A tank fills at 3 L/min for 4 minutes, then drains at 500 mL/s for 10 seconds. Net litres?
To solve this problem, we need to calculate the total volume of water added to the tank and the total volume of water drained from the tank, and then find the net volume. 1. **Filling the Tank:** - The tank fills at a rate of 3 liters per minute for 4 minutes. - Total volume added = rate × time = \(3 \, \text{L/min} \times 4 \, \text{min} = 12 \, \text{L}\). 2. **Draining the Tank:** - The tank drains at a rate of 500 mL per second for 10 seconds. - First, convert the draining rate to liters per second: \(500 \, \text{mL/s} = 0.5 \, \text{L/s}\). - Total volume drained = rate × time = \(0.5 \, \text{L/s} \times 10 \, \text{s} = 5 \, \text{L}\). 3. **Net Volume:** - Net volume = Volume added - Volume drained = \(12 \, \text{L} - 5 \, \text{L} = 7 \, \text{L}\). Answer: \(7 \, \text{L}\)

To solve this problem, we need to calculate the total volume of water added to the tank and then subtract the volume that is drained. 1. **Filling the Tank:** - The tank fills at a rate of 3 liters per minute for 4 minutes. - Volume added = Rate × Time = 3 L/min × 4 min = 12 liters. 2. **Draining the Tank:** - The tank drains at a rate of 500 milliliters per second for 10 seconds. - First, convert the draining rate to liters per second: 500 mL/s = 0.5 L/s. - Volume drained = Rate × Time = 0.5 L/s × 10 s = 5 liters. 3. **Net Volume:** - Net volume = Volume added - Volume drained = 12 liters - 5 liters = 7 liters. Answer: 7 liters

Unchanged by context: 0% with none, 0% with the strongest supplied source. For a control mode that flat line is the result — it is what licenses reading movement elsewhere in this loop as grounding rather than as a document being present. Nothing survives at the best condition on the cases measured here.
