What is the final velocity in free fall? Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 […]
Does TV use microwaves or radio waves?
Does TV use microwaves or radio waves? Microwaves are used because they pass through the atmosphere and through the ionosphere. The signals may be for television programmes, telephone conversations, or monitoring the Earth (for example, weather forecasting). Should I turn off wifi at night? The BEST Way To Shut Off WiFi At Night Safely and […]
What is Biot Savart law and its application?
What is Biot Savart law and its application? The Biot Savart Law states that it is a mathematical expression which illustrates the magnetic field produced by a stable electric current in the particular electromagnetism of physics. This law is applicable in the magnetostatic estimate, & is reliable by both Gauss’s (magnetism) and Ampere’s (circuital) law. […]
How do you classify hydrogen?
How do you classify hydrogen? Hydrogen is most often classified as a nonmetal because it has many of the properties of nonmetals. For example, it is a gas at room temperature. However, hydrogen shares properties with the alkali metals in group 1. In liquid form, hydrogen conducts electricity just like a metal does. Can we […]
What are 3 ways to prevent beach erosion?
What are 3 ways to prevent beach erosion? Since erosion is unavoidable, the problem becomes discovering ways to prevent it. Present beach erosion prevention methods include sand dunes, vegetation, seawalls, sandbags, and sand fences. What happens to a beach when a wave’s backwash is stronger than its swash? If the swash is stronger than the […]
What are the 7 functions of the digestive system?
What are the 7 functions of the digestive system? Digestive System Physiology Ingestion of food. Secretion of fluids and digestive enzymes. Mixing and movement of food and wastes through the body. Digestion of food into smaller pieces. Absorption of nutrients. Excretion of wastes. What organs are part of the digestive system? The hollow organs that […]
What are two recently discovered state of matter?
What are two recently discovered state of matter? The two newly discovered states of matter are Plasma and Bose-Einstein Condensate. Does liquid glass exist? Glass, however, is actually neither a liquid—supercooled or otherwise—nor a solid. It is an amorphous solid—a state somewhere between those two states of matter. And yet glass’s liquidlike properties are not […]

What is quantum number explain with example?
What is quantum number explain with example? A quantum number is a value that is used when describing the energy levels available to atoms and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrödinger wave equation for the hydrogen atom. ms or […]
