Answer:
Given that a negatively charged rod is brought closer to two metal spheres which are in contact with each other as shown: So, free electrons from rod will be attracted towards the metal spheres.
The correct answers are:
• The solar wind produces the northern and southern lights
• The solar wind disrupts communication systems.
• The solar wind distorts Earth's magnetic field.
Solar winds are geomagnetic stream of charged particles radiated from the outer atmosphere of the sun. All planets are protected from solar winds via magnetic fields but planets that are positioned closer to the sun can experience degeneration of the magnetic field.
Solar winds are capable to distort and even destroy the functioning of communication satellites in outer space, such as radio and tv communication and satellite based internet services.
The effects of solar winds that are visible to naked eye are the Aurora Borealis (the Northern lights) and the Aurora Australis (the Southern Lights).
<span>A fossil leaf that is made only of carbon preserved between two rock layers is called carbon film fossil.
</span>Characteristic of the carbon film fossils is that they are primarily composed of carbon. The fossil leaf has usually lost <span>internal components (cell walls and internal cell structures ).</span>
<span>The cell has 1% concentration of the salt. The external environment is highly concentrated with 25% saline solution. This will lead to release of water outside the cell, by passive diffusion from a region of high conentration of solvent to lower concentration. Thus, the cell will shrink.</span>
