Answer:
T= 4.24sec
Explanation:
We are going to use the formula below to calculate.

Where T is period
L is length of rod
g is acceleration due to gravity =
From the problem, the rod is pivoted at 1/4L which means that three quarter of the rod was used for the oscillation. lets call this

= 4.4625m
thus
T= 4.24sec
The inductance of a solenoid is given by:

where

is the vacuum permeability
N is the number of turns of the solenoid
A is the area of one loop of the solenoid
l is its length
For the solenoid in our problem, N=500, and the radius of one loop is r=0.025 m, so the area of one loop is

and its length is l=0.20 m
So the inductance of the solenoid is
Answer:
- Whenever current travels through a conductor, a magnetic field is generated. ... Depending on the shape of the conductor, the contour of the magnetic field will vary. ... Click the Reverse button to change the direction of the current flow ... to make a fist (or to wrap around the wire in question) is the direction of ...
Explanation:
Wave speed is 8 m/s
Explanation:
- Wave speed or speed of the wave is given by the formula
v = distance traveled by the wave/time
- Here, distance traveled = 16 m and time = 2 s
⇒ Wave speed = 16/2 = 8 m/s
