If any current is PRODUCED in an individual home, like with
a windmill or solar panels, it is direct current (DC).
The current SUPPLIED to homes by the local utility company
is alternating current (AC).
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options. However, one material that is good candidate for conducting electricity without reacting with other materials is metallic vanadium dioxide. This is because of the inability of this electrical conductor to conduct heat (an unusual property for all other electrical conductors) and thus makes it difficult for it to react with other materials (since an increase in temperature increases possibility of a reaction).
Kepler’s
third law formula: T^2=4pi^2*r^3/(GM)
We’re trying to find M, so:
M=4pi^2*r^3/(G*T^2)
M=4pi^2*(1.496
× 10^11 m)^3/((6.674× 10^-11N*m^2/kg^2)*(365.26days)^2)
M=1.48× 10^40(m^3)/((N*m^2/kg^2)*days^2))
Let’s work
with the units:
(m^3)/((N*m^2/kg^2)*days^2))=
=(m^3*kg^2)/(N*m^2*days^2)
=(m*kg^2)/(N*days^2)
=(m*kg^2)/((kg*m/s^2)*days^2)
=(kg)/(days^2/s^2)
=(kg*s^2)/(days^2)
So:
M=1.48× 10^40(kg*s^2)/(days^2)
Now we need to convert days to seconds in order to cancel
them:
1 day=24 hours=24*60minutes=24*60*60s=86400s
M=1.48× 10^40(kg*s^2)/((86400s)^2)
M=1.48× 10^40(kg*s^2)/(
86400^2*s^2)
M=1.48× 10^40kg/86400^2
M=1.98x10^30kg
The
closest answer is 1.99
× 10^30
(it may vary
a little with rounding – the difference is less than 1%)
Answer:
The correct answer is: b. Channel
Explanation:
The Communication Process Model (CPM) is a model that describes the steps through which effective exchange of information takes place from the sender of a message to the receiver(s) of the message. (Refer to attached image)
The CPM includes the following steps:
1. Noise- reducing physical/ physiological distractions that can impede clear communication.
2. Communicator- the person who initiates the communication
3. Message- the information exchanged between the sender and receiver of the message
4. Feedback- How the information from the sender is received by the recipient of the communication
5. Channel- The medium by which the information is delivered from the sender to the receiver.
In this instance, when Aaden decided to have a discussion with his significant other in his home using face-to-face communication, he is deciding on the channel or medium through which the communication will this place. By choosing face-to-face communication at his home, Aaden has determined what he believes is the most appropriate context for the conversation with his significant other, given the sensitive nature of the topic. In this way, Aaden has selected a channel of communication.
