I really really really need help with this one question, if answered correctly or attempted will get brainliest :) For the circuit shown with a 12.0 V battery, what are the currents through each resistor and the voltage drops across each resistor?

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c

How much heat is needed to raise the temperature of 5g of water by 16°c?

If the wavelength is tripled, while the speed of the wave is held constant, what happens to the frequency?
