40kg
Explanation:
Given parameters:
Kinetic energy = 500J
Velocity = 5m/s
Unknown:
Mass of the object = ?
Solution:
Kinetic energy is the energy due to motion of a body. It is expressed as:
K.E = 
mv²
m is the mass of the body
v is the velocity
To find the mass, make it the subject of the expression:
m = ![\frac{2 K.E}{v[tex]^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20K.E%7D%7Bv%5Btex%5D%5E%7B2%7D)
}[/tex]
m = ![\frac{2 x 500}{5[tex]^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20x%20500%7D%7B5%5Btex%5D%5E%7B2%7D)
}[/tex] = 40kg

The answer is that it tells you how flexible your muscles are
To give a solution to this exercise, it is necessary to apply Gauss's magnetic law in which he proposes the magnetic flux through closed surface is zero.
Our data given are as follows:
Inward flux = 13Wb
Outward flux = 22Wb
Since the field of the second flow is directed OUT of the curved side we need to subtract the values, therefore,
Flux = 22-13
