First of all, we need to calculate the magnetic field generated by the wire at a distance r=3.90 cm=0.039 m, which is given by:
where I=8.60 A is the current. Substituting numbers in the equation, we find
And now we can calculate the force exerted on the electron, which is given by:
where 
is the charge of the electron and 
is its speed. Substituting data in the formula, we find
Newton’s 3rd law of motion
Answer: This is true
Explanation: v2=800/25= 32m/s
The tearing of paper is physical as it's still paper even when you tear it. A chemical reaction is when the substance is chemically change. ... When paper is burn, the cellulose in the air reacts with the oxygen to form carbon dioxide and water.
Therefore it's chemistry.
Water, deionized water, glycol/water solutions, and dielectric fluids such as fluorocarbons and PAO are the heat transfer fluids most commonly used in high performance liquid cooling applications.
Hope this helps!
