Answer 1

Answer:

★The resultant of forces along AB and

CD : p - 3p = - 2p = P

This is along CD direction

★The resultant of forces along BC and

DA : 2p - 4p = - 2p = Q

This is along DA direction.

Since P and Q are equal in magnitude and are perpendicular to each other , it is easy to find the resultant.

• The resultant of forces P and Q will be √2 2 p

• The direction is 45 deg. to either DA or BA.

Answer 2

Answer✔️✏️

Metals are separated by nonmetals on a periodic table through a zigzag line starting from carbon, till radon. The elements between the two are phosphorus, selenium and iodine. These elements and elements right to them in the periodic table are nonmetals.
