Answer:
82.9 mL
Explanation:
1. Volume of silver
2. Volume of gold
3. Total volume of silver and gold
V = 4.766 mL + 2.591 mL = 7.36 mL
4 New reading of water level
V = 75.5 mL + 7.36 mL = 82.9 mL
Answer:
V2 = 6616 L
Explanation:
From the question;
Initial volume = 40L
Initial Pressure, P1 = 159atm
Initial Temperature T1 = 25 + 273 = 298K (Upon converting to Kelvin unit)
Final Volume, V2 = ?
Final Pressure, P2 = 1 atm
Final Temperature T2 = 37 + 273= 310K (Upon converting to Kelvin unit)
These quantities are related by the equation;
P1V1 / T1 = P2V2 / T2
V2 = T2 * P1 * V1 / T1 * P2
V2 = 310 * 159 * 40 / (298 * 1)
V2 = 6616 L
Simply put, MA = Force Out / Force in. That's the way it is usually stated. The force out is normally what you need to move. The force in is what you need to supply to get the force out. Most machines will give you an MA of more than 1. Some (like your arm) will give you less than 1 and others (like this one) will give you exactly one.
This one is frictionless, otherwise it would slip into less than one if it had friction.
