Answer:
The acceleration is 10 m/s²
Explanation:
The question seeks to show the relationship between force, mass and acceleration. Hence, the formula to be used here is that of force which is shown below
F = ma
where F is the force (800 N)
m is the mass (80 kg)
a is the acceleration (unknown)
From the formula above (Force = mass multiplied by acceleration)
800 N = 80 kg × a
a = 800 ÷ 80
a = 10 m/s²
he number following the symbol represents a change in neutrons and mass numbers.
<u>Explanation:</u>
The chemical symbol is the abbreviation used to identify the element or atom of the element. The isotope symbols of specific element is recorded by placing a mass number as superscript in left to the element's symbol. The protons count (also referred as atomic number) as subscript precedes the symbol. For example, magnesium is the three isotopes mixture with 12 as atomic number and a mass numbers as 24, 25 and 26.
These isotopes can identify as . These isotope symbols are read as "element, mass number" and can be symbolized by this reading. For example, is read as "Magnesium 24" and so on. All magnesium atoms contain 12 protons in the nucleus. So, it indicates the neutron variation and mass numbers.
I did 25m/ 2.5s which is 10 m/s. not exactly sure tho
Answer A is correct - m1l
