The fixed the the lever pivots around is called the fulcrum
FULL ANSWER
Neutrons and protons make up a nucleus and they are in the middle of an atom. Electrons surround the nucleus. Opposite charges attract each other. Because of this, protons do not attract other protons and electrons do not attract other electrons. Instead, protons attract electrons and electrons attract protons. When someone looks at the elements on the periodic table, they can see how many protons are present by looking at the atomic number. Since atoms have to have an equal amount of each, if an element contains 36 protons, it also has 36 electrons.
The time taken for the bus to travel 95.1 m is 2.8 s
<h3>How to determine the final velocity</h3>
- Initial velocity (u) = 26.8 m/s
- Acceleration (a) = 4.73 m/s²
- distance (s) = 95.1 m
- Final velocity (v) = ?
v² = u² + 2as
v² = 26.8² + (2 × 4.73 × 95.1)
v² = 1617.886
Take the square root of both sides
v² = √1617.886
v = 40.2 m/s
<h3>How to determine the time</h3>
- Initial velocity (u) = 26.8 m/s
- Acceleration (a) = 4.73 m/s²
- Final velocity (v) = 40.2 m/s
- Time (t) = ?
v = u + at
40.2 = 26.8 + (4.73 × t)
Collect like terms
4.73 × t = 40.2 - 26.8
4.73 × t = 13.4
Divide both side by 4.73
t = 13.4 / 4.73
t = 2.8 s
