Answer:
Part a)
A = 0.0581 m
Part b)
T = 0.37 s
Explanation:
Slice is dropped on the plate from height 0.250 m
so the speed of the slice while it hit the plate is given as
here we know that
now from momentum conservation
from the above equation we have
Now the initial mean position while it will not hit the plate is given as
now when slice is placed on the plate then the new mean position will be given as
now we know that speed of SHM is given as
here we have
now from above formula
Part b)
Time period of scale is given as
Answer:2m/s²
Explanation: Well F=MA so sice F=4N and M=2kg let's plug in the values
4N=2KG*A
A=4N/2KG
A=2m/s²
Answer:
1. The subduction zone serves as the meeting point for two tectonic plates.
2. At the Mid- Ocean ridge, decompression melting occurs.
3 What causes the magma to rise is the increase in pressure caused by collection of gases by the magma.
Explanation:
Subduction zone is define as a zone where tectonic plates ( an oceanic plate slides beneath a continental plate) meets and contributes to the rise of magma to the surface in geological sciences.
At the Mid - Oceanic ridge, decompression melting occurs. As mantle ascends beneath the mid-ocean ridge, less and less rock lies above it, so large pressure changes occur, which leads to melting. The melt is less dense than the solid, and rises to the surface to form the oceanic crust.
At the subduction zone the magma that is formed is usually made up of silica rich lava. Thick silica rich magma does not release the gasses very easily so they build up inside the magma chamber. As the gasses collect in the chamber, the pressure rises. It is possible for the pressure to rise so much that the chamber cannot contain the magma and it erupts explosively.
the answer is the Spiral Galaxy
Both, there are two different types of molecules to distinguish that
