Answer:
The wave is traveling in the y axis direction
Explanation:
Because the wave will always travel in a direction 90° to the magnetic and electric components
Answer:
The potential energy decreases
Explanation:
- When a proton moves in the direction of the electric field, the force on the proton (f=qE) will be in the direction of the field.
- The proton will accelerate and the KINETIC energy will increase.
- The potential energy decreases.
Answer:
μ = 0.31
Explanation:
The friction force must provide the needed centripetal force
mω²R = μmg
μ = ω²R/g = (2π/1.8)²(0.25) / 9.8 = 0.31
