I believe a charged Atom is an ion. And that a charged atom possess it's charge due to the different number of electrons that it possess. Unlike an uncharged atom or neutral atom, a charged atom may possess more or less than the number of electrons found in an uncharged atom.
Answer:
(a) 0.017m/s^2
(b) 17/100,000
(c) 0.17m, 0.558ft
Explanation:
(a) speed = 60mph = 60m/1h × 1h/3600s = 0.017m/s, time = 10s
Acceleration (a) = speed ÷ time = 0.017m/s ÷ 10s = 0.0017m/s^2
(b) g = 9.8m/s^2, a = 0.0017m/s^2
a/g = 0.0017/9.8 = 0.00017 = 17/100,000
(c) Distance = speed × time = 0.017m/s × 10s = 0.17m
Distance in foot = 0.17 × 3.2808ft = 0.558ft
Answer:
Golf ball A was hit with a weaker force
Explanation:
Golf ball B went a larger distance than golf ball A, so we could think friction affected golf ball A rather than golf ball B. That is why the first two choices are wrong.
The strongest forced applied made golf ball B go further.
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.
Given,
Initial Velocity (u) = 0 m/s
Final Velocity (v) = 25.9 m/s
Time (t) = 2.5 sec
avg. acceleration = ?
avg. acceleration = v-u/t
avg = 25.9/2.5 = 10.36 m/s²
avg = 10.36 m/s²
