Answer:
The maximum magnetic field strength is 833.33 T
Explanation:
The maximum magnetic field strength is equal:
![B=\frac{E}{c}](https://tex.z-dn.net/?f=B%3D%5Cfrac%7BE%7D%7Bc%7D)
Where
E = electric field strength = 2.5x10¹¹V/m
c = speed of the light = 3x10⁸m/s
Replacing:
![B=\frac{2.5x10^{11} }{3x10^{8} } =833.33T](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B2.5x10%5E%7B11%7D%20%7D%7B3x10%5E%7B8%7D%20%7D%20%3D833.33T)
B. A machine changes the magnitude or direction of the force. Hope that helped.
Ek = 6KJ.
In physics, the kinetic energy of a body or object is the one that owns due to its movement and is given by the equation
, where m is the mass of the object in kilograms and v is the velocity in m/s.
An object that it has a mass of 30 kilograms and moves with a velocity of 20m/s, its kinetic energy is given by:
![E_{k} = \frac{1}{2} (30kg)(20m/s)^{2}=6000J=6KJ](https://tex.z-dn.net/?f=E_%7Bk%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2830kg%29%2820m%2Fs%29%5E%7B2%7D%3D6000J%3D6KJ)
