Conduction is the transfer of energy by collusion between the atoms and molecules in a material.
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:
Explanation:
The change in force = 9.81(1.95 - 0.300) = 16.2 N
The change in length is 0.750 - 0.200 = 0.550 m
K = ΔF/Δx = 16.2/0.550 = 29.4 N/m
Weight of the object is given as
so weight of the object will be maximum where gravity(g) will be maximum
so here out of all given four the gravity "g" will be maximum at the surface of SUN as we know that sun will be of maximum mass out of all four planets
as we know that
so correct answer will be
3. SUN
