Answer:
When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.

<h2>Answer</h2>
Radius is 421 m.
<u>Explanation </u>
A car with a mass of 1,500 kg requires a centripetal force of 640 N to safely follow a circular curve in the road at 13.4 m/s. Therefore, for radius we use formula which is Fc = mv ^ 2 / r,
As mass = m = 1500kg,
Centripetal force = Fc = 640N,
Velocity = v = 13.4 m / s
By putting values, Fc = mv ^ 2 / r,
r = mv ^ 2 / Fc,
=> r = ( 1500kg ) . ( 13.4 m / s) ^ 2 / 640,
=> r = ( 1500kg ) . ( 179.56 ) / 640,
r = 269340 / 640,
=> r = 420.84 m.
Radius is 421 m.
Answer:
Earth’s Moon:
It has no atmosphere due to weak gravity. Venus: It is too hot for liquid water.
Europa:
Is too cold for liquid water Mars: Scientists believe it used have flowing water Europe is a small moon of the planet Jupiter and according to studies, it is confirmed that the moon is too cold to have liquid water.
Venus: Venus is generally known as an extremely hold planet where liquid water would immediately turn into gas.
Mars:
is popularly identified with aliens since several theories talk about a prehistoric alien race that lived on it’s surface.
False because the physics is like a science and it’s like a math
Answer:
Food accounts for 10-30% of a household's carbon footprint, typically a higher portion in lower-income households. Production accounts for 68% of food emissions, while transportation accounts for 5%.
