Because the scientific method can go around in a circle as many times as neccisary to get the results you need
Answer:
Convection
Explanation:
Convection: the lighter warm air moves up and the heavier cold air moves down.
Answer: all 3 of these can affect barometric pressure
(cause a low pressure zone)
Explanation:
Answer:
6.78 km
Explanation:
Length of path due east = 4.3km
Length of path south = 2.48km
Unknown:
Distance covered = ?
Solution:
The distance covered is the total length of path from start to finish. It takes cognizance of the turns and every direction moved.
Unlike displacement which only considers the net direction from start to finish, distance sums up the total path.
So;
Distance = 4.3km + 2.48km = 6.78km
Answer:
The question has the following answer options:
A. It decreases.
B. It increases.
C. It decreases then increases.
D. It does not change.
The correct answer is: D. It does not change.
Explanation:
The trajectory of a projectile is the path that a body follows when it has been thrown. It can be depicted in a coordinate system. Typically, the horizontal x axis stands for the distance that the object travels (in direction x) and the vertical and axis stands for the height (in direction y) of the throw. This very common form of movement is surprisingly simple to analyze if the following two assumptions are made:
1. The acceleration of free fall, g, is constant throughout the range of motion and is directed downward.
2. The effect of air resistance can be ignored.
With these assumptions, it is found that the curve that describes a projectile, and that it is known as its trajectory, is always a parable.
The horizontal velocity remains constant because in that direction the acceleration is zero.
