Answer from: dnjames01

Atoms are mostly empty space with a positively charged core

Explanation:

Ernest Rutherford conducted a series of experiments together with Hans Geiger and Ernest Marsden; in order to corroborate Thomson's raisin pudding atomic model (positive and negative charges evenly distributed, the atom, which is electrically neutral).

However the results of the experiment were surprising an led Rutherford to find out there is a concentration of charge in the atom's core (which was later called nucleus) surrounded by electrons.

This lead to a new atomic model, in which the atom has a positive charged nucleus surrounded by negative charged particles, hence the atom is not electrically neutral.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

Answer from: Quest

Is a vector quantity that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
