The answer is to increase energy. Hope this helps!
First let's convert the time in seconds:

The current is defined as the quantity of charge flowing through a certain section of a circuit per unit of time:

Using I=10 A, and

, we can find the amount of charge flown through the hair dryer in this time:

The charge of a single electron is

, so the number of electrons flown through the hair dryer is the total charge divided by the charge of a single electron:
Answer:
True
Explanation:
As the formula for magnitude of a vector v and their components
is

Since
, this means the sum of them,
, is always greater or equal to
