The correct answer is circular. Copernicus and other astronomers before him thought that celestial bodies followed a circular orbital path. Copernicus was a Polish astronomer that concluded that the sun is at rest near the center of the universe and the earth is revolving around it annually. This theory is called heliocentric.
The power rating of the engine is 150000 W.
<h3>What is power?</h3>
Power can be defined as the rate at which energy is used or consumed by a body.
To calculate the power of the engine, we use the formula below.
Formula:
- P = FV............. Equation 1
Where:
- P = Power of rating of the engine
- F = Force of the engine
- V = Velocity of the engine.
From the question,
Given:
Substitute these values into equation 1
Hence, The power rating of the engine is 150000 W.

A context is assessed when researching a scientific topic based on the definition, description and analysis to identify research entry points.
<h3>
What is context in scientific topic?</h3>
Scientific research is about weaving together different strands of information, thought, and data to place your results into the context of existing research.
<h3>How is context assessed when researching a scientific topic?</h3>
Context is assessed when researching a scientific topic based on the following;
- is the context well defined?
- is the context well described?
- is the context analyzed sufficiently to identify research entry points?
Thus, context is assessed when researching a scientific topic based on the definition, description and analysis to identify research entry points.

Answer:
The gravitational force is very important to keep the universe functioning. The planets revolve around the Sun because of the force of gravity Galaxies exist also due to gravitational force. ... Stars exist due to gravitational force. It is a binding force that makes the objects round when they are in molten form.
Explanation:
Displacement of a body is always in a straight line in the direction of the final position regardless of the path taken to reach the final position.
Therefore, the displacement of the car can be obtained by joining the car's initial position to the final position and then counting the number of squares covered by the line. Then we multiply the number of squares by the scale and note the direction of the final position from the initial.
that is: 4×1km= 4km North since displacement is a vector.
