Answer:
We conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.
Thus,
option a) is correct.
Explanation:
When there is no air in the space, it is basically a vacuum.
- In other words, the vacuum can be termed as a 'space devoid of matter'.
So, when there is no air in space, it means there is no force that can act on the body.
- Therefore, no matter what objects (heavy or light) we may drop from the same height, they would all hit the ground at the same time.
As there is no force that can act on an object in the vacuum, it means every object in the vacuum seems to stand still while falling.
Therefore, we conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.
Thus,
option a) is correct.

See the answer below
Explanation:
T<em>he aspect of the event that relates to matter is </em><em>the materials and different shapes of the balls</em><em> while the aspect that relates to energy is t</em><em>he heights reached by the balls as they bounce off the same floor.</em>
Matter is generally defined as any substance that has weight and is able to occupy space. <u>Hence, the balls being made up of different materials and shapes means that they are made up of matter. </u>
Energy, however, is generally defined as the capacity to do work. The more the energy of a system, the more the work that can be done by the system. <u>The height reached by the balls is thus an indication of the amount of energy possessed by the balls.</u>
Answer:
Explanation:
the lose and gain of electron makes the atom an ion it is a charged because it has different number of electron and proton the number of electron differs from the number of proton
Answer:
A hypothesis. In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis. A hypothesis is something more than a wild guess but less than a well-established theory. My hypothesis was right because although it was n educated guess it was still correct
The viscosity value decreased with the increase of temperature. The effect caused by temperature in the range studied was more important in the low range of temperature, whereas at high temperature, the viscosity showed less variation.The studies carried out in the present work indicated that the effect of temperature upon the viscosity of Galician honeys was prominent, and it is necessary to take into account this variable when the operation temperature is under 25°C, since below this value a small variation in temperature produces high changes in the viscosity value. On the other hand, different models to fit experimental values of viscosity/temperature have been proved. The glass transition temperature was determined necessarily since several models include this parameter in the equation, because it provides important information related to the viscosity value. All the models show a good behaviour but the best results were obtained using the Arrhenius one.
