Answer:
c- the same
Explanation:
There will be apparent reduction in the weight of the apple due to buoyant force acting on it in upward direction . The magnitude of upward directing buoyant force will be equal to weight of water displaced . The weight of displaced water will remain same if it is completely submerged in water and it is moved from one point to another inside water. So in the given two cases , weight of displaced water will same . Hence the buoyant force too will remain same . Hence the apparent weight too will be same .
So force required to hold apple at deeper point inside water will remain same.
Answer:
TEJ as this is a thing you wont get
Answer:
by using graphical meythod
Given Information:
Wavelength of the red laser = λr = 632.8 nm
Distance between bright fringes due to red laser = yr = 5 mm
Distance between bright fringes due to laser pointer = yp = 5.14 mm
Required Information:
Wavelength of the laser pointer = λp = ?
Answer:
Wavelength of the laser pointer = λp = ?
Explanation:
The wavelength of the monochromatic light can be found using young's double slits formula,
y = Dλ/d
y/λ = D/d
Where
λ is the wavelength
y is the distance between bright fringes.
d is the double slit separation distance
D is the distance from the slits to the screen
For the red laser,
yr/λr = D/d
For the laser pointer,
yp/λp = D/d
Equating both equations yields,
yr/λr = yp/λp
Re-arrange for λp
λp = yp*λr/yr
λp = (5*632.8)/5.14
λp = 615.56 nm
Therefore, the wavelength of the small laser pointer is 615.56 nm.
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.
