Answer: 4 is the subscript in 
.
Explanation:
We know that,
Subscript: The number of atom present in a given compound.
In , 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.
Coefficient: Number of atom which is used in reaction.
For example: In 
, 3 is the coefficient of silicon tetra chloride.
A Product : In the balance equation, right hand side is called product.
A reactant : In the balance equation, left hand side is called reactant.
For example: the balance equation is
In this equation, 
is the reactants and 
is products.
Hence, 4 is the subscript in .

Answer:
A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested. For some research projects, you might have to write several hypotheses that address different aspects of your research question
Explanation:
Answer:
I = 27.65A < 40.59°
PowerFactor = 0.76
Explanation:
Current on the heating load is:
I1 = 30KW / 4KV = 7.5A < 0°
Current on the inductive load:
I2 = (150KVA*0.6) /4KV = 22.5A with an angle of acos(0.6)=53.1°
The sum of both currents is:
It = I1 + I2 = 7.5<0° + 22.5<53.1° = 27.65<40.59°
Now, the power factor will be:
pf = cos (40.59°) = 0.76
