Answer:
29274.93096 m/s




Explanation:
= Distance at perihelion = 
= Distance at aphelion = 
= Velocity at perihelion = 
= Velocity at aphelion
m = Mass of the Earth = 5.98 × 10²⁴ kg
M = Mass of Sun = 
Here, the angular momentum is conserved

Earth's orbital speed at aphelion is 29274.93096 m/s
Kinetic energy is given by

Kinetic energy at perihelion is 
Potential energy is given by

Potential energy at perihelion is 

Kinetic energy at aphelion is 
Potential energy is given by

Potential energy at aphelion is 
Answer:
Explanation:
Units...Nothing is accurate without UNITS. 8.0±0.3 lbs,? Newtons? 3.5±0.2 m²? ft²? cm²? km²? furlong²? fathoms²?
your answer will be 8.0±0.3 / 3.5±0.2 units / units²
<h3><u>Answer;</u></h3>
<em>Electrons </em>
<h3><u>Explanation;</u></h3>
- <em><u>Thomson contributed to the model of an atom by discovery of </u></em><em><u>electrons </u></em><em><u>and thus proving the existence of sub-atomic particles in an atom. </u></em>
- <u><em>Thomson used cathode ray tube, and demonstrated that cathode rays were negatively charged.</em></u> According to his model normally known as the plum pudding in which he stated that an atom is composed of electrons as subatomic particles that are surrounded by positive charges to balance the electrons.
Light intensity is the "amount of light given off a light source." Also, is the measure the wavelength of the amount of light given off by a light source.
Hope this helps.
