Answer:
The final velocity is -49.05 meters per second.
Explanation:
Let's use an equation of constant acceleration:
Where a is the acceleration and g is the acceleration caused by gravity.
Since the object is being dropped from rest, .
We're looking for the speed after 5 seconds, so .
So the final velocity is -49.05 meters per second.
Protons, electrons, and neutrons have electrical charges. Protons are positive. Electrons are negative and neutrons are neutral (no charge).<span />
E = 0.25 = m*g*h
<span>h = 0.25/(m*g) = 0.25/(0.125*10) = 0.25/1.25 = 1/5 = 0.20 m
I hope this helps you have a great day and im sorry it took so long to get an answer</span>

The different types of radiation in electromagnetic spectrum are compared by the amount of energy found in the photons.
Radio waves have photons with low energies, microwave photons have a little more energy than radio-waves. Infrared photons still have more energy, then comes visible, ultraviolet, x-rays and the most energetic of all, gamma rays.
The energy associated with electromagnetic radiation is proportional to frequency and inversely proportional to wavelength. So, electromagnetic waves with shorter wavelengths have more energy.
On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light. On the other end of the spectrum are gamma rays with wavelengths billions of times smaller than those of visible light.
