Answer» Charge (Q) measured in coulomb (C), CURRENT (I) measured in amps (A) and time (t) measured in seconds (s).The AMOUNT of ELECTRICAL charge that moves in a circuit depends on the current flow and how LONG it flows for. For example, if a current of 10 A flows for 30 s, then 10 x 30 = 300 coulombs of electrical charge moves. This means Q = It. Now ENTER your values in to your calculator and have fun!

The groundA stone dropped from a tree takes 2 second to reach the ground'Find its velocity on string the groundTake g = 9.8 m/s²

Answer»

Answer:

19.6 m/s

Explanation:

Given data,

t = 2 sec

u = 0 m/s

g = 9.8 m/s^2

v = ?

Using the 2ND EQUATION of motion,

h = ut + 1/2 gt^2

h = 0 X 2 + 1/2 x 9.8 x 2 x 2

h = 1 x 9.8 x 2

h = 19.6 m

Now, we can find 'v' by using the 3rd equation of motion,

2gh = v^2 - u^2

v^2 - u^2 = 2gh

v^2 - 0^2 = 2 x 9.8 x 19.6

v^2 = 384.16

v = √384.16

v = 19.6 m/s

This magnetic field:[A] is unidirectional and has a steady magnitude[B] is unidirectional but its magnitude varies in regular pattern[C] has steady magnitude but changes direction in regular pattern[D] changes direction and magnitude in regular pattern
Answer» Answer: A coil or conductor carrying direct current (DC) produces a magnetic field similar to a permanent magnet. The current carried by this conductor is unidirectional and steady i.e. it does not CHANGE direction or vary in magnitude with respect to time. Hence, the effect is that of a permanent magnet which simply attracts objects near the coil. However, in case of Alternating current, the magnetic field changes direction, i.e. it becomes negative for the second half of the frequency cycle (50 CYCLES per second in India). Further, its magnitude varies sinusoidally (curve having a sinewave form) thereby BECOMING ZERO at the end of a cycle. .. HOPE it's helps..
