Setler79 [48]

Answer:

a)15077 W

b)20.2185 horse power

Explanation:

P=F*V

F=ma

a=Vf-VS/t

Vf=28m/s

t=5.2

a=28/5.2

a=5.384 m/s²

F=100kg*5.384m/s²

F=538.4 N

P=F*V

P=538.4N*28m/s

P=15077 W=20.2185 horse power

1W=0.00134 Horse power

Why are chemical processes unable to produce the same amount of energy flowing out of the sun as nuclear fusion?
julsineya [31]

Answer:

Explanation:

One of the major differences between nuclear reactions and chemical reactions is that nuclear reactions involve larger amount of energy than chemical energy. <u>This is because the force between the protons and neutrons in the nucleus of an atom is much higher than the force of attraction between electrons and the positively charged nucleus, hence nuclear reactions involves/requires a larger amount of energy (because it's reactions involve the nucleus) than chemical reactions (because it's reactions involve the electrons)</u>.

Thus, during nuclear fusion, two light nuclei are bombarded against one another to produce a larger/heavier nuclei with the release of large amount of energy (because the forces between the protons and neutrons are much higher) unlike when two atoms/molecules are chemically combined together to form a new molecule with the rearrangement of electrons in the valence shells of the participating molecules.

Anastaziya [24]
<span>Radio waves are the type of wave that most likely transmit cell phones messages. Radio waves can be used to transmit data and information at various frequencies. Gamma rays are high frequency and are dangerous to our health. Ultraviolet rays come from the sun. Infrared waves are ones we experience every day, even though it is invisible to the naked eye. This is the heat we feel from the sun. </span>
