How do scientist analyze empirical evidence?

1 answer:

4 0

They utilize and apply the scientific method in gathering, interpreting and analyzing empirical evidence.

Empirical evidence, data or knowledge is an obtained set of facts or figures or existing and presenting data that was yielded during the process of experimentation or scientific discovery. These empirical data or evidence is further studied and investigated by the scientist in a formal scientific approach which follows the steps of observation, making a hypothesis, gathering data, interpreting data and evaluating the data. These steps of the scientific approach are vital in the course to explain and discuss the result and evidence obtained during the process.

A uniform 2.50m ladder of mass 7.30kg is leaning against a vertical wall while making an angle of 51.0degree with the floor. A w

Zigmanuir [339]

Answer:

19.95 J

Explanation:

The center of mass of the ladder is initially at a height of:

$h_1=\frac{L}{2}sin\theta$

The center of mass of the ladder ends at a height of:

$h_2= \frac{L}{2}sin90$ =L/2

So, the work done is equal to the change in potential energy which is:

W = PE = $mg(h_2-h_1)$

now $h_2-h_1= 1-sin\theta$

therefore

W = [mgL/2]×[1 - sin(theta)]

W = [(7.30)(9.81)(2.50)/2]×[1-sin(51°)]

solving this we get

W = 19.95 J

What led scientists to the discovery of the strong nuclear force?

kvasek [131]

Answer:

Explanation:

The concept of a new strong nuclear force was introduced. In 1935, the first theory for this new force was developed by the Japanese physicist Hideki Yukawa, who suggested that the nucleons would exchange particles between each other and this mechanism would create the force.
