Discussion topican enormous amount of electricity is created atpower-generating stations and sent across thecountry through wires that carry high voltages. appliances, power lines, airport and militaryradars, substations, transformers, computers, andother equipment that carries or uses electricity allgenerate electromagnetic fields. many questions have been raised about howelectromagnetic fields affect our bodies. do theypose a public health risk? perform an internetsearch to find information about the effects ofelectromagnetic fields on public health. then, discuss the pros and cons of using equipment thatproduces an electromagnetic field.

Electromagnetic fields cause current to flow through the body to the ground.If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes.

In this way, the electromagnetic fields may affect the public health.

what is the actual question though?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
