Mandarinka [93]4 years ago
5 0

Answer:

A scientific question  

Explanation:

Comparative research sharpens our capacity for description, as well as stimulating the formulation of concepts, providing criteria for submitting hypotheses and contributing to the discovery of new hypotheses (through inductive) and construction of theories, always through a scientific question.

Comparative research, although it has a large number of cases, allows in any case the possibility of carrying out systematic analyzes which, if used properly, help to confront alternative explanations of a scientific question.

If a machine exerts 12000 J of work with800 N of force the distance it covered was
sergiy2304 [10]

Answer:

<h2>15 m</h2>

Explanation:

The distance covered can be found by using the formula

d =  \frac{w}{f}  \\

f is the force

w is the workdone

From the question we have

a =  \frac{12000}{800}    = \frac{120}{8}  \\

We have the final answer as

<h3>15 m</h3>

The force is the sum of all the forces that act upon an object
11Alexandr11 [23.1K]

Net force or resultant force

Explanation:

The net force or resultant force is the sum of all the forces that acts upon an object. Such forces are able to cause a push or pull on the body.

There are different kinds of forces prevalent on a body at rest and in motion.

A body is acted upon by frictional force and it has its own inertia which makes it resist motion.

Some other types of forces aids motion.

The newton's law of motion gives a very good insight into forces.
