Answer:

International date line would represent by 180 longitude

Explanation:

An "imaginary line of demarcation" on the earth’s surface that runs from the south pole to the north pole. It demarcates the one-day calendar change to the next. Through the centre of the pacific ocean, it passes with 180-degree longitude and halfway through the world from the Greenwich meridian.

Though in many cases the imaginary line of demarcation follows 180-degree meridian exactly. And at other places, the imaginary line of demarcation deviates east or west through the apex.

Which statement is TRUE regarding the macroscopic and

damaskus [11]

Answer:

Chemists make observations on the macroscopic a scale that lead to conclusions about microscopic features

Explanation:

Many important chemical observations are made on the macroscopic scale. This is because, many of the scientific equipments available are not presently able to provide direct evidence about microscopic processes. Evidences obtained from macroscopic observations could serve as important insights into the nature of certain microscopic processes.

This is evident in the study of the structure of the atom. Most of the evidences that led to the deduction of the atomic structure were obtained from macroscopic evidence but ultimately provided important information about the microscopic structure of the atom.

lyudmila [28]

Answer:

The returns of the company as it is given is already large that is 91% and to get an outcome even better is what it is getting now. There should be certain improvements that needs to be applied with the help of stoichiometric data gathered.

Explanation:

Since the cost of materials cannot be affected and have to be bought under similar rate of cost of working or process can be decreased. By using machines calculation and mechanical devices this come would be accurate and the laws would be minimised. Hence the companies outcome would increase.

Which statement best describes what happens when oil and water are stirred together? (1 point)

Charra [1.4K]

When oil and water are stirred together, water molecules will attract each other electrically, but they will not attract oil molecules, causing separation.

Water is a polar molecule while oil is a non-polar molecule. Water can only dissolve polar molecules and hence, oil is insoluble in water.

When water comes in contact with oil, water molecules attract each other, while the oil molecules stick together, hence, forming two separate layers of water and oil. The oil layer floats on the water layer.

Therefore, when oil and water are stirred together, water molecules will attract each other electrically, but they will not attract oil molecules, causing separation.
