Answer:Speed of sound in steel is 6510m/s.
Explanation:
Speed, v= frequency,f÷ wavelength
v=?, f= 620, wavelength= 10.5
v= 620× 10.5
= 6510m/s

Explanation:
Answer:
Which means that the flux through each loop of the second coil is half as much as flux through each loop of first coil.
Explanation:
The flux through each loop of the first coil due to current in the second coil is,
The number of loops in the first coil is
no. of loops = 2N
Total flux passing through the first coil is
The flux through each loop of the second coil due to current in the first coil is,
The number of loops in the second coil is
no. of loops = N
Total flux passing through the second coil is
Comparing both
Which means that the flux through each loop of the second coil is half as much as flux through each loop of first coil.
Imagine this, you hear an ambulance, The ambulance is about a mile off and it isn't very loud. As it gets closer it gets louder and louder when it passes you it gets loudest then it is very quiet. So yes, your hypothesis was correct.
Answer with Explanation:
Concepts and reason
The concept to solve this problem is that if a capacitor is connected in a RC circuit then it allows the flow of charge through circuit only till it gets fully charged. Once the capacitor is charged it will not allow any charge or current to flow.
Opposite is the case with inductor in the RL circuit. According to Faraday's law an inductor develops an emf to oppose the voltage applied but once the flux change stops then the inductor behaves just like a normal wire as if no inductor is there.
In attached figure, resistor is connected in series to the capacitor.
As we considered the voltage across the capacitor and the voltage across the source.
Voltage across a resistor In RC circuit.
Voltage across a resistor In RL circuit.
