A conductor carrying 14.7 amps of current is directed along the positive x-axis and perpendicular to a uniform magnetic field. A

Gnoma [55]

Explanation:

It is given that,

Current carried in the conductor, I = 14.7 A (+x axis)

The magnetic force per unit length on the conductor, $\dfrac{F}{L}=0.125\ N/m$ (-y axis)

The magnetic force is given by :

$F=ILBsin\theta$

$\theta=90$

$F=ILB$

$B=\dfrac{F}{IL}$

$B=\dfrac{0.125}{14.7}$

B = 0.0085 T

According to right hand rule, the direction of magnetic force can be calculated. So, the direction of magnetic field is along +z axis. Hence, this is the required solution.

Star A and Star B have measured stellar parallax of 1.0 arc second and 0.75 arc second, respectively. Which star is closer? How

zhuklara [117]

Answer:

Star A is closer than Star B

Explanation:

As we know that in parallax method of distance measurement the angle subtended by the star when it covers a distance of one Parsec arc length, it is known as parallax angle

Here we can say

$angle = \frac{1 Parsec}{distance}$
