Answer:
【 In vector form , if angle between velocity vector and acceleration vector is less than 90° and greater than 0° then it is positive acceleration and if it is less than 180° and greater than 90° then it is negative acceleration. If there is no acceleration vector then it is called zero acceleration. 】
When you first pull back on the pendulum, and when you pull it back really high the Potential Energy is high and the Kinetic Energy is low, But when up let go, and it gets right around the middle, that's when the Potential energy transfers to Kinetic, at that point the kinetic Energy is high and the potential Energy is low. But when it comes back up at the end. The same thing will happen, the Potential Energy is high, and the Kinetic Energy is low. Through all of that the Mechanical Energy stays the same.
I hope this helps. :)

Sound intensity = 1/(r^2)
That is Sound intensity is indirectly proportional to the distance. Therefore, sound becomes 9 times less intense.

Answer:
inductance per unit length is
Explanation:
The diagram of coaxial cable is shown on the first uploaded image
From the question we are told that
The radius of the inner conductor is a
The current passing through the first cylindrical conductors is = I
The current passing through the first cylindrical conductors is = - I
The radius of the outer conductor is b
According to Ampere's law
∮
=>
=>
The magnetic flux on the coaxial cable can be mathematically represented as
Now the emf induced in the coaxial cable is mathematically represented as
=>
=>
=>
substituting for
dividing through by
