explain Tides
Answer / guest
Tides:- It is the alternating rise and fall of the surface
of the sea (approximately twice a day) caused by the
gravitational attracting pull of the moon and also to a
lesser degree of the sun. The rising water is called the
flood tide and the falling water is called the ebb tide. The
tides caused on the full nights ate higher than those caused
in other nights, and the tides in the mid-nights are also
higher than the day time.
There are two types of tides:-
(i) Spring tide:- On the full moon day the sun and the moon
move in a line in the same direction; their combined fore of
attraction causes a very high tide rather than on any other
day. This tide ie called the Spring tide
(ii) Neap tide:- On the say when moon comes in a position at
right angled to the sun, a bit higher tide occur which os
called the Neap tide

I want to prepare a frequency generator. the specifications i.e. output requirements are 12V, 1-10A & frequency upto 1K to 5K. Please, inform me with proper circuit dig. & the component values.
A coil consisting of 200 turns of wire has its ends connected to a circuit such that the total resistance of the coil and the circuit is 2.0 ohm. There is no source of e.m.f. in the circuit. Each turn of the coil is a square of side 18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from 0 to 0.5 T in 0.8 s, what is the magnitude of the current in the coil while the field is changing?
