Crafty Classes answered |
Viral or bacterial infections are recognized as potential triggers for Guillain-Barré Syndrome. In many cases, after an infection, the immune system may mistakenly attack the body's nerves, leading to the symptoms associated with GBS. While the exact mechanisms remain unclear, it is important to note that GBS can also occur following vaccinations or surgeries, although such instances are rare. This highlights the complex relationship between the immune system and neurological health.

Pallavi Nair answered • Sep 14, 2024 |
Understanding Magnetic Moment
The magnetic moment (m) of a material can be calculated using the formula:
m = M × V
Where:
- M = Magnetization (in units)
- V = Volume (in units)
Given:
- Magnetization (M) = 5 units
- Volume (V) = 35 units
Calculation Steps
1. Insert the values into the formula:
m = ... more
2. Perform the multiplication:
m = 175 units
Thus, the magnetic moment of the material is 175 units.
Conclusion
The correct answer is option 'D', which is 175. This calculation shows how the magnetic moment is directly influenced by both the magnetization and the volume of the material.
To summarize:
- The magnetic moment quantifies the strength and direction of a magnetic source.
- It is directly proportional to both the magnetization and the volume of the material.
- In this scenario, a magnetization of 5 units in a volume of 35 units results in a magnetic moment of 175 units.
This highlights the importance of both parameters in determining the magnetic properties of materials.

Pallavi Nair answered • Sep 14, 2024 |
To determine the electric field intensity (E) created by a charge (Q) under the influence of a force (F), we can use the relationship given by the formula:
Electric Field Intensity Formula
E = F/Q
Where:
- E = Electric field intensity (in Newtons per Coulomb, N/C)
- F = Force acting on the charge (in Newtons, N)
- Q = Charge (in Coulombs, C)
Given Value... more
- Charge (Q) = 2.5 C
- Force (F) = 3 N
Calculating Electric Field Intensity
Now, substituting the given values into the formula:
E = F/Q = 3 N / 2.5 C
Performing the Division
To calculate:
- E = 3 / 2.5
This can be simplified:
- E = 3 ÷ 2.5 = 1.2 N/C
Reviewing the Options
The options provided were:
- a) -7.5
- b) 7.5
- c) 2.5/3
- d) 3/2.5
Among these options, the value of E we calculated (1.2 N/C) is not explicitly listed. However, option 'd' (3/2.5) simplifies to 1.2, confirming that the correct answer is indeed option 'd'.
Conclusion
Thus, the electric field intensity created by a charge of 2.5 C under a force of 3 N is:
- E = 3/2.5, which is equivalent to 1.2 N/C.
Therefore, option 'd' is correct.

In nanotechnology, the size of the material is reduced to the size of the nano-domain (1 to 100 mm). This dimension is comparable to the wavelength of the photon.
[Statement-I is correct]
Due to the quantum mechanical effect, the motion of randomly moving electrons gets confined to specific energy levels.
It affects the electrical, magnetic, and optical properties of nanomaterials.
[Statement-II is also correct]
Both are independent correct statement
So option (B) is correct.
