Answer: Option (2) is the correct answer.
Explanation:
Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
For example, honey has high viscosity.
Whereas a substance which has less viscosity is will be able to flow easily from one place to another.
For example, water has low viscosity.
So, when substance B is more viscous then it means it has high viscosity than substance A. Hence, substance B will flow slowly as compared to substance A.
Thus, we can conclude that substance B is found to be more viscous than substance A. This means that B flows slower at room temperature than A does.
63 hertz.
This is because a hertz is how often a sound wave repeats.
Answer:
36.22 mA
Explanation:
i1 = I , i2 = I, d = 8.2 cm = 0.082 m
Force per unit length = 3.2 nN/m = 3.2 x 10^-9 N/m
μo = 4 π × 10^-7 Tm/A
The formula for the force per unit length between the two wires is given by
F = μo / 4π x (2 i1 x i2) / d
3.2 x 10^-9 = 10^-7 x 2 x I^2 / 0.082
I = 0.0362 A = 36.22 mA
