed of a pair of point charges ±, separated by a distance and aligned parallel with the - axis, as shown in the figure. Find the expression for the potential on the - axis at point F located at =8.70×10−8 cm, where ≫. Then, evaluate the potential for a dipole moment of =6.21×10−30 C·m. The Coulomb force constant is =1/(40)=8.99×109 N·m2/C2.

Which sentences describe disadvantages of burning fossil fuels instead of using hydrogen fuel cells? burning fossil fuels contributes to climate change. burning fossil fuels takes place inside expensive fuel cells. fossil fuels aren't widely available, but pure hydrogen is. fossil fuels are nonrenewable.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

What is the final velocity of the initial velocity of 25 and -50?
