A. To make the negatively charged particles attract to something else than the other sphere, then do A.
Explanation:
According to the forces of attraction,the student should place a negatively charged rod near the left sphere.
What are forces of attraction?Forces of attraction is defined a force by which atoms present in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart from each other . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

(GIVING BRAINLYLIST) Describe an adaptation to a plant's physical characteristic and explain how this adaptation helps the plant survive.
Answers
Answer:
Plant adaptations are changes that help a plant species survive in its environment. Aquatic plants that live underwater have leaves with large air pockets inside that allow the plant to absorb oxygen from the water. The leaves of aquatic plants are also very soft to allow the plant to move with the waves.

Grassland
Rainforest
Tundra
Wetland
Answers
Answer:
The answer would be tundra.
A rain forest has a lot of humidity because it rains a lot otherwise it wouldn't be called a rain forest.
Grassland has a somewhat high temperature and average humidity enough to keep it green and grassy hence grasslands.
A wetland has a lot of water but low temperatures. Still, humidity is water so wetlands aren't it.

In addition to changing the symbol to C, how would this diagram compare with an electron dot diagram of a carbon atom (C)? The dot to the left of the symbol would be removed in the diagram for carbon. The same number of dots would appear in the diagram for carbon. There would be two dots above and to the right of the symbol in the diagram for carbon. The single dots would be replaced with two dots on each side of the symbol in the diagram for carbon

What is the lewis electron dot diagram?A lewis electron dot structure of an element or molecule can be used to represent the number of bonds, the bonded atoms, and the lone pairs remaining in the atoms in the molecule.
Lines can be used to show between atoms that are bonded with each other and excess electrons can be represented as dot pairs and denoted in front of the atoms.
The valence electrons of each carbon atom are equal to four from the electronic configuration of the carbon atom. As the valence electrons of each Silicon atom are equal to four from the electronic configuration of the silicon atom.
Both silicon and carbon belong to the same group so they have the same number of valence electrons. Therefore, the same number of dots will appear in the electron dot diagram for carbon.

HElphow can an electrical current produce a magnetic field, and how can a magnetic field produce an electrical current? explain
Answers
Answer:
As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
Explanation:
Answer:
What is Electric current?
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge past a region.
What is a Magnetic Field?
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials.
How can an electrical current produce a magnetic field?
These circles stretch out along the wire, forming cylinders. If an electric current is passed through a long coil of wire (a solenoid ) a magnetic field is produced which is the same shape as that of a bar magnet.
How can a magnetic field produce an electrical current?
Moving magnetic fields pull and push electrons. ... Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.

Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.

An example of the transfer of energy between systems through work is the expansion of gas in a steam engine or car piston. Explain the energy transfer process.
A) Steam engines and pistons both expand as pressure is exerted within them and they go on to accomplish work like moving a train.
B) Energy is converted to work as the expansion of the steam engine occurs and the gas collides with the internal steam engine parts.
C) The rapidly moving particles of the expanding gas is doing work on the piston and energy is transferred from the gas to the piston.
D) The quick moving parts of the expanding steam engine is doing work on the piston and energy is transferred from the engine to the piston.
Answers
Answer:
C is the answer because since it's chemistry particles expanding would most likely be your answer
The energy transfer process is rapidly moving gas particles which are expanding doing work on piston and energy transferred from gas to piston according to first law of thermodynamics.
What is first law of thermodynamics?First law of thermodynamics is related to law of conservation of energy along with distinguishing between transfer of energy.According to this law, total energy of an isolated system remains constant.
It only gets transformed from one form to another.It puts in action the flow of energy across boundaries separating system from its surroundings.
Classic example of first law of thermodynamics is steam engine .It operates in a cyclic fashion with piston moving up and down with each cycle.Steam is fed into cylinder in first half of cycle and for second half of cycle it is allowed to escape. Work done in one complete cycle,is the difference between absorption of heat at high temperature and it's exhaustion at lower temperature.
