Durand Cup is associated with the game of Football.
The Durand Football Tournament or Durand Cup is a football competition in India which was first held in 1888. This competition was named after its founder, Sir Mortimer Durand from Simla.
Which of the following definitions describes a physical hazard?
A) The most commonly thought of hazard in construction. This hazard includes radiation, extreme temperatures, noise, and vibration.
B) These hazards can lead to injuries to the joints or muscles by way of heavy, frequent lifting, repetitive tasks.
C) Can be present in dust, fumes, liquids, solids, mists, vapors, or gases of products used at a site or released during a construction job
D) Microorganisms, such as bacteria, fungus, mold, or viruses that can cause illness.

Answer & ExplanationAnswer: A) The most commonly thought of hazard in construction. This hazard includes radiation, extreme temperatures, noise, and vibration.
Explanation:
A physical hazard is defined as "A factor within the environment that can harm the body without necessarily touching it."
Vibration and noise are examples of physical hazards.
Physical hazards include but aren't limited to electricity, radiation, pressure, noise, heights and vibration amongst many others.
The forces of attraction present in between the molecules or atoms or compounds is termed as intermolecular forces.
The molecule HCl is composed of hydrogen and chlorine atom. There is high difference in electronegativities therefore, it is polar in nature. The H end of HCl is permanently slightly positive charge. The Cl end of HCl has a permanent slight negative charge. the "H" in one molecule is attracted to the "Cl" in a neighbor. The intermolecular force is weak compared to a covalent bond. But this dipole-dipole interaction is one of the stronger intermolecular attractions.
It also has hydrogen bonding and dispersion forces.
Dispersion forces are the weakest forces which are present in between all molecules or atoms. Hydrogen bonds are present in molecules having at least one H-A bond where A is the strong electronegative atom (mainly F, Cl and N).
If the positions of the first and the fifth digits of the number 14278359 are interchanged, similarly the positions of the second and the sixth digits are interchanged and so on, then which of the following will be the second digit from the right end after the rearrangement ?
Given number is 14278359 As given 1st and 5th digits, 2nd & 6th, 3rd & 7th and 4th & 8th digits are to to be interchanged. Therfore, the rearranged number is 83591427 Then, the second digit from the right end is 2.
The systematic name for a chemical is the unique name given to it by the International Union of Pure Applied Chemistry (IUPAC). The IUPAC name can differ from a chemical compound's general name.
PbO is an ionic compound since it consists of a Lead as metal and Oxygen as nonmetal. The systematic name for PbO is Lead (II) oxide. Here we need to put the (II) since lead has more than one combining capacity.
