Answer:
These 5 principles can be better understood from the past events as well as from formation of the sedimentary rocks
Explanation:
Principle of original horizontal- the sedimentary rocks are found to be horizontal during the initial deposits phase. If tilted this is due to the subsequent geological event.
Principle of original lateral continuity- The sedimentary beds are originally laterally continuous into their environment of deposition. Faulting in the severe folding and also erosion may leads to the separation of the originally lateral continuous beds which in later becomes separate units.
Principle of cross cutting- The younger features can get cuts across the older features. That's why faults, erosion, volcanoes etc can be seen. The above mentioned are younger than those materials that is faulted intruded, or eroded.
Principle of inclusion- Inclusion itself means (a rock fragment another rock fragment) they must be older than the materials in.
Principle of uniformity- Those are the physical process that are been seen today, were also worked in the same way in the geologic past, thus modern methods helps us to understand the ancient events.
True, an object at rest stays and rest and an object in motion stays in motion
Answer:
(C) Decreases by factor of 3
Explanation:
Centripetal acceleration is given by
where <em>v</em> is the linear velocity and <em>r</em> is the radius of the curve.
Let the centripetal acceleration on the curve of radius <em>R</em> be 
.
Then
Let the centripetal acceleration on the curve of radius 3<em>R</em> be 
.
Then
Here, we see that the acceleration decreases by a factor of 3.
The wave will decrease in its frequency due to a disturbing force acting upon it.
The suns right ascension on the vernal equinox is (a) 0 hours
