Answer:
<em>Controlled variables</em>
Explanation:
In a controlled experiment, the control group and the experimental groups are the same except for a factor in the experimental groups called a. variable parameter. In a controlled experiment, the factors that are kept the same between groups are called. controlled parameters.
A)
Answer: They will fall at the same time.
Explanation: This is a free fall equation. Free fall equations don't use other factors such as air resistance or wind.
B)
Answer: 15m
Explanation:
Given: Vi = 10m/s
t = 1s
a = 10m/s/s
The equation you need to use is d = Vit + 0.5at^2
d = Vi t + 0.5 a t^2
d = (10 m/s) (1 s) + 0.5 (10 m/s^2) (1 s)^2
d = (10 m) + 0.5 (10 m/s^2) (1 s)^2
d = (10 m) + (5 m/s^2) (1 s)^2
d = (10 m) + (5 m/s^2) (1 s^2)
d = (10 m) + (5 m)
d = 15 m
Answer:
Atom
Explanation:
An atom is the most simple and basic form of matter which cannot be broken down any further.
I would conclude that Region 1 is an older portion of the surface than region 2.
The amount of clatering is usually an indication of the age of a geological surface; the more craters, the older the surface, because if the surface is young there hasn't been time for many craters to form. Therefore, Earth has a relatively young surface because it has few craters. This is because the Earth is geologically active, with plate tectonics and erosion having obliterated most craters from an earlier epoch. The surface of the moon on the other hand is much older with much more clatering. Additionally, different parts of the moon exhibit different amounts of clatering and thus are of different ages.
The answer is Energy cannot be created nor destroyed.
