Bragg's law (Sir W.L. Bragg; 1912)
While a beam of x-rays strikes at crystal surface wherein the layers of atoms or ions are separated regularly, the maximum intensity of the reflected ray takes place while the complement of the angle of incidence, theta, the wavelength of x-rays, lambda, and the distance among layers of atoms or ions, d, are associated by the equation
2 d sin theta = n lambda,
Where n is an integer.
Define Adiabatic Atmospheres (Boston, Maryland)? The lower 10-15 km of the troposphere, the atmosphere, is often in a convective stable state with constant entropy, not constan
Positive rays are sometimes called as the canal waves. These were found by Goldstein. If the cathode of a discharged tube has holes in it and the pressure of the gas is around 10-3
It makes sense that copper should be used because it could heat up faster, making the event more efficient.
what is wedge constraint? explain with example.
Loschmidt constant; Loschmidt number; NL: The number of particles per unit volume of an ideal gas at standard temperature & pressure. It has the value 2.687 19 x 10 25 m -3 .
The energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
How fast would the train be travelling when it in Lac-Mégantic derailed. There were 5 locomotives and 72 cars filled with 113,000 litres of crude oil. The elevation was 520 m Cote
Surface tension can be explained in given possible ways: (i) The property of a liquid on account of which it tends to keep minimum number of molecules in its free surface is d
Q. A rubber ball is dropped to the floor. What force act on the ball to bounce? Does the Earth "bounce" too? Ans. The force of the Earth pushing back on the ball causes
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
