Answer:
The car has velocity and acceleration but is not decelerating
Explanation:
Since the car is traveling at 25 mph around the curve, it has a tangential velocity. This tangential velocity is constantly changing in direction (so the car could adapt to the curve and not moving forward in a straight line), there should be a centripetal acceleration in play here. This acceleration does not slow down the car so it's not decelerating.
Answer:
Obstructions can happen. Outside forces can act upon it.
Explanation:
Answer:
medium
Explanation:
A substance or particle that wave travel through is called medium. There are two main types of such medium, some contains particles and some are vacuums.
- Waves can travel through a vacuum which contains no particles.
- Some can also contain particles.
- Waves can interact in different ways with the medium.
Answer:
Human activity such as soil stripping, mining dangerous agricultural practice causes and affects erosion and sedimentation.
The earth operates a balanced process such that the earth produce it self at about the same rate as it erodes. So if humans are stripping the soil at a rate greater than the rate at which the soil is forming itself, the soil wont be able to keep up, thus leading to erosion.
Sedimentation on the other hand is the process whereby by particle settle at the base of the carrying body due to the force of gravity.
As humans, mining activity most importantly at times dissolves particles which travels down to the core and are then moved to another location by erosion. this implies that the strength of the soil of that location becomes weak.
A controlled experiment is best described as a safe, in depth, and insightful display that helps you understand the purpose of the experiment better
