Answer from: xojade

The force acting on one of the sides the square loop is 169.6 N

The torque acting on the loop is ZERO

Explanation:

From the question we are given that

permeability of free space $\mu_0$ $= 4\pi*10^{-7} T\cdot m/A$

Number of turns of the solenoid per unit length , n = 30 turns per cm

= 3000 turns per m

The current flowing through the solenoid I_1 = 15A

Length of the side of the loop, L = 2 cm

= 2 cm [ $\frac{1*10^{-2}m}{1cm}$ ]

= $2*10^{-2} m$

Angle , $\theta =90$ °

The current flowing through the wire I_2 = 0.15A

Generally The formula for Magnetic field inside of a solenoid is

$B = \mu_0nI_1$

Where

$\mu_0$ is the permeability of free space

n is the number of turns of the solenoid per unit length

I_1 is the current through the solenoid

Also the formula for force acting on one of the sides of a square loop is

$F = BI_2Lsin \theta$

Where I_2 is the current through the wire ,

L is the length of the sides of the loop,and

$\theta$ is the angle between B and I_2

Substituting the given values into the first formula

$B = (4 \pi *10^{-7})(3000)(15)$

$= 5.65*10^{-2} T$

To obtain the force acting on the loop by substituting the appropriate value into the second formula

$F = (5.65*10^{-2}(0.15)(2*10^{-2}(sin90)))$

$169.6 \mu N$

The torque acting on the lop is zero because the

The forces on the loop are acting in the plane of the loop

These force are perpendicular to the sides

and their direction is away from the inner side of the loop

the only effect the orientation of these forces can cause is stretching of the loop

This way by which the forces are oriented cannot cause any rotation

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.
