What is energy of electron in Nth Orbit? Energy of the electron in `nth` orbit of hydrogen atom is given by `E_(n) =-(13.6)/(n^(2))eV`. What is the radius of nth orbit in hydrogen atom? So, radius of nth orbit is rn=rn2, as Z=1 for H atom. What is the radius of the first orbit of hydrogen […]
What is primitive data type with example?
What is primitive data type with example? Primitive data types – includes byte , short , int , long , float , double , boolean and char. Non-primitive data types – such as String, Arrays and Classes (you will learn more about these in a later chapter) Why are they called primitive data types? Primitive […]
What are the 7 biological processes?
What are the 7 biological processes? There are seven essential processes in common: movement, respiration, sensitivity, growth, reproduction, excretion and nutrition or MRS GREN. How does the biological process work? Biological processes are made up of many chemical reactions or other events that result in chemical transformation. Metabolism and homeostasis are examples. Regulation of biological […]
What layer is called the true skin?
What is the weight of a 10 kg object?
How heavy is gold underwater?
How heavy is gold underwater? 10.80 kilos What’s at the bottom of quicksand? Quicksand usually consists of sand or clay and salt that’s become waterlogged, often in river deltas. The ground looks solid, but when you step on it the sand begins to liquefy. But then the water and sand separate, leaving a layer of […]
What are the two main types of satellites?
What are the two main types of satellites? There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around […]
What would happen if there was no air resistance?
What would happen if there was no air resistance? If there is no air resistance, after you let go of an object the only force on it is the gravitational force. More massive objects have a greater gravitational force. The acceleration of an object is proportional to the net force on the object and inversely […]
How long does it take for a star to go supernova?
