Answer:
Copper and Silver are both malleable and ductile
12. A malleable sheet of metal used to wrap food in the kitchen is made of only aluminum. What can be said about the metal sheet?
Answer:
is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.[1] In the United States, foils are commonly measured in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. Aluminium foil supplanted tin foil in the mid 20th century.

All surfaces have texture, which means it affects how things move over it. When it takes a long time for friction to slow down an object, what is most likely true about the surface the object is moving on? The surface is dry. The surface is rough. The surface is uneven. The surface is smooth.
The question is incomplete, the complete question is;
All surfaces have texture, which means it affects how things move over it. When it takes a long time for friction to slow down and object, what is MOST LIKELY true about the surface the object is moving on? (A) The surface is dry (B) The surface is rough (C) The surface is uneven (D) The surface is smooth
Answer:
(D) The surface is smooth
Explanation:
Friction exists because of relative motion between two surfaces in contact with each other. However the magnitude of friction depends on how rough or smooth the surface is.
For smooth surfaces, there is little or no resistance to motion as objects move over the surface. Hence objects take a longer time to slow down on a smooth surface due to very little friction.
On a rough surface, objects tend to slow down relatively quickly. Hence, less resistance to motion on a smooth surface makes an object to take a longer time to slow down on a smooth surface than on a rough surface.
Answer: D
Explanation: Because if the surface is smooth it causes it to be more even for it to be able to cause Friction

If a compound is made up of more than one element why is it considered a pure substance? Choose 2 Group of answer choices The compound has different properties than the individual elements A compound can not be physically separated A compound can not be chemically separated A compound can be physically and chemically separated
Answer:
A compound can not be physically separated
Explanation:
A compound is a chemical substance that comprises of atoms of more than one element i.e. two or more elements are chemically combined to form a compound. However, as stated in this question, compounds are referred to as pure substances.
This reason is attributed to the fact that a compound cannot be physically separated i.e. the constituents of a compound cannot be separated using physical changes or methods. This is because the atoms of the constituent elements are combined or joined together by chemical bonds.
Answer:
Even though a compound can be made of two or more types of atoms, it is still a pure substance because the compound can be isolated, like salt or water.

Temperature is a measure of the average _____energy of particles in a substance.
Answer:
kinetic energy
Explanation:
Answer:
kinetic energy
Explanation:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

I WILL MARK BRAINLIST TO WHOEVER SHOWS FULL STEPS PLEASE LOOK AT THE IMAGE ABOVE
Answer:
+47°C
Explanation:
ΔT means change in temperature. If the change is positive, it means that heat was added and the temperature went up.
ΔT = final temp - initial temp
ΔT = 86°C -39°C = + 47°C
Describe the difference between balanced forces and unbalanced forces.
Answer:
If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

The characteristic bright–line spectrum of potassium is produced when electrons
A) jump to higher energy levels
B) return to lower energy levels
C) are lost by neutral potassium atoms
D) are gained by neutral potassium atoms
E) are released from the nucleus
Answer: B.
Explanation:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

With circulation, the heart provides your body with:
a. oxygen
b. nutrients
C. a way to get rid of waste
d. all of the above
Explanation:
The lungs pump oxygen in and carbon dioxide out, which goes through the blood stream to help with the cell's energy needs.
Nutrients pass through the blood stream as well. The nutrients start with the digestive system (mouth, esophagus, stomach, small intestine) before going into the blood stream. The nutrients are building blocks to help make new cells when old ones die off.
When those cells die off, the body sheds them like dead skin, but internal dead cells are passed off as waste. This waste and other byproducts the body doesn't need passes through the blood stream as well.
In short, the blood stream is basically the highway to help get desired materials (eg: oxygen and nutrients) and get rid of waste (eg: carbon dioxide and other unwanted byproducts or dead cell material)
So that's why the answer includes A, B and C.

Is it possible for a rock to be shaped by forces in the Earth. This picture could be described as a/an
Answer: Yes
Explanation:
Different force on earth such as wind ocean currents etc make the rocks in earth crests to be change in their shape and size and they moves to different plates.
What is rock cycle?Rock cycle is the process by which rocks are transforming from one type to the other by the action of wind, water etc.The land is eroded and shaped by wind, water, and ice.
The landscape is dramatically and frequently violently altered by volcanic activity and earthquakes. And over a much longer period of time, the shifting of the earth's plates gradually rearranges the continents and oceans.
These mechanisms all have an impact on the Arctic and Antarctica. We'll go through each in general and in relation to the polar areas specifically.
The three main causes of erosion, or the carrying away of rock, silt, and soil, are wind, water, and ice. Weathering, or the physical or chemical degradation of the minerals in rock, is separated from erosion.
