If you are operating a power driven vessel that is underway in condition of restricted visibility, you are expected to do the following: sound prolonged blasts every two minutes. If the vessel is underway but is not moving, it is expected to sound two prolonged blast every two minutes. When one hears any of the signal above, one is expected to reduce speed to the minimum that is needed to keep on course.
Answer:
The speed of the car is 75 km per hour
Explanation:
Speed is distance over time so 150 km divided by 2 hours is 75km per hour.

Answer:</h3>
Homogeneous mixture with components of different boiling points
<h3>
Explanation:</h3>
- Distillation is a method of separating miscible mixtures which contain components that have different boiling points.
- The mixture is heated and the component with the low boiling point evaporates first. It is then condensed in the condenser and the distillate collected using a clean beaker.
- For example, a miscible solution of ethanol and water can be separated using distillation.
- Ethanol and water have different boiling points of 78°C and 100°C respectively. Ethanol is distilled out first because it has a low boiling point compared to water.
