The drawing on the right shows a man (mass = 70kg) and the child (mass = 35 kg) push each other apart. The man moves away with a
speed of 0.3 m/s relative to the ice.
Calculate the velocity of the child relative to the ice.

Answer:
18 Ω
Explanation:
As K and F are at the same voltage, we can redraw the diagram as in figure 2
Series resistances add directly, so we get figure 3
Adding parallel resistances gets us to figure 4
Now we can move two 6Ω resistances for clarification in figure 5
As the voltage between C and J will be identically split between D and H, there will be no voltage drop across the middle 6Ω resister and no current through it, identical to an infinite resistance, so that 6Ω can be eliminated as in figure 6
Add series resistances to get to figure 7
Add parallel resistances to get to figure 8
Add series resistances to get to figure 9
Answer:
The maximum voltage is 39.08 V.
Explanation:
Given that,
Voltage = 550 V
Suppose, In an L-R-C series circuit, the resistance is 400 ohms, the inductance is 0.380 Henry, and the capacitance is
We need to calculate the resonant frequency
Using formula of resonant frequency
Put the value into the formula
We need to calculate the maximum current
Using formula of current
Put the value into the formula
We need to calculate the impedance of the circuit
Using formula of impedance
At resonant frequency ,
So, Z = R
We need to calculate the maximum voltage
Using formula of voltage
Put the value into the formula
Hence, The maximum voltage is 39.08 V.
