now we have




so the ratationa frequency is given by




Animals don't make Their own food. they instead depend on the food made by plants. hence no need for chloroplasts
There are 8 electrons in the third energy level of Calcium atom.
The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
