Answer:
The value is 
The direction is into the surface
Explanation:
From the question we are told that
The mass density is 
The coefficient of kinetic friction is 
The current the wire carries is 
Generally the magnetic force acting on the wire is mathematically represented as
Here 
is the frictional force which is mathematically represented as
While 
is the magnetic force which is mathematically represented as
Here 
is the angle between the direction of the force and that of the current
So
So
=> ![B = \mu_k * \frac{m}{L} * [\frac{g}{I} ]](https://tex.z-dn.net/?f=B%20%20%3D%20%20%5Cmu_k%20%2A%20%20%5Cfrac%7Bm%7D%7BL%7D%20%2A%20%5B%5Cfrac%7Bg%7D%7BI%7D%20%5D)
=> ![B = 0.25 * 0.117 * [\frac{9.8}{1.24} ]](https://tex.z-dn.net/?f=B%20%20%3D%20%200.25%20%2A%20%200.117%20%20%2A%20%5B%5Cfrac%7B9.8%7D%7B1.24%7D%20%5D)
=>
Apply the right hand curling rule , the thumb pointing towards that direction of the current we see that the direction of the magnetic field is into the surface as shown on the first uploaded image
I am fairly certain it's D. Good luck!
When resistance force on a lever increases, nothing happens automatically.
But if you want to keep lifting the load, then YOU must increase the force of
your effort in order to make it happen.
Answer:
λ = 1.86 x 10⁻⁴ m = 186 μm
Explanation:
The relationship between the wavelength and the frequency of a wave is given by the following equation:
where,
λ = wavelength of infrared radiation = ?
c = speed of infrared radiation = speed of light = 3 x 10⁸ m/s
f = frequency of infrared radiation = 1.61 THz = 1.61 x 10¹² Hz
Therefore,
<u>λ = 1.86 x 10⁻⁴ m = 186 μm</u>
