Answer:
a) [tex]v=4.0m/s[/tex]
b) [tex]B=2.958T[/tex]
Explanation:
From the question we are told that:
Wire Length [tex]l=10cm=>0.10m[/tex]
Resistance [tex]R=0.35[/tex]
Force [tex]F=1.0N[/tex]
Power [tex]P=4.0W[/tex]
a)
Generally the equation for Power is mathematically given by
[tex]P=Fv[/tex]
Therefore
[tex]v=\frac{P}{F}[/tex]
[tex]v=\frac{4.0}{1.0}[/tex]
[tex]v=4.0m/s[/tex]
b)
Generally the equation for Magnetic Field is mathematically given by
[tex]B=\frac{\sqrt{PR}}{vl}[/tex]
[tex]B=\frac{\sqrt{4*0.35}}{4*0.10}[/tex]
[tex]B=2.958T[/tex]
