It can be disproved with <span>one reproducible experiment.</span>
Answer:
1 V / div
Explanation:
Solution:
- The vertical scale has eight divisions.
- If each division is set to equal 1 volt, the display will show 0 to 8 volts.
- This is okay in a 0 to 5 volt variable sensor such as a throttle position (TP) sensor.
- The volts per division (V/div) should be set so that the entire anticipated waveform can be viewed.
C should be the right answer! hopefully this helps!
3.
If the reaction forms a new substance it's a chemical reaction.
Answer:

Explanation:
Given that,
The instantaneous current in the circuit is giveen by :

We need to find the rms value of the current.
The general equation of current is given by :

It means, 
We know that,

So, the rms value of current is 2.12 A.
