Chap 11 - Magnetic Materials.pptxPooja M This document provides information about magnetic materials and concepts. It begins by reviewing magnetic lines of force, why magnetic monopoles do not exist, and what materials are used to make magnetic compass needles. It then discusses the torque on a bar magnet in a magnetic field and two magnets suspended freely and perpendicular to each other. The document explains that the origin of magnetism in materials comes from the electron revolving around the nucleus, which creates a magnetic dipole moment. It also discusses the magnetic moment of an electron and how it is proportional to the orbital angular momentum. Finally, it covers the concepts of magnetization and how it relates to the net magnetic field inside a solenoid.
Chap 11 - ELECTRIC CURRENT THROUGH CONDUCTOR.pptx
Chap 11 - ELECTRIC CURRENT THROUGH CONDUCTOR.pptxPooja M This document discusses electric current through conductors. It begins by defining electric current as the rate of flow of electric charge. In metallic conductors like wires, electric current is carried by the flow of electrons. When a large number of metal atoms come together, their valence electrons become delocalized and free to move throughout the material as conduction electrons.
When a potential difference is applied across a conductor, the conduction electrons begin to drift in the direction of the applied electric field at a constant drift speed. This drift of electrons constitutes an electric current. Ohm's law establishes the direct proportional relationship between current and applied potential difference for many materials when their physical state remains unchanged. The proportionality constant is the resistance of the material.

- Dispersion of light occurs due to the refractive index and wavelength of light. Total internal reflection occurs when light travels from an optically dense medium to a less dense one at an angle greater than the critical angle.
- Reflection and refraction follow specific laws when light interacts with plane and curved surfaces. Multiple images can form when light reflects between two mirrors.
- Refractive index is the ratio of light speeds in different media and determines how much light bends when passing from one medium to another. Optical fibers use total internal reflection to transmit light signals with low loss.

Chapter 3 motion in a plane 
Chapter 3 motion in a plane Pooja M This document discusses motion in two dimensions or motion in a plane. It covers topics like average and instantaneous velocity, acceleration, equations of motion with uniform acceleration, relative velocity, projectile motion, and uniform circular motion. Projectile motion involves calculating the maximum horizontal range of a projectile based on its initial velocity and acceleration due to gravity. Uniform circular motion requires both a tangential velocity and a centripetal force directed toward the center. The period, radius vector, angular speed, and centripetal acceleration are defined for uniform circular motion. Examples of motion in a plane include the trajectory of a projectile and the motion of a conical pendulum.

Lecture 4 INSECT CUTICLE and moulting.pptx
Lecture 4 INSECT CUTICLE and moulting.pptxArshad Shaikh The insect cuticle is a tough, external exoskeleton composed of chitin and proteins, providing protection and support. However, as insects grow, they need to shed this cuticle periodically through a process called moulting. During moulting, a new cuticle is prepared underneath, and the old one is shed, allowing the insect to grow, repair damaged cuticle, and change form. This process is crucial for insect development and growth, enabling them to transition from one stage to another, such as from larva to pupa or adult.

ABSTRACT: I give an introductory discussion of two key philosophical controversies in statistics in relation to today’s "replication crisis" in science: the role of probability, and the nature of evidence, in error-prone inference. I begin with a simple principle: We don’t have evidence for a claim C if little, if anything, has been done that would have found C false (or specifically flawed), even if it is. Along the way, I’ll sprinkle in some autobiographical reflections.
