Answer:
they are;at first its teamwork,then agility and quick thinking
My best guess would be b) You get a North pole magnet and a South pole magnet
hope this helps!
The time interval it would take a transverse wave to travel the entire length of the two wires is equal to 0.3295 seconds.
<u>Given the following data:</u>
- Length of steel wire = 30.0 m.
- Length of copper wire = 20.0 m
- Diameter of copper wire = 1.00 mm to m = 0.001 m.
- Diameter of steel wire = 1.00 mm to m = 0.001 m.
<u>Scientific data:</u>
- Density of steel = 7860 kg/m³.
- Density of copper = 8920 kg/m³.
<h3>How to determine the time interval?</h3>
First of all, we would determine the speed of the wave of steel wire and copper wire respectively.
For the speed of the wave of steel wire, we have:
Mathematically, the speed of a wave of steel wire can be calculated by using this formula:
Vs = √[T/(ρπd²/4)]
Vs = √[150/(7860 × 3.142 × 0.001²)/4)]
Vs = √(150/0.0062)
Vs = √24,193.55
Speed, Vs = 155.54 m/s.
For the speed of the wave of copper wire, we have:
Mathematically, the speed of a wave of copper wire can be calculated by using this formula:
Vc = √[T/(ρπd²/4)]
Vc = √[150/(8920 × 3.142 × 0.001²)/4)]
Vc = √(150/0.0070)
Vc = √21,428.57
Speed, Vc = 146.39 m/s.
Now, we can determine the time interval:
Time = t₁ + t₂
Time = Ls/Vs + Lc/Vc
Time = 30.0/155.54 + 20.0/146.39
Time = 0.1929 + 0.1366
Time = 0.3295 seconds.

#SPJ4
Answer:
The time is 0.5 sec.
Explanation:
Given that,
Voltage V= 12.00 V
Inductance L= 1.20 H
Current = 3.00 A
Increases rate = 8.00 A
We need to calculate change in current
We need to calculate the time interval
Using formula of inductor
Where, 
= change in current
V = voltage
L = inductance
Put the value into the formula
Hence, The time is 0.5 sec.
Answer:
Conductivity probe
Explanation:
The Conductivity Probe consists of two electrodes(also referred to as probes)or an electrode and a wall vessel where the material in the vessel completes the circuit as the level rises in the vessel.
It is used in measuring solution conductivity or total ionic concentration of aqueous samples.
