In this order terrestral, rocky, Venus, Earth
Answer:
Primitive material was formed in the early stage of the solar system, before planets cooled off enough to differentiate elements of different density. It was not subject to great heat or pressure after it formed.
We can identify primitive meteorites by their composition, primitive meteorites are usually undifferentiated stones, with some metallic grains mixed in. Some primitive meteorites are darker, carbonaceous stones.
Answer:
A. The starting height of the ball
Explanation:
When we talk about controlled variables, we refer to the variable that should be kept the same throughout the experiment. The reason why we do this, is to limit anything else that is not being tested, that may affect the results of the experiment.
In the scenario given, the experiment is to see the relationship between the <u>initial height of a basketball</u> and the <u>height of its rebound bounce. </u>
So you the starting height of the ball should vary, meaning it is NOT controlled.
Answer:
- 0.75 m
Explanation:
Using the graph as a reference point, the question is ;
What is the displacement of the elephant between 8s and 24s?
The displacement will be the sum of the slope of the graph within the given time.
From time 8s to 16s, the slope m will be;
Slope = (15 - 6) / (16 - 8)
Slope = 9 / 8
From time 16s to 24s
Slope = (15 - 0) / ( 16 - 24)
Slope = -15 / 8
Displacement = 9/8 - 15/8
Displacement = -6/8
Displacement = - 0.75 m
