The atom in an excited state has more energy and is less stable than the atom in the ground state.
The outer planets have a high gravity due to their large size
Answer:
the force required to accelerate a 1,100kg car is 550N
Answer:
972 J
Explanation:
At the bottom, all the gravitational potential energy was converted into kinetic energy. If you calculate the GPE, its value will be the same that the KE at the bottom. The GPE can be calculated this way:
GPE = mass×gravity×heigth
GPE = 2.2×9.8×45.08 ≈ 972
Answer:
The diagram assigned B
explanation:
Check the direction of the two vectors, their resultant must be in the same direction.
