Answer:
Position
Explanation:
Motion is a change in position.
Answer:
exactly 5.88 J
Explanation:
Let's calculate the initial total mechanical energy of the vase when it starts its fall, from a height of 0.750 m. At that moment, the vase does not have kinetic energy, but only potential energy. So, its total mechanical energy is given by:
When the vase falls and reach the position at 0.500 m, part of this energy has been converted into kinetic energy, However, the total mechanical energy is constant, because there are no frictional effects: therefore, the total mechanical energy at 0.500 m above the floor is still equal to the initial total mechanical energy, 5.88 J.
Answer:hello what are we to do
Explanation:
Yes water is liquid.
Explanation: At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second.
Explanation:
Pure substances are typically elements and compound with the following characteristics:
- Pure substances are distinct substances.
- They are homogeneous in all their parts i.e they are the same all through.
- They have a definite composition
- They cannot easily be separated or broken down into simpler substances by physical means.
- Separation by physical means is not easy
- They have a unique sets of physical properties
Impure substances are mixtures. They have the following features:
- Their composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass.
- Constituents retain their identities i.e physical properties are retained.
- The constituents reacts differently to changed conditions.
- They can easily be separated into their constituents by physical methods.
