3 The diameter of an atom is about 10-10 m and that of a nucleus is about 10-15 m. Calculate the size of the nucleus or atom in each of the models in the table, and give an example of an object with a size of the same order of magnitude as your calculated size. Object used to Model 'Atom' Object used to 'Nucleus' model the atom object size model the nucleus object size А The Earth 107 m B A classroom 10 m C An apple 10 cm (6 marks)​

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s. what is the wavelength?

Is a volume of space that is empty of matter.
