The answer is <span>oligotrophic</span>
In series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits.
And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
Option A and D
<u>Explanation:</u>
A circuit consists of number of passive and active devices in it. And depending upon the connections between the passive devices, the flow of current and potential drop across them will be specified.
Like if the passive devices are connected parallel to each other, the current flow through each device will vary but the voltage drop will be same. Similarly, if the passive devices are connected in series, then the current flow will be constant in the devices but the potential drop will vary.
Thus, in series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits. And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
Answer:
Explanation:
a ) Time period T = 2 s
Angular velocity ω = 2π / T
= 2π / 2 = 3.14 rad /s
Initial moment of inertia I₁ = 200 + mr²
= 200 + 25 x 2.5²
=356.25
Final moment of inertia
I₂ = 200 + 25 X 1.5 X 1.5
= 256.25
b ) We apply law of conservation of momentum
I₁ X ω₁ = I₂ X ω₂
ω₂ = I₁ X ω₁ / I₂
Putting the values
ω₂ = 4.365 rad s⁻¹
c ) Increase in rotational kinetic energy
=1/2 I₂ X ω₂² - 1/2 I₁ X ω₁²
.5 X 256.25 X 4.365² - .5 X 356.25 X 3.14²
= 684.95 J
This energy comes from work done against the centripetal pseudo -force.
Electrons flow from the positive end of a source towards the negative end
