Answer:
See below
Explanation:
rho = R A/l R = resistance A = cross sectional area l = length
The distance formula:d = v i · t + a · t² / 2Sir G.: ( v i = 0 )
d G = 0 + 0.3 · t² / 2Sir A. : d A = 0 + 0.2 t² / 288 m = 0.3 t² / 2 + 0.2 t² / 2 / · 2 ( multiple both sides by 2 )176 = 0.3 t² + 0.2 t²176 = 0.5 t²t² = 176 : 0.5t² = 352t = √352t = 18.76 sd G. = 0.3 · 18.76² / 2 = 0.3 · 352 / 2 = 52.8 mAnswer: The knights collide at 52.8 m relative to Sir George`s starting point.
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
Answer:
screwdriver should be the awnser is what I think
It is balanced force nothing is being applied I did this already
