Question

2 Drops of water are dripping steadily from a tap (faucet). The diagram shows a measuring cylinder which has collected 120 drops of water. How many drops in total will have been collected when the measuring cylinder reads 10 cm? A) 48 B) 60 C) 120 D) 300

Answer 1

The flow rate of water through a stream depends on its velocity and cross-sectional area. By calculating the flow rate, you can determine the number of drops in total that will be collected.

Step-by-step explanation:

The flow rate of water through a hose can be calculated using the equation:

Flow rate = velocity × cross-sectional area

The cross-sectional area of a circular stream can be calculated using the formula:

Area = π × (radius)²

So in this case, the flow rate can be calculated using the given velocity and diameter of the stream. Once you have the flow rate, you can calculate the number of drops in total that will be collected when the measuring cylinder reads 10 cm.
