Given:-
- Time taken by the particle (t) = 6 s
- Average speed (v) = 40 m/s
To Find: Distance (s) travelled by the particle.
We know,
s = vt
where,
- s = Distance travelled,
- v = Speed &
- t = Time taken.
Putting the values,
s = (40 m/s)(6 s)
→ s = 240 m ...(Ans.)

Answer:
Option B
Explanation:
The correct answer is Option B.
Before Moseley's discovery in 1913, In Mendeleev's periodic table the elements rearranged with increasing atomic mass.
Mendeleev was not able to locate hydrogen atom and late isotopes found violate Mendeleev table. The biggest drawback was that the atomic mass was not regular when moving one element to another.
But Moseley's arranged element in the periodic table with increasing atomic number.
