Answer:
the main cause of decreasingthe efficient of simple machine is the effect of friction so, indoder to increase efficiency of a simple machine we should remove the friction using lubricants, decreasing the overload in machine,replacing sliding friction with rolling friction etc,
we should do thses all to increase efficiency of a simple machine.

One receptor is sensitive to the color green, another to the color blue and a third to the color red.
Hope this helps.
Answer:
Explanation:
in some reactions we see this as a change in the temperature. ... The study of energy changes (particularly heat) in chemical reactions is known as ... When a chemical reaction occurs, bonds in the reactants break, while new bonds form in the product. ... Physical changes can also be classified as exothermic or endothermic.
Answer:
Force = mass × acceleration
Explanation:
The amount of force required to drag the object across the table is the product of the mass of the object and acceleration
