What do viruses inject into cells?
What do viruses inject into cells? During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell’s genetic material and induces it to replicate the viral genome. How do viruses attach […]
What is the change in electric potential energy?
What is the change in electric potential energy? The electron will accelerate toward a higher electric potential due to its negative charge. The change in potential energy is the charge times the potential difference (equation 20-2). The change in potential energy equals the gain in kinetic energy, which can then be used to find the […]

Which metal is used in wires?
Which metal is used in wires? Copper Which wire can carry a higher current? Answer. “In solid wire of same length resistance of that wire is higher than stranded wire”. Hence stranded wire carries more current than solid wire due to lower resistance. Thus due to extra surface area more surface current flows Therefore in […]
