b) PE fraction = 1/36 = 0.02777
c) 1/2*KX^2 = 1/2*K*(A^2-X^2)
=> X = A/sqrt(2)
Answer:
magnetic force is the force we're to magnet get attracted from the force

Answer:
2 x 10^-8
Explanation:
the formula of wavelength is
the speed divided by frequency
so you have the speed given = 3.0x10^8m/s
and frequency = 1.5×10^16 Hz
so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz
