Answer:
Without taking body measurements, the fabric material can run out of supply if the tailor uses it too much. And more material is required to fix small dresses or suits. So when body measurements are taken accurately, the tailor will know the exact amount of material to be used.
Explanation:
La magnitud fundamental es aquella que se define por si misma y es independiente mientras que la magnitud derivada es aquella que se obtiene mediante expresiones a partir de las magnitudes fundamentales. :)
Answer:
The ability of the molecule to pack more tightly increases the melting point.
Explanation:
In hydrocarbons of same molecular formula, melting point is determined by:
- weak intermolecular forces
- Molecular symmetry
Higher the intermolecular forces and molecular symmetry, higher will be the melting point.
Intermolecular forces in hydrocarbons decreases with branching. Moreover, branching interfere the tight packing of the molecule in the crystal. Therefore, branched hydrocarbons tend to have lower melting point.
However, in highly branched hydrocarbons molecular symmetry increases which results in tight packing of the molecule in the crystal.
So, highly tight packed molecules tend to have high melting point.
As (CH3)2CHC(CH3)3 is highly branched and has high molecular symmetry, therefore, its melting point is highest among given.
So, among the given, option c is correct.
The Solar System may be divided by its components into three major regions: the inner system, the near outer system, and the far outer system. The near outer system might also be referred to as the middle system.
Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.
Goodluck my friend!!

Explanation:
Here in this question question, we are concerned with writing the Lewis structure for the given molecule.
The Lewis structure is simply using dots to represent electrons which are not involved in the bonding.
That is, we shall be using dots to represent the non-bonding pairs of electrons around the atoms which are central.
