What happens to the motion of an object if forces acting on the object are equal and balanced?

A. The object begins to move

B. The object begins to slow down

C. The motion of the object does not change

Answers

Answer:

When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.

So I think its C

You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

How is salinity affected?
(a) evaporation increases
(c) freezing increases
(d) melting increases
(e) precipitation increases

Where does the energy that causes evaporation come from?
What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.

Answers

Answer:

A and E.

Explanation:

 When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the  evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!

     Good luck!

The answer is A hope this helped :)

What patterns in the rock layer fossils helped you identify an extinction?

Answers

Answer:

Hope this helps!! :D

Explanation:

Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

You can often tell by disturbances in the fossils bones. Maybe like dust or particles symbolize harm or mass extinction in a prehistoric animal or maybe even new fossils like some animals that went extinct recently like 200 years.

Answers

directly proportional

Answer:

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.

A: B: C:

Answers

Answer:

A: petal

B:stigma

c: stamen

Explanation:

A flower is considered as a complete one if it has petals, stamen, carpel and sepals. Sometimes pistil is present. Here in the structure part A is Petal, B is Stigma and C is stamen.

What are parts of a flower?

The calyx, corolla, androecium, and gynoecium are found to be the four whorls of a modified leaves which constitute the flower. One of the flower parts in each of the whorl contains sepals, petals, stamens and pistils.

Here A is petal. This part is the bright coloured region which attracts bees and birds. This part help us to differentiate one flower from another. Some petals are dark coloured whereas some other are pale coloured.

Here B is stigma. The stigma is the sticky part of a flower. It is the specially adapted portion of the pistil modified for the reception of pollen. It has a feathery, branched elongated structure.

Here C is stamen - The male reproductive part of a flower is called the stamen. The stamen has long slender stalk called the filament with a two -lobed anther at the tip.

Thus the given parts are petal, stigma and stamen.

Answers

Energy for the light can cause skin cancer and damage genetic materials (melanocytes) however melanin absorbs the light meaning the genetic material in their skin cells are protected from any damage so in conclusion the more melanin in the cells the more their cells are protected

The melanin provides protection against skin cancer by absorbing harmful UV light from the electromagnetic spectrum.

What is electromagnetic spectrum?

The electromagnetic spectrum consists of radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
