In scientific investigations, how does empirical evidence help scientists devise hypotheses?
nika2105 [10]

Answer:

Explanation:

An empirical evidence illustrates facts that are drawn from experimentation and observations. These are usually drawn from the way we see and percieve our environment using our senses.

A hypothesis is best and simply defined as a scientific guess. It is often a direct product of empirical studies of a particular problem. Most times when scientists gather facts and principles have been formulated, they try to explain their observation. This explanation is the hypothesis. The satement of the hypothesis is usually tentantive. Sometimes, we can have several hypothesis for a common source of empirical evidence.

You return from open sea. You see a green lighted buoy with a number 3. What should you do?
Crazy boy [7]

The markers and colored buoys serve as the "traffic signals" that direct boats to safety. Lateral navigation markers and non-lateral markers of the US Aid to navigation System must be learned for all operators. A green-lighted buoy marks the border/edge of the channel on the operators' port (left side) as the boat enters from open sea. The odd number 3 signals your direction and distance in returning from open sea( as the number increases).
