Answer:
no
Explanation:
it can't be probed it would be like probing a goat's butt
(20 miles) x ( 1/45 hour/mile) =
(20/45) (hour) = <em>
4/9 hour = </em>26 minutes 40 seconds
Answer:
The wavelength of the wave is
Explanation:
Lets calculate
We know an electromagnetic wave is propagating through an insulating magnetic material of dielectric constant K and relative permeability
,then the speed of the wave in this dielectric medium is
is less than the speed of the light c and is given by a relation
--------- 1
In case the electromagnetic wave propagating through the insulating magnetic material , the amplitudes of electric and magnetic fields are related as -

The magnitude of the 'time averaged value' of the pointing vector is called the intensity of the wave and is given by a relation

----------- 3
now , we will find the speed of the propagation of an electromagnetic wave by using equation 1

Putting the values ,
=
=
= 
Now , using this above solution , we will find the wavelength of the wave -

Putting the values from above equations -


Hence , the answer is 
Answer:
The Earth's magnetic field intensity is roughly between 25,000 - 65,000 nT (.25 -.65 gauss).
Explanation:
<em>To measure the Earth's magnetism in any place, we must measure the direction and intensity of the field. The Earth's magnetic field is described by seven parameters. These are declination (D), inclination (I), horizontal intensity (H), the north (X), and east (Y) components of the horizontal intensity, vertical intensity (Z), and total intensity (F). The parameters describing the direction of the magnetic field are declination (D) and inclination (I). D and I are measured in units of degrees, positive east for D and positive down for me. The intensity of the total field (F) is described by the horizontal component (H), vertical component (Z), and the north (X) and east (Y) components of the horizontal intensity. These components may be measured in units of gauss but are generally reported in nanoTesla (1nT * 100,000 = 1 gauss). </em><em>The Earth's magnetic field intensity is roughly between 25,000 - 65,000 nT (.25 - .65 gauss). </em><em>Magnetic declination is the angle between magnetic north and true north. D is considered positive when the angle measured is east of true north and negative when west. The magnetic inclination is the angle between the horizontal plane and the total field vector, measured positive into Earth. In older literature, the term “magnetic elements” is often referred to as D, I, and H.</em>
Reading of the scale will be given as Normal force on the man
So here we can say that
weight of the mas will be

normal force on the man will be given as

now net force is given by Newton's II law




a = 3.33 m/s^2
so elevator is accelerating downwards with an acceleration a = 3.33 m/s^2
