A. The vibrations of the fields are perpendicular to the direction in which the wave moves.
Answer:
Wavelength = 5.77 * 10^-5 meters.
Explanation:
Given the following data:
Frequency of light = 5.2 *10^12 Hz
We know that the Speed of light = 3.0 * 10^8 m/s
To find the wavelength of light;
Mathematically, wavelength is calculated using this formula;
Substituting into the equation, we have;
Wavelength = 5.77 * 10^-5 meters.
Mass= density x volume
1.3 kg/m^3 x ( 2.5x4x10) m^3
= 130 kg
Answer:
100% efficiency
Explanation:
the machine has _100%_ efficiency.
(fill in the blank)
Q = C.v
v = Q/C
v = 4 × 10^(-10)/250
= 4 × 10^(-10)/2.5 × 10^2
= 1.6 × 10^(-12) volt
