Two satellites of mass m₁ and m₂ (m₁>m₂) are rowlving mund the earth in consular  archive of r₁ and r₂ (r₁>r₂) respectively. Which of the following statement is true regarding their speeds v₁ and v²

Tunnel vision is caused by

If r represents the radius of the orbit of a satellite of mass m moving around a planet of mass M , the velocity of the satellite is given by

Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite (CuSO₄ ,5H₂O), atacamite cuprite (Cu₂O), copper glance (Cu₂S) and malachite However, 80% of the world copper production comes from the ore of chalcopyrite (CuFeS₂). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. Iron is removed from chalcopyrite as
