<h3>
Answer:</h3>
60 %
<h3>
Explanation:</h3>
We are given ;
- Work input as 5000 Joules
- Work output as 3000 Joules
We are required to calculate the efficiency of the machine;
What is efficiency?
- Efficiency is the ratio of work output to inputs expressed as a percentage.
Efficiency = (work output ÷ work input) × 100
= (3000 J ÷ 5000 J) × 100
= 60 %
Thus, the efficiency of the machine is 60%.
- The substance that made up of a particular mixture can be regarded as Solute and solvent
- A mixture can be regarded as material which is made up of more than one different Chemical substance or substances , whereby they are not chemically combined.
- Substance could be any matter such as <em>salt, rice, and or compounds</em>
- A mixture can be regarded as physical combination involving two or more substances whereby each entities identities are retained, then mixed in the form such as ;
- <em>solutions</em>
- <em> suspensions </em>
- <em> colloids</em>.
- A mixture could be in this form <em>(Solute + solvent = solution)</em>
Therefore, the substance that made up of a particular mixture can be regarded as <em>Solute and solvent</em>
