Explanation:
c. if the vector is oriented at 0° from the X -axis.
Answer:
There are a number of models as explained below.
Explanation:
- Depending on the position of the earth in the orbit, stars will be in different positions relative to the distant stars.
This model can be explained by the parallax effect. An object is viewed differently by the left and the right eye.
Reference can be made to the geocentric and heliocentric arguments. The first view argues that heavens are composed of 55 concentric spheres.
On the other hand, the heliocentric system, proposed by Copernicus, suggested that the Sun, not the earth, was the center of the solar system.
<h3>
Answer:</h3>
60 m
<h3>
Explanation:</h3>
<u>Concept Used:</u>
We know that the area under a velocity-time graph represents the Displacement of the body
<u>Displacement in the Last 6 seconds:</u>
To find the Displacement in the last 6 seconds, we will find the area under the graph between x = 4 and x = 10
We can see that the shape formed is a rectangle also shown in the given graph. So, the area of the rectangle is the Displacement of the car in the last 6 seconds
<u>Area of the Rectangle:</u>
From the graph, we know that the rectangle is 10 (m/s) tall and 6 (s) wide
Area of Rectangle= length*Breadth
replacing the values
Area = 10 (m/s) * 6 (s)
Area = 60 m
Hence, the car travelled 60 m in the last 6 seconds of the graph
The velocity is 0 m/s, as when it reaches the top, the object has no velocity for a small period of time as it then switched to a negative velocity when coming down
