What does a radio wave do to the charges in the receiving antenna to provide a signal for your car radio? a. Incoming radio wave cause the electrons in the rod to vibrate b. Incoming radio wave cause the annihilation of electrons in the rod c. Incoming radio wave cause the electrons in rod to get ionized d. Incoming radio wave cause the electrons in rod to repel the positive charge
Homework Answers
Answer: (a) Incoming radio wave cause the electrons in the rod to vibrate
Upon incidence, the radio waves that are EM in nature will cause
the charges in the antenna to oscillate with the frequency in which
the waves are travelling. This oscillation will induce an ac
current in phase with the wave frequency in the antenna.

How do neurons conduct information? (Please note: this question refers only to events occurring during the time from the receipt of an external signal by a single neuron to the time this information is relayed to the next neuron or muscle. It does not include anything relating to the initial sensory neuron that stimulated the neuron in question, or the subsequent neuron or muscle that this neuron stimulates.) a. What kind of protein “senses” incoming information at the post-synaptic membrane?...
