Answer:

Only options a reflects the instances with valid experiment or conclusion.

Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.

Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).

Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.

Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.

Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.

If a rock has a volume of 2cm3 and a mass of 12g what is its density
cestrela7 [59]

Answer:

If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.

Explanation:

Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.

If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:

ρ = m/V

Therefore, according to the mass and volume of the rock

ρ = 12 grs / 2 cm³

<em>ρ = 6 grs/cm³ </em>

Being the density of the rock equal to 6 gr/cm³.
