The correct answer is option C. insulator.
An insulator material<span> has a high resistivity and prevents the movement of electrons. It is a hindrance in the path of electrons & resists the current flow.
The conductor conducts electrons as it offers very less resistance. A battery provides voltage to the circuit.
Hence, option (c) is correct. </span>
Answer:
Current flowing in the cell will be equal to 0.1284 mA
Explanation:
We have given charge q = 3.70 C
And time through which charge is flowing = 8 hour
We know that 1 hour = 60 minutes, and 1 minute = 60 sec
So 1 hour = 60×60 = 3600 sec
So 8 hour = 8×3600 = 28800 sec
We know that current is rate time rate of flow of charge
So current
So current flowing in the cell will be equal to 0.1284 mA
Answer: 13.2 seconds.
Explanation: using equation of motion; S= ut +1/2at² where u = initial velocity=0
S= distance travelled
a = acceleration due gravity
t= time.
1 foot = 0.305m so,
S= 2860 feet =872.3m
S= ut+1/2 at²
872.3 = 0×t + 1/2×10 × t²
872.3 =0 + 5t²
T²= 872.3/5
T²= 174.46
Take the square root of T we then have;
t = 13.2 seconds to one decimal place.
Answer:
306.08 kPa
Explanation:
Given data
Average stress of first wave = 3811 kPa
amplitude of first wave ( A1 ) = 430 kPa
Frequency of first wave = 6 Hz
<u>Determine the average stress of the second sinusoidal component in kPa </u>
Amplitude of the additional wave (A2add) = = 430 / 2 = 215 kPa
next we will determine the resultant amplitude of the second wave
A2 =
=
=
= = 480.79
hence the average stress of the second sinusoidal component
=
= = 306.08 kPa
