Answer:
People often overestimate the clarity of their intentions in their electronic communications because they underestimate the importance of tones of voice in communication.
Explanation:
Many factors intervene in communication together. We use words, we use non-verbal language through our gestures and attitudes, and we also use a certain tone of voice. If we focus on this last aspect, the tonality in the voice is decisive in many ways, which cannot be appreciated through electronic communications. With this we communicate emotions, attitudes and a degree of personal involvement. At the same time, the image we project on others largely depends on the tone of voice we have.

-Velocity is the speed of any moving object in a given direction, whilst Speed is the rate of an object's ability to move.
-Velocity can change if the direction or time is changed, the basic equation of velocity is: v = d/t
v - velocity
d - distance
t - time
If one of these factors change, it affects the other.
Hope this answers the question!
Answer: 24.1 mL
Explanation:
Initial volume V1 = 65 mL
Initial pressure P1 = 0.854 atm
Final volume of the gas V2 = ?
Final pressure of the gas P2 = 2.3 atm
Since, pressure and volume are involved while temperature is constant, apply the formula for Boyle's law
P1V1 = P2V2
0.854 atm x 65 mL = 2.3 atm x V2
55.51 atm mL = 2.3 atm x V2
V2 = (55.51 atm mL / 2.3 atm)
V2 = 24.1 mL
Thus, the final volume of the gas will be
24.1 mL
