Molly used a ramp to load boxes into a truck. her input work was 5,000 j and
the output work was 3,000 j. what was the mechanical efficiency of the
ramp?
answer quick

60 %

We are given ;

We are required to calculate the efficiency of the machine;

What is efficiency?

Efficiency = (work output ÷ work input) × 100

                = (3000 J ÷ 5000 J) × 100

                = 60 %

Thus, the efficiency of the machine is 60%.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
