Wave speed = frequency (in Hz) x wavelength (in m) so wave speed = 11 x 0.011 = 0.121 m/s
I’ve answered this problem before and there were 2 parts in
this problem.
The solution would be like this for this specific problem:
<span>A.
</span><span>Vf = Vi +
Vex*ln(Mi / Mf) </span><span>
<span>0.002 * 3e8m/s = 0 + 2000m/s * ln(Mi / Mf) </span>
<span>300 = ln(Mi / Mf) </span>
<span>1.9e130 = Mi / Mf </span></span>
<span>B.
</span><span>4000m/s =
2000m/s * ln(Mi / Mf) </span><span>
<span>2 = ln(Mi / Mf) </span>
<span>7.389 = Mi / Mf </span>
<span>Mf = Mi / 7.389 = 0.135*Mi<span> </span></span></span>
Answer:
There is a general trend of decreasing abundance with increasing atomic number, but elements with even atomic numbers tend to be more abundant than those with odd atomic numbers.
Explanation:
Answer: B
Explanation: The straight line shows the theoretical average of the actual velocity and the curved line show that it is less than the average velocity of the object within 6 seconds.
straight line:
3. 3,80
6. 6,160
curved line:
- 1,2
- 2,17
- 3,32
- 4,60
- 5,100
- 6,160
A.K.A.-- the only place where the straight line and the curved line meet at is only at coordinate 6,160.
