<span>When we see a solid color that is red, blue, or black let's say, it is said to have a high saturation of color. A color that is almost gray has very little or very saturation. Of course, the amount of gray can vary greatly but for the most part a color that is almost gray has little or no saturation at all.</span>
Answer:
Explanation:
The distance of Earth from the Sun is and of Mars from the Sun is . Let assume that both planets have circular orbits. The centripetal accelaration can be found by using the following expression:
Since planet has translation at constant speed, this formula is applied to compute corresponding speeds:
Earth:
Mars:
Now, centripetal accelarations can be found:
Earth:
Mars:
The ratio of Earth's centripetal acceleration to Mars's centripetal acceleration is:
Answer:
Explanation:
The equation of electric field is
E = 375 Sin(5.97 x 10^15 t + 1.99 x 10^7 x)
Compare with the standard equation
E = Eo Sin(ωt + kx)
(b) Amplitude of electric field, Eo = 375 V/m
Amplitude of magnetic field, Bo = Eo / c = 375 / (3 x 10^8)
Bo = 125 x 10^-8 Tesla
Bo = 1.25 x 10^-6 Tesla
(c) ω = 5.97 x 10^15 rad
2 x 3.14 x f = 5.97 x 10^15
f = 0.95 x 10^15 Hz
f = 9.5 x 10^14 Hz
