Answer:
Time period for Simple pendulum,
Explanation:
The Simple Pendulum
Consider a small bob of mass is tied to extensible string of length that is fixed to rigid support. The bob is oscillating in the plane about verticle.
Let is the angle made by string with vertical during oscillation.
Vertical component of the force on bob,
Negative sign shows that its opposing the motion of bob.
Taking as very small angle then,
Let is the displacement made by bob from its mean position ,
then,
so, ........(1)
Since, pendulum is in hormonic motion,
as we know,
where is the constant and
.........(2)
From equation (1) and (2)
Since,
It depends on their tension. Normally, the rubber band store more tension than a t shirt.
Answer:
The statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement
Explanation:
The net magnetic field at the center of this square is not equal to zero.
The net magnetic field at the center of this square is given by the equation below:
B = 2√2μ₀I/πₐ
Where a = the side of the loop, and I is the current.
Thus, the statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement because the total charge on the conductor must be equal to zero.
This is called an organ. Examples of organs are: your heart, brain, lungs, liver, stomach etc.
