What happens when a sound wave encounters an obstacle in its path? A sound wave’s wavelength allows it to pass through objects.

Sound waves bend around the corners of obstacles.

Sound waves can easily pass through any object.

A sound wave’s amplitude allows it to move around objects.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
