Answer:
The energy dissipated is 
Explanation:
From the question we are told that
The distance covered at constant velocity d = 2 m
The velocity is 
Generally at constant velocity the magnetic force on the bar is mathematically represented as
substituting values
The energy dissipated is mathematically evaluate as
substituting the value
Do you remember the formula for potential energy ?
PE = (mass) (gravity) (height)
If the mass and the height are always the same, then the least PE comes from the least gravity. Surely you can find THAT in the table.
In order for Ren who runs a harmburger stand and needed to clean up a season's worth of grease buildup, the cleaning product that he should look for that can handle a layer of grease would be those caustic chemicals. These caustic chemicals <span>can be applied to break down the grease. When these grease are broken down, hot water can be applied to rinse it.
