Ester is any organic compound that has the following generic formula: where R and R 'are radicals, not necessarily equal. Here are some esters: Esterification reaction Esters can be obtained by esterification reaction. A carboxylic acid reacts with an alcohol to form esters and water.
Kepler's Laws (1) One circular orbiting communication satellite has radius R and T period. Another circular orbiting satellite has T / 3 period. What is the radius of the orbit of the second satellite? Universal Gravitation (1) How strong is the earth's gravitational field over the moon? Dice:
As already stated, to get a nuclear plant up and running requires first of all enriched uranium. To give you an idea, 0.5kg of enriched U-235 - the amount used to power submarines and nuclear aircraft carriers - is equivalent to 3.8 million liters of gasoline.
Aka Friedrich Hermann Hund was a German chemist and physicist born on February 4, 1896, in Karlsruhe, Germany. It was he who developed the rule that bears his name, the Hund Rule. He has done important work related to atomic structure and molecules, such as molecular orbitals. He also discovered the Quantum tunneling Principle (barrier in quantum penetration mechanics in spectrography).
When a body performs a Circular Motion, it undergoes an acceleration that is responsible for changing the direction of movement, which we call centripetal acceleration, as seen in the MCU. Knowing that there is an acceleration and given the mass of the body, we can, by Newton's 2nd Law, calculate a force that, like the centripetal acceleration, points to the center of the circular path.
3. A gas cylinder cannot vary the volume of gas inside. If it is taken from an airy environment where the internal pressure is 3 atm and the temperature 15 ° C and is placed under the sun where the temperature is 35 ° C. Assuming the gas is ideal, what will be the pressure after transformation?
