The step of the scientific method with the information "This paper details my results on how dolphins use sonar to navigate." is: D. Report Results​.

Science can be defined as a branch of intellectual and practical study that systematically observes a body of fact with respect to the structure and behavior of both living and non-living organisms in the natural world through experiments.

Some of the steps (activities or actions) that a scientist performs (carries out) while using a scientific method include the following:

  • Analyze data and draw conclusions.
  • Observation.
  • Experimentation.
  • Report results.

The results of an experiment provide the necessary data and information about the specimen which was used in the course of conducting an experiment.

Hence, a report result would convey these information to the user (reader) of scientific method proposed by a scientist.

In conclusion, a paper which details the results on how dolphins use sonar to navigate is considered a report of the results.

What are the assumptions on which the cosmological principle is based?.
prisoha [69]
Homogeneity and isotropy, On large enough scales, the Universe looks pretty much the same in all directions. The big bang theory is based on two assumptions: the first is centered around Einstein's general theory of relativity, which accurately describes gravity and the interactions of matter; and the second, also known as the cosmological principle, asserts that the universe is homogeneous and isotropic on a large enough scale.

Hope this helps!

Say you want to make a sling by swinging a mass M of 2.3 kg in a horizontal circle of radius 0.034 m, using a string of length 0
ycow [4]

Answer:

T = 764.41 N

Explanation:

In this case the tension of the string is determined by the centripetal force. The formula to calculate the centripetal force is given by:

F_c=m\frac{v^2}{r}  (1)

m: mass object = 2.3 kg

r: radius of the circular orbit = 0.034 m

v: tangential speed of the object

However, it is necessary to calculate the velocity v first. To find v you use the formula for the kinetic energy:

K=\frac{1}{2}mv^2

You have the value of the kinetic energy (13.0 J), then, you replace the values of K and m, and solve for v^2:

v^2=\frac{2K}{m}=\frac{2(13.0J)}{2.3kg}=11.3\frac{m^2}{s^2}

you replace this value of v in the equation (1). Also, you replace the values of r and m:

F_c=(2.3kg)(\frac{11.3m^2/s^2}{0.034})=764.41N

hence, the tension in the string must be T =  Fc = 764.41 N

What is it that makes a magnet different from a piece of iron that is not mangetic?​
Alisiya [41]

Answer:

Under normal conditions, a magnetic material like iron doesn't behave like a magnet because the domains don't have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.
