Answer:
Double time = 65.42 years
Explanation:
We can find what year the human population would double using the rule of 70. This is given as;
Double time = 70 / rate(r)
From the question;
Double time = ?
Rate = 1.07%
Inserting into the equation;
Double time = 70 / 1.07
Double time = 65.42 years
Answer:
This process is known as doping. It can be done by adding either of two types of impurity to the crystal. (A) By adding electron rich impurities i.e., group 15 elements to the silicon and germanium of group 14 elements.
Answer:
e. adiabatic process
Explanation:
Adiabatic process -
In the thermodynamic system , an adiabatic process is the one which involves no transfer of mass or heat of the substance , is referred to adiabatic process.
In this process , the temperature need not be constant ,
But only the heat is transferred into or out of the system .
Hence, from the given information of the question,.
The correct option is e. adiabatic process .
30% should be the percentage of oxygen if the total mass of fe2o3 is 160.
