Two point sources, 5.0 cm apart are operating in phase, with a common frequency of 6.0 Hz, in a ripple tank. A metre stick is placed above the water, parallel to the line joining the sources. The first nodal lines (the ones adjacent to the central axis) cross the metre stick a...

ive been trying to figure this question out for 20 minutes.. if you could help me that would be great. - Dennis, a new medical assistant at Dr. Hernandez's office, notices that Beth has been waiting over an hour to get an allergy shot. Dennis has never given a shot before,...
Two point charges, +3.63 µC and -5.95 µC, are separated by 1.18 m. What is the electric potential midway between them?
A particle has a charge of +1.5 µC and moves from point A to point B, a distance of 0.18 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at...

the total kg would be 85 kg. then multiply by 9.8 to find fg. to lose weight he has to have a downward acceleration ( push downwards on a countertop while standing on the scale).
Write an equation for a cosine function with an amplitude of 2/3 , a period of pi, and a vertical shift of 2 units up.
thank you. this was very helpful.
thank you for responding: i did: (9.0*10^9)cos30((4.0*10^-6)^2)/(0.2^2) using this i got 3.1. so then i need to double it because it's two spheres. right? and sorry about the formula in the question. i confused my self with the "times" and "exponent".
Three spheres, each with a negative chrge of 4.0x10^6C, are fixed at the vertices of an equilateral triangle whose sides are 0.20 m long. Calculate the magnitude and direction of the net electric force on each spehere. i used this: (K)Cos30((4.0*10-6)*2)/(0.2*2) and i get 3.1 ...
