Which of the following objects will exert the greatest gravitational force on a box, if the distance between them stays the same
Mumz [18]

Answer:

D). 8 kg mass

Explanation:

Acceleration of Falling Objects

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system. ... The stronger the pull of gravity on an object, the greater its weight.

Use the picture to tell if it is accurate , precise , or both?
Anton [14]

Answer:

Accurate - Yes

Precise - Yes

Explanation:

Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.

Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.

Note that, a measurement may be accurate but not precise or be precise but not accurate.

In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.

Therefore, the measurements are both precise and accurate.

According to the opponent color theory, the perception of color is based on the output of _______ cones, each of them an opponen
antoniya [11.8K]
<h2>1. Three cones</h2><h2>2. Two colors</h2>

Explanation:

  • The opponent process theroy of color vision recommends that our capacity to perceive color is constrained by three receptor complexes with contradicting or opposing activities.
  • These three receptor complexes are as follows:
  • Dark white complex.
  • Blue-yellow complex.
  • Red-green complex.
  • You don't see greenish-red because according to the opponent process theory, the opponent cells can just identify each of these colors at a time.
