The figure shows an electromagnetic train signal. When it is switched on, the signal remains in the upward position, whereas when it is switched off, the signal remains in the downward position as shown in the figure. Which part of the electromagnetic train signal is the electromagnet?
Tempenny constructs a simple electric generator as shown in the figure. The part of the electric generator which is an electromagnet is the
The position versus time graph of the motion of a boy along a straight path is shown in the given figure. The total time for which the boy remains in motion is
It is found that all electromagnetic signals sent from A towards B reach point C inside the glass sphere, as shown in figure. The speed of electromagnetic signals in glass cannot be:
Figure shows a powerful electromagnet arrangement. A copper ring, which is free to move, is placed on the projecting part of the core as shown. When the key is inserted, the ring
Steve constructs an automatic door latch as shown in the figure. When the switch is closed, the electromagnet attracts the door latch toward itself and the door can be opened. When the switch is opened again, the door latch comes back to its original position using the spring attached between the core of the electromagnet and the door latch. Steve can improve the structure of the automatic door latch by
The internal construction of an electric bell is shown in the given figure. The switch is in OFF position. When it is switched ON, one part of the bell moves. The part that moves when the switch is closed is the
When a positive voltage signal is applied to the base of a common emitter npn amplifier
The velocity-time graph of a stone thrown vertically upward with an initial velocity of 30ms^(-1) is shown in the figure. The velocity in the upward direction is taken as positive and that in the downward direction as negative. What is the maximum height to which the stone rises?
