What are ferromagnetic and antiferromagnetic materials? Ferromagnetic materials have magnetic moments that align parallel to the applied magnetic field whereas antiferromagnetic materials have antiparallel magnetic moments. Therefore the magnetic moments still cancel each other out and the overall magnetization is zero. What is hysteresis loop explain with diagram? A hysteresis loop shows the relationship between […]
Why is it called a diverging lens?
What is ab initio method in physics?
What is ab initio method in physics? In nuclear physics, ab initio methods seek to describe the atomic nucleus from the bottom up by solving the non-relativistic Schrödinger equation for all constituent nucleons and the forces between them. A significant challenge in the ab initio treatment stems from the complexities of the inter-nucleon interaction. What […]

How does the nucleus change in beta decay?
How does the nucleus change in beta decay? A beta results in a neutron emitting a high energy electron and becoming a positive proton. Beta decay changes the atomic number of the nucleus by increasing the number of protons, by decreasing the number of neutrons while leaving the atomic mass essentially the same. What does […]
What is called critical angle?
What is called critical angle? When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. Why […]
What are 3 features of karst topography?
What are 3 features of karst topography? Karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone. What are karst landscapes used for? Karst environments in New South Wales were among the […]
Can you have a growth spurt at 16?
Why is resistance less when resistors are joined in parallel?
Why is resistance less when resistors are joined in parallel? When resistances are connected in parallel the current in the circuit gets parallel branches to go from one point to another across which the potential difference is applied. So, the equivalent resistance is less when resistors are connected in parallel. What happens to resistance in […]
How will chemistry help us in the future?
How will chemistry help us in the future? Research is constantly deepening our understanding of chemistry, and leading to new discoveries. Chemistry will help us solve many future problems, including sustainable energy and food production, managing our environment, providing safe drinking water and promoting human and environmental health. What is the role of chemistry in […]
