Answer:

v = 4.03 m/s

Explanation:

It is given that,

Distance covered by a lizard, d = 2.1 m

Time taken by lizard, t = 0.52 s

We need to find the average speed of the lizard. The distance covered divided by time taken is called the average speed of lizard. So,

v=\dfrac{d}{t}\\\\v=\dfrac{2.1\ m}{0.52\ s}\\\\v=4.03\ m/s

So, the average speed of the lizard is 4.03 m/s.

Two long straight wires are parallel and 8.6 cm apart. They are to carry equal currents such that the magnetic field at a point
Neko [114]

Answer:

(a) The current should be in opposite direction

(b) The current needed is 39.8 A

Explanation:

Part (a)

Based, on right hand rule, the current should be in opposite direction

Part (b)

given;

strength of magnetic field, B = 370 µT

distance between the two parallel wires, d = 8.6 cm

B = \frac{\mu_oI}{2\pi R}

At the center, the magnetic field strength is twice

B_c = 2(\frac{\mu_oI}{2\pi R}) =\frac{ \mu_oI}{\pi R}

R = d/2 = 8.6/2 = 4.3 cm = 0.043 m

B_c = \frac{ \mu_oI}{\pi R}\\\\I = \frac{B_c\pi R}{\mu_o} = \frac{370 *10^{-6}* \pi *0.043}{4\pi *10^{-7}}\\\\I = 39.8 \ A

Therefore, current needed is 39.8 A
