It was possible for small Spanish and Portuguese contingents to claim the Americas in the 1500s because they divided and conquered the indigenous groups residing in the Americas by using intentional tactics that involved advanced armed force and taking advantage of them and their beliefs after gaining their trust and unintentional tactics that included the spread of disease. These tactics were possible to use as the Portuguese and Spaniards had horses and weapons that were advanced compared to the

SOURCES OF ENERGY Energy can neither be created nor destroyed. Energy can only be converted from one form to another. E.g. if we drop a plate from a height‚ the potential energy of the plate gets converted mostly to sound energy when it hits the ground‚ chemical energy in the wax is converted to heat energy & light energy on burning. The total energy during a physical or chemical process remains the same. In the above examples‚ energy in the usable form is dissipated to the surroundings in less
