It states that if net torque acting on an isolated system is zero, the angular momentum remains conserved. Since Torque is equal to the rate of change of angular momentum so when torque is zero, dL/dt=0 So,...
The polarity of the RodThere is a critical topic in EMI called Motional emf. There is a specific use case where the Rod moves over between the Rails. We know that when this Rod moves in the Perpendicular...
Key points: Friction does not oppose the motion, but it opposes relative movement between the contact surfaces. When there is no relative motion between the contact surfaces, then no friction force...
1) What is an Isotope? Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. 2) What determines the atomic number of an element? A...
We can reduce the corona viral infections by following simple measures or steps. Clean your hands frequently with water, soap and sanitizer (alcohol-based hand rub). This action kills the microorganisms...
