Right hand Rule:
James clark Maxwell proposed a rule to search the direction of magnetic lines of force around a wire carrying current. This rule states.
"If a current carrying conductor is grasped in the Right hand in like as way that the thumb pointing in the direction of current, the fingers will circle around the conductor in the direction of current, the finger will circle around the conductor in the direction of magnetic field."
The retina – the light detector of the eye: The physical aspects of the retina: 1.The absorption of a light photons in a photoreceptor triggers an electrical signal to the bra
Sketch a graph showing the relationship among the magnetic field around a straight, current-carrying wire, and the distance from the wire. This is a graph of y = 1/x.
The current in a coil changes of 5A to 10A in 10 -2 s. Then an emf of 50 mill volts is induced in a coil neat it. Determine the mutual inductance of the coil.
1. What is the principle of gas filled detectors? 2. What are nuclear radiations or particle detectors?
For each element the number of neutrons in the nucleus can vary. Isotopes :Nuclei of given element with different numbers of neutrons.If they are not radioactive they called
Vector Addition The Order Does NOT Matter The question frequent arises as to the significance of the order in that the vectors are added. For example, if five vectors are added
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
