Tangential acceleration of a point on the rim of the flywheel during this spin-up process is 0.2548 m/s².
Tangential acceleration is defined as the rate of change of tangential velocity of the matter in the circular path.
Given,
Radius of flywheel (r) = 1.96 cm = 0.0196m
Angular acceleration (α)= 13.0 rad/s²
The tangential acceleration formula is at=rα
where, α is the angular acceleration, and r is the radius of the circle.
using the formula; at=rα = (13.0 rad/s²) (0.0196m) = 0.2548 m/s².
The tangential acceleration is 0.2548 m/s².

Answer:
b)1 :3
Explanation:
Lets that
The value of a positive charge = q
As we know that electric filed on a point charge given as

Where ,K=Constant
q=Charge ,r=Distance
If the value of the charge gets tripled ,q'= 3 q
Then electric filed E'


E' = 3 E
Therefore we can say that

therefore the answer will be --
b)1 :3
I beleive she isnt doing any work due to holding the box motionless, you must be exerting a force in the direction of the box motion. If she is just standing there holding the box their isn't no work becuase no distance has been covered. work = force = distance.
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.
