Answer:

J J Thomson

Explanation:

J J Thomson in the year 1898 was the one who proposed the  model of the atom that described electrons scattered throughout a ball of positive charge. This was the first atomic model , he proposed that atom is like a sphere with radius 10^{-10} m , where the positive charge is uniformly distributed. The electrons are embedded into it so as to give the most stable electrostatic arrangement.

If a simple machine reduces the strength of a force, what must be increased?
rodikova [14]

Answer:

Option D

Explanation:

The answer is option D or "the distance over which the force is applied." Since basic machinery is created to lessen the work for us humans reducing the strength of the force means that the distance which where the force is needed to be applied needs to be increased. Increasing the distance for the machine makes it all around more efficient. One of the most common examples of basic machinery is a rake. When using a rake, you do not need to apply as much force into it to make the rake efficient. If you increase the distance on where you are raking, then the amount you are raking increases, which means it's all-around efficiency increases.

Hope this helps.
