Explanation:
Below is an attachment containing the solution.
<span>Because of our perception of the universe from inside the universe, we are unable to see how and towards what the universe is expanding. Also, our understanding of it is further complicated because we are moving as part of the expansion, thus distorting our perception of it.</span>
Answer: Carbon
Explanation:
The opening graph in the video shows the measured relative abundances of elements in the galaxy. What is the 4th most abundant element? Carbon has the fourth highest dot on the graph, and therefore is the fourth most abundant element.
Car is driven first 2.0 hour at the velocity 40 km/h.
We know,
Distance covered = Velocity * time.
Therefore, distance covered by car in first two hours = 40 * 2.0 = 80 km.
Car is driven second 2.0 hour at the velocity 60 km/h.
Therefore, distance covered by car in first two hours = 60 * 2.0 = 120 km.
Total distnace covered = 80 km + 120 km =200 km.
Total time taken = 2.0 + 2.0 = 4.0 hours.
Average velocity =
Plugging values in above formula, we get
= 50 km/h
Therefore, average velocity is 50 km/h.
A motion in one dimension is a type of motion that is always along a straight line and has a constant acceleration.
Motion refers to a change in the location (position) of an object or physical body with respect to a reference point, especially due to the action of an external force.
In Science, the motion of an object or physical body is described in terms of the following parameters:
Furthermore, there are three (3) forms of motion based on dimension and these include:
1. Motion in one dimension
2. Motion in two dimension
3. Motion in three dimension
A motion in one dimension (one-dimensional motion) is also referred to as rectilinear or linear motion. Also, it is always along a straight line in any direction and characterized by constant acceleration.
