Answer:
0.71121 km/s
Explanation:
= Velocity of planet initially = 54 km/s
= Distance from star = 0.54 AU
= Final velocity of planet
= Final distance from star = 41 AU
As the angular momentum of the system is conserved
When the exoplanet is at its farthest distance from the star the speed is 0.71121 km/s.
Answer:
The statement that best describes nuclear fusion is;
Nuclei combine to form a heavier nucleus, releasing energy
Explanation:
In nuclear fusion, we have the reaction of the nuclei of two or more atoms coming together (combining) to form heavier elements and subatomic particles such as protons and neutrons accompanied by the release or absorption in energy depending on the difference between the mass of the reactants and the products
Some nuclear fusion reaction require an input of energy and such reactions are therefore not spontaneous
The best option is nuclei (two or more nuclei) combine to form a heavier nucleus, releasing energy.
F = MA
30,000 kg * 1.5 m/s^2 = 45,000 N
Refraction is simply the bending of light when it moves from one material into another. If light is beamed at 90° to a surface, no bending happens. But if you shine the light at an angle it will bend one way or another.
Diffraction is a process in which a beam of light travels through a gap or around a barrier, and spreads out as a result.
<span> Dispersion is the property that the speed of light in a transparent material is different for different wavelengths. Thus the index of refraction is likewise different.</span>
Answer:
780 m to travel north
Explanation:
6 m over = 750
53 degree so it will take about 2 min to reach the destination
