Which instrument is used for measuring mass

Solids will usually sink when placed in their own liquids. Which is an exception?

WATER

Solids will usually sink when placed in their own liquids with the exception of water

Explanation:

Ice (the solid form of water) floats on water that is cooler than 4 degrees centigrade. This is unlike any other material and this phenomenon has been referred to as the ‘water anomaly’.

Most substances will sink in their own liquid because the solid form is denser than the amount of their own liquid that they displace when immersed. This is because the particles in the solid are closely packed together hence there are more particles per volume than in the liquid form.

Water however, expands at temperatures below 4 degrees and hence ice is less dense than water at 4 degrees and below. The particles in ice are farther apart than particles of water at 4 degrees and below. There is, therefore, more particles per volume in the liquid form of water than in ice – making ice less dense.

A student crested a model to show the flow of energy in a terrestrial ecosystem.

mario62 [17]

Answer:

In an ecosystem, energy enters in the form of solar energy or light energy from sun. Solar energy is transformed into various other types of energies like kinetic energy, chemical energy, potential energy, etc; but it eventually leaves the ecosystem in the form of heat energy.

What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct
