Answer:
The potential difference at the customer's house is 117.1 V.
Explanation:
a) The potential difference at the customer's house can be calculated as follows:
<u>Where</u>:
: is the potential difference at the customer's house
: is the potential difference from the main power lines = 120 V
: is the potential difference from the lines
The resistance, R, is:
Now, the potential difference at the customer's house is:
Therefore, the potential difference at the customer's house is 117.1 V.
I hope it helps you!
Answer:
(a) 
(b) 
Explanation:
(a) Since a constant external force is applied to the body, it is under an uniformly accelerated motion. Using the following kinematic equation, we calculate the final velocity of the mass if it is initially at rest(
):
According to Newton's second law:
Replacing (2) in (1):
(b) In this case we have 
. So, we use the final velocity equation:
D. Pragmatism applies to everyone, but utilitarianism is concerned with the upper class.
