If measuring experimental results, what can you predict about the work output of a 1200 watt hair dryer? the work output of the hairdryer will be less than the work input the work output of the hairdryer will be equal to the work input the work output of the hairdryer will be greater than the work input the work output of the hairdryer cannot be predicted in the real world

The work output of a 1200 wwtt hair dryer will be less than the work input. Work input is equal to Force times distance. To solve the mechanical efficiency it will be work output divided by work input times 100%. It is a simple machine so the work output is less than the work input which means the work. In addition, work output is overcomes friction causing it to lose its energy but there is still work done . Work input is equal to the work output plus the work done to overcome the friction.

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?

Idon't know hope someone you
