The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of one nucleon (1.66·10⁻²⁷ kg).
For example, one carbon atom has mass of 12 amu (unified atomic mass).
The electron has a mass that is approximately 1/1836 that of the proton.
Answer:
<h2>26.67 m/s</h2>
Explanation:
The speed of the car can be found by using the formula
d is the distance
t is the time taken
From the question we have
We have the final answer as
<h3>26.67 m/s</h3>
Hope this helps you
F because it NEVER forms any cations in chemical reactions
5.00 x 1011/s = 5.05500kilohertz
