If the atmosphere were 50% more dense, sunlight would be much redder then it is now. As the atmosphere increase in density, more and more of the blue light would be scattered away in all directions, making the light that reaches the ground very red. Think of the color of a deep red sunset, but this would be the color even at noon.
Hope this helps!
Answer:
B. It has increased the chili's potential energy
Explanation:
When there is an increase in the kinetic energy of a substance, the vibrations of atoms and molecules of the substance increases.
This kinetic energy increases the thermal energy of the substance.
So, when there is a decrease in the thermal energy of a substance, the kinetic energy decreases because the random motion of the molecules or atoms becomes feeble.
If the kinetic energy of the substance decreases, the potential energy of the substance increases.
So, if the chili has cooled after 10 minutes, it has increased the potential energy of the substance.
List of metals along with their work function will be provided to you in exams. Here, possible metal is silver(Ag).
I think the correct answer from the choices listed above is the second option. It is amps the unit that tells you about the amount of electrons traveling in the circuit. Amps is coulombs per second and coulombs represents a number of electrons.
Answer:
At point A, the cart has high potential energy. At point b, the cart is pulled down by gravity. At point c, the cart gains its highest kinetic energy. At point d, the cart returns back to the same state but with lower potential energy.
