1. O sursă de oscilații aflată într-un mediu elastic produce unde plane de forma y=50sin(4nt) (mm). Lungimea de undă a undelor longitudinale produse este 1=2 m. Să se afle: a. după cât timp va începe să oscileze un punct situat la distanța x=6 m fată de sursă? b. defazajul între sursă şi punctul de la a. c. distanța dintre două puncte dacă oscilațiile sunt defazate între ele cu t/6

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
