DENIUS [597]

Answer:

if you like my answer markme barinlest:)

Explanation:

An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.

A single-turn circular loop of radius 14 cm is to produce a field at its center that will just cancel the earth's magnetic field
Olin [163]

Answer:

49 A

Explanation:

We are given that

Number of turns,N=1

Radius,r=14 cm=\frac{14}{100}=0.14 m

1 m=100 cm

Magnetic field,B=0.7 G=0.7\times 10^{-4} T

1G=10^{-4} T

\mu_0=4\pi\times 10^{-7} Tm/A

We know that magnetic field

B=\frac{\mu_0IN}{2\pi r}

Substitute the values

0.7\times 10^{-4}=\frac{4\pi\times 10^{-7}\times 1\times I}{2\pi\times 0.14}

I=\frac{0.7\times 10^{-4}\times 2\pi\times 0.14}{4\pi\times 10^{-7}\times 1}

I=49A
