Answer:
Sound energy (that is, mechanical vibrational waves passing through an elastic medium) is a combination of kinetic and potential energies. As the wave compresses the medium (storing elastic potential energy) the medium comes to rest (no motion so no kinetic energy).
Explanation:
Hope this helps :D
<span>The reason that things look wavy in the heat over a hot grill or stove is that the air temperature is not stable. Hot air naturally rises, so as air comes off the hot surface, it rises for a bit before rapidly cooling and sinking to be heated again. This constant mixing of hot and cool air produces vibration. This vibration affects how we see the light moving through the air, making it look wavy.</span>
To solve the problem it is necessary to have the concepts of the magnetic field in a toroid.
A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials.
By definition the magnetic field is given by the equation,
Where,
= Permeability constant
N = Number of loops
I = Current
r = Radius
According to the given data we have that the length is 120mm and the thickness of the copper wire is 4.82mm.
In this way the number of turns N would be
On the other hand to find the internal radius, we know that:
Therefore the total diameter of the soda would be
Applying the concept related to magnetic field you have to for the internal part:
The smallest magnetic field would be on the outside given by,
<em>Therefore the maximum magnetic field is 0.06T.</em>
Answer: r= 0.04meter
Explanation:
The velocity V and angular speed w is related to the radio by
V=w*r
r=V/w
But the standard unit for velocity is m/s so we convert 57.3cm/sec to m/s
57.3/100= 0.57m/s
Also Angular speed w is rad/secs
So we convert rev/min to rad/sec
0.1rad/sec equals 1 rev/mins
141rev/mins * 0.1rad/secs
=14.1rad/sec
r = V/w
= 0.573/14.1
= 0.04m to 2d.p
