A 100-kg astronaut is floating in outer space. If the astronaut throws a 2-kilogram wrench at a speed of 10 meters per second, w
sergey [27]

Since Astronaut and wrench system is isolated in the space and there is no external force on it

So here momentum of the system will remain conserved

so here we can say

m_1v_{1i} + m_2v_{2i} = m_1v_{1f} + m_2v_{2f}

initially both are at rest

so here plug in all values

0 = 100 v_{1f} + 2\times 10

v_{1f} = -0.20 m/s

so here the astronaut will move in opposite direction and its speed will be equal to 0.20 m/s

zzz [600]

The magnetic field midway between the two wires is 5.0*10^{-7} T.

It is given that Two long parallel wires carry currents of 20 A and 5.0 A in opposite directions. The wires are separated by 0.20 m.

We need to determine the magnetic field midway between the two wires.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

Magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge.

B=B1+B2

=\frac{4\pi *10^{-7}*20 }{2\pi R1} +\frac{4\pi *10^{-7}*5 }{2\pi R2}

= \frac{4\pi *10^{-7}*20 }{2\pi *0.10} +\frac{4\pi *10^{-7}*5 }{2\pi *0.10}

= 5.0*10^{-7} T

Hence, the magnetic field midway between the two wires is 5.0*10^{-7} T
