For this problem, let's use the Planck's equation which is written below:
E = hv
where
E is the energy
h is Planck's constant equal to 6.626×10⁻³⁴ J·s
v is frequency
Solving for E,
E = (6.626×10⁻³⁴ J·s)(7.14×10¹⁴ s⁻¹)
<em>E = 4.73×10⁻¹⁹ J</em>
<span>Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). ... Naturally occurring radio waves are emitted by lightning and astronomical objects.</span>
Ok. I finally understood that you need to complete (fill in the blank) the last sentence: The weight of a space probe on the surface of Mars is about ______________
The answer is one third its weight on the surface of Earth.
You can find that by using the formula for the weight:
weight = mass * acceleration due to gravity
So, given that the mass is constant and the acceleration due to gravity is one third, the weight is also one third.
