Its okay my friend. you dont need to over stress it.
Answer:
C10H15N is the chemical equation for methamphetamine
Answer:
55 protons, 78 neutrons, 55 electrons
Explanation:
In a neutral Cesium atom we have 55 protons, 78 neutrons and 55 electrons. This can be found on the periodic table of elements.
Protons are the positively charged particles within an atom
Neutrons do not carry any charges.
Electrons are the negatively charged particles.
The amount of these subatomic particles can be obtained from the periodic table of element.
For a neutral atom, the number of protons and electrons are the same.
Since the atomic number is 55, it is also the number of protons in the atom.
Answer:
<h3>The answer is 900 J</h3>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 45 × 10 × 2
We have the final answer as
<h3>900 J</h3>
Hope this helps you
Thompson didnt have a nucleus (since rutherford discovered it)
