Answer:
A) 209.12 GPa
B) 105.41 GPa
Explanation:
We are given;
Modulus of elasticity of the metal; E_m = 67 GPa
Modulus of elasticity of the oxide; E_f = 390 GPa
Composition of oxide particles; V_f = 44% = 0.44
A) Formula for upper bound modulus of elasticity is given as;
E = E_m(1 - V_f) + (E_f × V_f)
Plugging in the relevant values gives;
E = (67(1 - 0.44)) + (390 × 0.44)
E = 209.12 GPa
B) Formula for upper bound modulus of elasticity is given as;
E = 1/[(V_f/E_f) + (1 - V_f)/E_m]
Plugging in the relevant values;
E = 1/((0.44/390) + ((1 - 0.44)/67))
E = 105.41 GPa
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:
t= 0.75 s
Explanation:
Here given that there is no any external torque that is why it angular momentum will be conserve.
Initial angular momentum= m V₁ r₁
Final angular momentum= m V₂ r₂
So
m V₁ r₁ = m V₂ r₂
Now by putting the values
m V₁ r₁ = m V₂ r₂
V₁ r₁ = V₂ r₂
6 x 3 = 12 x r₂
r₂ = 1.5 ft
So the time t
t = r₂ / Vr
t= 1.5 / 2
t= 0.75 s
Mitochondria are the “powerhouses” of the cell breaking down fuel and capturing energy in cellular respiration. Chloroplasts are found in plants and aglae. The similarity is that they both responsible for capturing light energy to make sugars in photosynthesis
