The mocking energy consumption because manufacturing and consumption are related
Answer:
a)
b)
Explanation:
The current flowing in a R-L series circuit is given by
Where τ is the time constant and is given by
Where L is the inductance and R is the resistance
Assuming the current has reached steady state when it is at 99% of its maximum value,
Therefore, it would take t = 4.6τ to reach the steady state.
(b) If an emergency power circuit needs to reach steady state within 1.2 ms of turning on and the circuit has a total resistance of 72 Ω, what values of the total inductance of the circuit are needed to satisfy the requirement?
Therefore, an inductance of 0.0187 H is needed to satisfy the requirement.
Explanation:
the notmal focrce stopped it.
The experiments that claimed to demonstrate cold fusion were found
to have been faulty by others who reviewed them. Also, nobody else
was
able to reproduce the finding in other laboratories. In the world
of
Science, this pretty much says that the initial claims were unfounded.
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.
