3 days ago · A projectile is an object or body that is shot into the air and allowed to move freely under gravity or on its own. A shot arrow, a thrown javelin, a fired bullet, a kicked football, and so on are examples. Note: Projectile motion has a wide range of applications in physics and engineering. Meteors entering the Earth's atmosphere, fireworks ...

Below are examples that demonstrate the concepts of classes and objects in C++: Example 1: Simple Class and Object. #include <iostream> using namespace std; // Defining a simple class named ‘Rectangle’ class Rectangle {private: int length; int width; public: // Constructor to initialize length and width
4 days ago · Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid ( gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body.
4 days ago · Hint: The thermal motion is the pointless motion of the molecules of the body. This information is key to solve this problem. Complete step by step solution: Thermal motion is the random motion of the micro particles such as atoms, molecules etc. It is different from ordinary mechanical motion because the body moves in all manners.
2 days ago · Whig. Signature. Sir Isaac Newton FRS (25 December 1642 – 20 March 1726/27 [a]) was an English polymath active as a mathematician, physicist, astronomer, alchemist, theologian, and author who was described in his time as a natural philosopher. [7] He was a key figure in the Scientific Revolution and the Enlightenment that followed.
5 days ago · Hint: Drift current is the electric current due to the movement of charge carriers under the impact of an outer electric field, while diffusion current is the electric current due to the distribution of carriers, pointing to a change in carrier collection. Complete answer: Drift current. Diffusion current. 1.
4 days ago · Noether's theorem states that every continuous symmetry of the action of a physical system with conservative forces has a corresponding conservation law. This is the first of two theorems (see Noether's second theorem) proven by mathematician Emmy Noether in 1915 and published in 1918. [1] The action of a physical system is the integral over ...
