What do you observe if you pour the water on the flat surface of a dinner plate?
When you pour water on the flat surface of a dinner plate, you will observe the water spreading out to cover the surface of the plate evenly due to surface tension. The water molecules are attracted to each other, causing them to stick together and form a thin layer. If the plate is clean and smooth, the water will form a cohesive layer without breaking apart.
Describe the construction of a kaleidoscope?
Construction of a kaleidoscope:Three rectangular mirror strips of dimensions 15cm × 4cm (l × b) are joined together to form a prism (fig a). This prism is fixed into a circular cardboard tube. The circular cardboard tube should be slightly longer that the prism (fig b). This circular tube is now closed at one end with a cardboard disc. This disc has a hole in it through which we can see (fig c) .At the other end of the circular tube, a plane glass plate is fixed. It is important that this glass plate touches the prism mirrors. On this glass plate, several small and broken pieces of coloured glass are placed. This end is now closed by a round glass plate allowing enough space for the coloured glass pieces to move (fig d).
Why do plate tectonics have names?
It is a suitable name because tectonics comes from the Greek word tekton which means builder, and plate tectonics refers to the building of the features on Earth's surface due to deformation caused by plate movements...
What is the process that brings fossil to the surface?
when a fossil is exposed at the earths surface, that means that weathering and erosions has exposed it or the movement of plate tectonics moved the earth and then the fossil is exposed that way.
Why fins are provided on heat transferring surfaces?
Using fins increases the surface area of the cover plate and more is the surface area meaning more place for heat dissipation or heat exchange. In simple words it multiplies the cooling effect.
Find the surface area of a plate?
surface area of glass plate
How do you measure and mention defects on plate?
You can measure defects on a plate with a 3-D surface map. To mention defects on a plate in a report you would want to include the shape, surface roughness, and surface finish of the plate.
What is a heat retentive plate?
A heat retentive plate is a plate made from either marble and plastic or ceramic which can be heated in a microwave and will then keep food hot for a period of time.
What is a plate with an ocean on the surface called?
Oceanic plate
What is the purpose of the plate?
A streak plate is used to determine the streak colour of a mineral. You take the mineral and scratch it against the streak plate, and it will create a coloured streak on the plate. The streak is not always the same colour as the mineral itself.
How does plates affect the surface of the surface?
when tectonic plate collides with other tectonic plates or moves into another tectonic plate it affects surface in a way to create mountains. Like Himalayas are created when the indian tectonic plate collided with asian tectonic plate.
How do colonies on the surface of a pour plate differ from those suspended in agar?
How do colonies on the surface of a pour plate differ from those suspended in the agar?
Is the first obvious signthat the nervous system is forming in the embryo is the thickening of the surface ectoderm to form the neural plate?
Yes, the thickening of the surface ectoderm to form the neural plate is one of the first visible signs that the nervous system is forming in the embryo. This process marks the beginning of neurulation, during which the neural plate folds and eventually closes to form the neural tube, from which the brain and spinal cord develop.
Where does marble rock come from?
Marble rock is derived from limestone that has been subjected to high heat and pressure within the Earth's crust. This metamorphic process causes the limestone to recrystallize into marble, resulting in its characteristic appearance and durability. Marble is typically found in mountainous regions where tectonic forces have caused these high temperatures and pressures to occur.
What is the surface area of a 15cm plate?
The surface area of a 15cm plate can be calculated using the formula for the surface area of a circle, which is A r2. Since the plate is circular, the radius (r) would be half of the diameter, which is 15cm. Therefore, the surface area would be A (7.5)2 176.71 square centimeters.
How many tectonic plates make up Earth's surface?
There are about 7 major tectonic plates that make up Earth's surface, including the Pacific Plate, North American Plate, Eurasian Plate, African Plate, Antarctic Plate, Indo-Australian Plate, and South American Plate.
How does the capacitance of parallel-plate capacitors with different surface areas vary?
The capacitance of parallel-plate capacitors increases with the surface area of the plates. This means that capacitors with larger surface areas have higher capacitance compared to capacitors with smaller surface areas.
