Answer:
The force is
Explanation:
From the question we are told that
The diameter of the wire is
The pressure is
Generally the radius of the of the wire is
=>
=>
The Area is evaluated as
=>
=>
Generally pressure is mathematically represented as
=>
=>
=>
The frequency of a sound is whatever frequency leaves the source. It doesn't change.
Voiced of swimmers at the pool don't change frequency in or out of the water. Only their speed and wavelength change.
Answer:
Explanation:
When the circuit elements are connected in series, the current in each element is same but the potential difference is different.
So, as one of the circuit component breaks off or burnt, all the other components are also not working as the circuit becomes open and no current is flowing through the circuit.
Answer:
(a) E=λ/(2\pi e0 r)
(b) E = 0
Explanation:
(a) We can use the Gaussian's Law to calculate the electric field at any distance r from the axis. By using a cylindrical Gaussian surface we have:
where λ is the total charge per unit length inside the Gaussian surface. In this case we have that the Electric field vector is perpendicular to the r vector. Hence:
(b) outside of the outer cylinder there is no net charge inside the Gaussian surface, because charge of the inner radius cancel out with the inner surface of the cylindrical conductor.
Hence, we have that E is zero.
hope this helps!!
Answer:
Explanation:
Technician A is incorrect as in series circuit the current is the same for all the resistors and if one bulb fails in the path then the circuit is incomplete and therefore no flow of current.
Technician B is correct as in parallel circuit there are multiple paths for current through which it can pass and malfunctioning of one resistor does not affect the other.
