The answer is:

B. false

Here's why:

The Ptolemaic model is not accurate and this is because the model is geocentric. This means that this model was developed with the assumption that the Earth was the center of the universe and the sun and the planets revolved around it. Science has already proven that this is not true.

This model was developed by Claudius Ptolemy.

How does the resultant displacement change as the angle between two vectors increases from 90° to 120°?

user100 [1]

The resultant displacement between the two vectors will increase.

The resultant of the two vectors is given by parallelogram law of vectors.

The parallelogram law of vector addition states that if two vectors are represented in magnitude and direction by the adjacent sides of a parallelogram, the diagonal of the parallelogram drawn from the point of intersection of the vectors represents the resultant vector in magnitude and direction.

The resultant of these vectors, say vector A, and B, is given as;

$R^2 = a^2 + b^2 -2ab.Cos (\theta )$

When;

θ = 90°

$R^2 = a^2 + b^2$

When;

θ = 120°

$R^2 = a^2 + b^2 + ab$

Thus, the resultant displacement between the two vectors will increase.

A 100-meter sprint is a race using only the straight side of a racetrack. A 400-meter sprint is a race that makes one complete l

Shalnov [3]

Speed uses distance and velocity uses displacement in its calculation.

For 100 m race, distance = displacement. Hence speed = velocity

For 400m race, distance ≠ displacement. distance = 400m whereas displacement = 0m. Hence speed ≠ velocity

Describe the Earth's rotation around the Sun

satela [25.4K]

The Earth's orbit is the path through which the Earth travels around the sun. A complete orbit occurs every 365.256 days, where the Earth is traveling at 940 million km during a single orbit.
