Demonstrating how the angle of the sun's rays changes from day to day at the same hour
Cut a 1-cm round hole in a piece of paper or cardboard. Place this in a south window of your classroom where the sun's rays will shine by the hole and strike a piece of white paper on the floor, the table or window sill. Draw the outline of the spot where the beam of light strikes the paper. Write the date and hour inside the outline. Repeat this on succeeding days at exactly the similar hour
Elastic collision : A collision is known as elastic when kinetic energy is also conserved along with the linear momentum. There is no transformation or loss of kinetic energy in th
"The volume of needed mass of gas at fixed pressure is directly proportional to the Kelvin's temperature of the gas".
#questionMnS is a paramagnetic solid. At 300°K, there are 4 × 1022 molecules of MnS per cm3. If the cationic magnetic moment of MnS is 5 MB, use the Curie law in 8-b to compute the
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this te

What is the difference between an adiabatic and an isoperibol bomb calorimeter?
When are intermolecular forces the strongest? Intermolecular forces (dipole-dipole, dispersion and hydrogen bonds). These forces are weaker than chemical (covalent) bonds. Thus
