Answer: The movement of tectonic plates
Explanation:
Tectonic plates are the part of the earth's crust that both the ocean and land rest on. These plates are constantly moving as a result of currents in the mantle.
These movements cause stress on the surface which has the effect of fracturing rocks and thereby creating/ forming faults in the earth's crust. Sometimes faults form when these plates move away from each other and sometimes they are formed when they push into each other.
Answer:
mainly used to combine two tables based on a specified common field between them. If we talk in terms of Relational algebra, it is the cartesian product of two tables followed by the selection operation. Thus, we can execute the product and selection process on two tables using a single join statement. We can use either 'on' or 'using' clause in MySQL to apply predicates to the join queries.
A Join can be broadly divided into two types:
Inner Join
Outer Join
Inner Join is a join that can be used to return all the values that have matching values in both the tables. Inner Join can be depicted using the below diagram.
The inner join can be further divided into the following types:
Equi Join
Natural Join
Now let us learn about these inner joins one-by-one.
Answer:
P= 541.5 kW.
Explanation:
Given that
velocity of water after leaving the nozzle ,v= 95 m/s
The mass flow rate of the water , m= 120 kg/s
The power generated P is given as
Now by putting the values in the above equation we get
P=541500 W
The power in kW will be 541.5 kW.
Therefore the answer will be 541.5 kW
P= 541.5 kW.
The tensile stress at the yield point is 286 MPa, the ultimate tensile stress is 509 MPa and the average stress is 1,018 MPa.
<h3>Tensile stress</h3>
I. Tensile stress at the yield point
Tensile stress=Fy/A1=4×90×10^3÷πd1²
=360×10^3÷(2×10^-2)²π
=286 MPa
II. Ultimate tensile stress
Fmax/A1=4×160×10^3÷πd1²
=640×10^3÷(2×10^-2)²π
=509 MPa
III. Average stress at the breaking point
Fd/A2=4×80×10^3÷πd2²
=320×10^3÷(10^-2)²π
=1,018 MPa
Therefore the tensile stress at the yield point is 286 MPa, the ultimate tensile stress is 509 MPa and the average stress is 1,018 MPa.

Answer:
0.59
Explanation:
based on Lever's phase rule, we can find the fraction of the α phase in the structure using the following formula:
where
= mass fraction of element B in the entire alloy or mixture = 40%
= mass fraction of element B in the β phase = 90%
= mass fraction of element B in the α phase = 5%
hence we have
∴ The fraction α phase in the structure is ≈ 0.59
