8 0

Answer:

15 less mins will be used by Bob

Explanation:

This is because it takes Tim 2000/50= 40mins to type the whole work

While it takes Bob 2000/80= 25 mins

So the difference 40-25= 15mins

Will be 15mins

Two parallel wires are separated by 5.60 cm, each carrying 2.65 A of current in the same direction. (a) What is the magnitude of
ololo11 [35]

Explanation:

It is given that,

The separation between two parallel wires, r = 5.6 cm = 0.056 m

Current in both the wires is 2.65 A

(a) We need to find the magnitude of the force per unit length between the wires. It can be given by :

\dfrac{F}{l}=\dfrac{\mu_o I_1I_2}{2\pi r}\\\\\dfrac{F}{l}=\dfrac{4\pi \times 10^{-7}\times 2.65\times 2.65}{2\pi \times 0.056}\\\\\dfrac{F}{l}=2.5\times 10^{-5}\ N/m

(b) As the current is in same direction, the wires will attract each other.

An electron in orbit around a (one proton) nucleus has a speed of about 106 m/s. Deduce the equivalent current due to the motion
dedylja [7]

Answer:

(a) -4.8\times 10^{-4}A (B) 4.22\times 106{-24}A/m^2

Explanation:

We have given the the speed of the electron =10^6 m/sec

The time period of the electron is given by T=\frac{2\pi r}{v} where r is the Bohr radius, which is equal to 5.29\times 10^{-11}m

So time period T=\frac{2\times \pi \times 5.29\times 10^{-11}}{10^6}=3.324\times 10^{-16}m/sec

(A) We know that current i=\frac{q}{T}=\frac{-e}{T}=\frac{-1.6\times 10^{-19}}{3.324\times 10^{-16}}=-4.8\times 10^{-4}A

(B) Magnetic moment is given by \mu =IA , where I is current and A is area

So \mu =IA=-4.8\times 10^{-4}\times 3.14\times (5.29\times 10^{-11})^2=4.22\times 10^{-24}A/m^2
