The planets have (their) moons. So the answer would be planets.
Answer:
a) 6.9*10^14 Hz
b) 9*10^-12 T
Explanation:
Given that
The wavelength of the wave, λ = 435 nm
Amplitude of the electric field, E(max) = 2.7*10^-3 V/m
a)
The frequency of the wave can be found by using the formula
c = fλ, where c = speed of light
f = c/λ
f = 3*10^8 / 435*10^-9
f = 6.90*10^14 Hz
b)
E(max) = B(max) * c, magnetic field amplitude, B(max) =
B(max) = E(max)/c
B(max) = 2.7*10^-3 / 3*10^8
B(max) = 9*10^-12 T
c)
1T = 1 (V.s/m^2)
B. initiate an action potential.
Action potentials are initiated when a depolarization reaches a threshold potential. This threshold potential varies, but is normally around 55 or 50 millivolts above the resting potential of the cell, which implies that the input current of sodium ions exceeds the output current of potassium ions.
