Answer:</h3>
539.56 Joules
<h3>
Explanation:</h3>
- Efficiency of a machine is the ratio of work output to work input expressed as a percentage.
- Efficiency = (work output/work input) × 100%
- Efficiency of a machine is not 100% because so energy is lost due to friction of the moving parts and also as heat.
In this case;
Efficiency = 94%
Work input = 574 Joules
Therefore, Assuming work output is x
94% = (x/574 J) × 100%
0.94 = (x/574 J)
<h3>x = 539.56 J</h3>
Thus, you get work of 539.56 J from the machine
Asalam a lekum my brother
Answer:
Shorter than(?)
Explanation:
What is it that you're looking for here? Is it just some random fill in the blank question?
My guess is that the horizontal distance has to be shorter than that of the ladder length because if it wasn't then the ladder would be laying down or maybe standing straight up... and you can't really use it normally like that... I'm sorry, where is the Physics in this question exactly?
There are 7 0r 8
Explanation: max atoms you can have are 8 but there is not an 8 in this question so either or
