3.tom
Explanation:
Answer:
i think it is f i could be wrong-
cation
anion is negatively charged, so more electrons then protons,
cation is positively charged, so more protons thatn electrons
Answer:
The time constant becomes twice.
Explanation:
= Time constant of the L-R circuit
= Inductance of the inductor
= Resistance of the resistor
Time constant of the L-R circuit is given as
= initial time constant of the L-R circuit =
= final time constant of the L-R circuit
= Initial inductance of the inductor =
= Initial inductance of the inductor = 
For the same resistance, the time constant depend directly on the inductance, hence
lf a heavy point mass is suspended by a weightless, inextensible and perfectly flexible string from a rigid support, then this arrangement is called simple pendulum.
In practice, however, these requirements cannot be fulfilled. So we use a practical pendulum.
A practical pendulum consists of a small metallic solid sphere suspended by a fine silk thread from a rigid support. This is the practical simple pendulum which is nearest to the ideal simple pendulum.
Note :
The metallic sphere is called the bob.
When the bob is displaced slightly to one side from its mean position and released, it oscillates about its mean position in a vertical plane.
