i got it right
This is about identifiers in a record referring to other records.
You can have many to one, one to one, many to many.
E.g., if you have two tables, Authors and Books, then a book record could have a reference to an author record. Since an author can write many books, this would be a many-to-one relationship.
Answer:
4000k-ohm to 10,000k-ohm
Explanation:
As we know that time constant for an RC circuit is t=RC
Putting the values of t we can get the range of varaiable resistor as;
t=RC
Putting t=2 we get the first value of the range for the variable resistor
2=R*0.500*10^-6
R=2/(0.500*10^-6)
R=4*10^6
R=4000k-ohm
Now putting t=5 we get the final value for the range of variable resistor
t=RC
5=R*0.500*10^-6
R=5/(0.500*10^-6)
R=10*10^6
R=10,000k-ohm
So variable resistance must be made to vary in the range from 4000k-ohm to 10,000k-ohm
Answer:
The energy source that does not use heat in the process of converting it to electricity is;
c. Sunlight
Explanation:
In converting Sunlight energy source to electricity, the photons in the light from the Sun excite electrons in the solar cells silicon layers, such that the electrons travel from n-type silicon layer to the p-type silicon layer creating electric potential energy that does work as the electrons flow back in the form of electricity from the p-type to the n-type silicon layer through an external circuit
If you go to a college website you will see the it has .edu in the URL extensions.
