Answer:
10.13
Explanation:
take note that velocity is distance over time (
) so you do 456(distance)÷45(time)= 10.13
The atom in an excited state has more energy and is less stable than the atom in the ground state.
Hi, thank you for posting your question here at Brainly.
When the object is at equilibrium and the object is just freely hanging from the cord, then the summation of forces along the y direction would just be the tension of the cord and the weight of the object. Since both forces are opposite in direction, at equilibrium, they are equal. Hence, in this case, the tension is also equal to 52 N.
Answer:
14 atoms
Explanation:
Number of atoms in Fe₂(CO₃)₃
An atom is the smallest indivisible particle that takes part in a chemical reaction.
In Fe₂(CO₃)₃; we have:
Elements Number of atoms
Fe 2
C 3
O 3(3) = 9
Total number of atoms = 2 + 3 + 9 = 14 atoms
