Answer:
Magnetic dipole moment is 0.0683 J/T.
Explanation:
It is given that,
Length of the rod, l = 7.3 cm = 0.073 m
Diameter of the cylinder, d = 1.5 cm = 0.015 m
Magnetization, ![M=5.3\times 10^3\ A/m](https://tex.z-dn.net/?f=M%3D5.3%5Ctimes%2010%5E3%5C%20A%2Fm)
The dipole moment per unit volume is called the magnetization of a magnet. Mathematically, it is given by :
![M=\dfrac{\mu}{V}](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B%5Cmu%7D%7BV%7D)
![\mu=M\times \pi r^2\times l](https://tex.z-dn.net/?f=%5Cmu%3DM%5Ctimes%20%5Cpi%20r%5E2%5Ctimes%20l)
Where
r is the radius of rod, r = 0.0075 m
![\mu=5.3\times 10^3\ A/m\times \pi (0.0075)^2\times 0.073\ m](https://tex.z-dn.net/?f=%5Cmu%3D5.3%5Ctimes%2010%5E3%5C%20A%2Fm%5Ctimes%20%5Cpi%20%280.0075%29%5E2%5Ctimes%200.073%5C%20m)
![\mu=0.0683\ J/T](https://tex.z-dn.net/?f=%5Cmu%3D0.0683%5C%20J%2FT)
So, its magnetic dipole moment is 0.0683 J/T. Hence, this is the required solution.
Answer:
(a) W=1.20×10⁴J
(b) U= -5.46×10⁴J
(c) Q= -4.26×10⁴J
Explanation:
Given that student does 1.20×10⁴J work
(a) W=1.20×10⁴J
Work done by student,so positive sign
During the process, his internal energy decreases by 5.46×10⁴J.
(b) U= -5.46×10⁴J.
As the Energy decreases therefore negative sign
For (c) Q
We know the formula
![Q=W+U\\Q=1.2*10^{4}+(-5.46*10^{4} )\\ Q=-4.26*10^{4}J](https://tex.z-dn.net/?f=Q%3DW%2BU%5C%5CQ%3D1.2%2A10%5E%7B4%7D%2B%28-5.46%2A10%5E%7B4%7D%20%29%5C%5C%20Q%3D-4.26%2A10%5E%7B4%7DJ)
Answer:
C. Up, equal to the can's weight
Explanation:
You are camping in the breathtaking mountains if Colorado. You spy an unopened diet soda can floating motionless below the surface of a lake. What is the direction and amount of force the water exerts on it?
A. Zero
B. Down, equal to the can's weight
C. Up, equal to the can's weight
D. Not enough information is given
from the principle of flotation which states that a
When a body displaces a weight of water equal to its own weight, it floats. : A floating object displaces a weight of fluid equal to its own weight. ... Archimedes' principle equates the buoyant force to the weight of the fluid displaced.
the upthrust (this is the upward vertical force exerted on an object in fluid)in the water equals the weight of the body in water it floats.
Answer:
In the table, 1=46.7 °C, 1=165 J, 2=819 J, 3=1510 J, and 4=2830 J.
Other experiments determine that the material has a temperature of fusion of
fusion =235 °C and a temperature of vaporization of vapor=481 °C.
If the sample of material has a mass of =8.60 g, calculate the specific heat when this material is a solid, and when it is liquid, l
