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.
Answer:
602.27 kg
Explanation:
The computation of the largest mass of cargo the balloon can lift is shown below:-
Volume of helium inside the ballon= (4 ÷ 3) × π × r^3
= (4 ÷ 3) × 3.14 × 6.953
= 1406.19 m3
Mass the balloon can carry = volume × (density of air-density of helium)
= 1406.19 × (1.29-0.179)
= 1562.27 kg
Mass of cargo it can carry = Mass it can carry - Mass of structure
= 1562.27 - 960
= 602.27 kg
Answer:
c
Explanation:
Mineral water, water, and salt water are all liquid solutions, while oxygen is a gas. Gases are less dense than liquids.
For every force in nature that there is an equal and opposite reaction
That type of energy is called "energy transformation".<span />
