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.
Answer:
F = 3750 N
Explanation:
Given that,
Pressure, P = 150 Pa
Area, a = 25m²
We need to find the force applied. We know that, pressure is equal to the force acting per unit area. It can be given by :
So, the required force is 3750 N.
E=hf
E=6.626e-34[Js]•1500e3[Hz]=9.939e-28[J]
For eV divide this by electron charge
9.939e-28[J]/1.6022e-19[C/e]=
6.203e-9eV
Answer: When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.
Explanation:
Answer:
False
Explanation:
In the question it is given that a proton travels in the right moves in between the two plates. An electric field that is pointing in the vertically upward direction has magnitude of 3 N/C. The electric field is produced by the plates.
Now from here we can conclude that the direction of the force acting on the proton when the proton is in between the plates acts in the downward direction. While the electric field lines points in the upward direction. Thus the electric point will not be in the direction of the force that acts on the proton.
