Answer:
Explanation:
Energy is defined as the ability to cause changes in matter. The energy of moving matter is called kinetic energy.
Well first you can not go to the 2nd energy level without the first so the first takes up 2 electrons leaving you 5 electrons and the recommended amount is 8 electrons so you would have 5 electrons left
Answer:
C.
Explanation:
The atomic number is derived from the number of protons in the atomic nucleus. The atomic number of bromine is 35, therefore it has 35 protons in its atoms.
Chemical weathering because it used examples of it such as acidic rain and oxidation. Plus they use chemical a few times too.
Solution :
Given :
Mass of the object attached to the spring, m = 2 kg
Velocity of the object as it moves, V = 5 m/s
Amplitude of the object as it swings, A = 2.5 m
We have to find the frequency of the object.
We known,
Therefore, 
f = 0.32 Hz
Therefore the frequency of the object is 0.32 hertz when the amplitude of the 2 kg mass is 2.5 m moving a speed of 5 m/s.
