Answer:
O So you can ask questions about steps you do not understand.
Explanation:
One of the reasons why it is encouraged that the laboratory procedure must be read at the beginning of any type of experiment is familiarize the student with the experimental procedure. Also, questions that can help make the smooth running of the experiment to proceed can be cleared.
- It is to this regard that understanding laboratory procedures is very vital.
- Students must grasp the details of each steps of the experiment before proceeding with their investigation.
- Other critical information needed to set up the experiment can also be brought into the lime light.
Answer:
0.6275 metres
Explanation:
v = fl
125.5 = 200 * wavelength
125.5 / 200 = wavelength = 0.6275m
Wait I don't see the question... Can you comment me in it so I can see? I think it's a glitch or something..
We are told that 4.0
complete waves pass a fixed point in 10 seconds. Using these data, we can find the frequency of the wave, which is given by the number of complete cycles per second:
Now we can find the period of the wave, which is the reciprocal of the frequency:
So, the correct answer is (3) 2.5 s.
We know, E = 1/4π∈ * q/r²
Here, 1/4π∈ = 9 × 10⁹
q = 2 C
r = 0.4
Substitute their values,
E = 9 × 10⁹ * 2/(0.4)²
E = 9 × 10⁹ * 2/0.16
E = 9 × 10⁹ * 12.5
E = 112.5 × 10⁹ N/C
So, Your Final Answer would be 1.125 × 10¹¹ N/C
Hope this helps!
