The given question is incomplete as the options are not provided. The correct options for this questions are as follows-
(1) Good heat conductivity
(2) Good electrical conductivity
(3) Low melting point
(4) High melting point
Thus, the question now is solved below as:
Answer:
Option (3)
Explanation:
Molecular substances are simply defined as those substances that are comprised of more than two atoms and are interlinked with one another. These atoms are linked with each other by the weaker intermolecular forces. This weak bond reflects the low and high melting point of the substance.
These molecular substances differ from the molecular compounds because, in the case of molecular compounds, the atoms are linked with one another by a strong covalent bond.
Thus, the correct answer is option (3).
Answer:
protons
Explanation:
The number of protons in an element is a primary identifier known as its atomic number.
Answer:
Distance, d = 90 meters
Explanation:
Given that,
The speed of sound wave in water, v = 1500 m/s
The time-base setting for the x-axis is 60 ms per division,
Let d is the distance from the ship to the sea bed. We know that the product of speed and time is called distance covered.
d = 90 meters
So, the distance from the ship to the sea bed is 90 meters. Hence, this is the required solution.
