Answer:
Transactional process
Explanation:
Because communication involves two or more people acting in both sender and receiver roles and because their messages are dependent on and influenced by those of their partner means that communication is a transactional process i.e. a give and take process.
If the sender relays a message and the receiver does not reply or reply not taking cognizance of the sender's message, communication has not taken place.
For example, if consider this.
Sender: How old are you?
Reciever: My Cat is Red.
The response of the receiver is not in tune with the sender and so communication has not taken place.
Answer:
1.526 m
Explanation:
The motion sensor sends sound waves in air which travels at a speed of 343 m per second at 20 degree. If d be the distance of the reflecting object
total distance travelled = 2d
Time taken t = 8.9 x 10⁻³ s
velocity v = 2d / t
343 = 2 d / (8.9 x 10⁻³)
d = 1.526 m
If the acceleration is centripetal then the formula is a=v^2/r
Plug in 58.8=v^2/.400 solve for v
V=12.12 m/s
One of the formulas for calculating electrical power is
Power = (voltage)² / (resistance)
Since this problem wants us to find the voltage, let's
re-arrange the formula.
Multiply each side by (resistance):
(Voltage)² = (power) x (resistance)
Take the square root of each side:
Voltage = √ (power x resistance)
THERE's the formula we can use to find the voltage for this problem.
Voltage = √ (2,083 W x 25.4 Ω)
Voltage = √ (52,908.2 W-Ω )
Voltage = 230 volts
