A refracting telescope is a type of optical telescope that uses a lens as its objective to form an image.
Astronomers use a telescope to observe distant things. Curved mirrors are used by the majority of telescopes, including all large telescopes, to collect and concentrate light from the night sky.
Refracting telescopes have been used for centuries and are still commonly used today, especially for viewing bright objects such as the Moon and planets.
However, they have some limitations compared to other types of telescopes, such as difficulty in making large lenses without distortion and the tendency to produce chromatic aberration, which can cause images to appear blurred or discolored.
Despite these limitations, refracting telescopes remain popular among amateur astronomers and are still used in many scientific applications.

Rutherford's experiment conclude that: atoms are not solid, atoms are hollow and most of the space is vacuum and the positive charge in an atom is not spread evenly .
Rutherford's observations lead him to draw the following conclusions:

Rutherford's model of the atom (ESAAQ) Rutherford carried out some experiments which led to a change in ideas around the atom. His new model described the atom as a tiny, dense, positively charged core called a nucleus surrounded by lighter, negatively charged electrons.
Power in physics is the rate of energy transferred per unit time. It can be calculated by dividing the amount of energy transferred by the time required for the transfer.
In Physics, power is defined as the rate of transferring energy or the amount of energy per unit time. If you want to calculate the power, you take the amount of energy transferred and divide it by the time it takes for that transfer to occur. For example, if a light bulb transfers 100 joules of energy over 10 seconds, the power would be 100 joules divided by 10 seconds, which equals to 10 watts.
