(NO LINKS) Compare and contrast magnetism and electricity. And how are they alike? No need for a long answer.

Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field.

Explanation:

Explanation:

Magnitisim is caused by a moving electric field, and electricity can be caused by a moving magnetic feild.

i would like to breefly explain how light is a product of these two fields.

Say you have an electricly charged particle. lets prettend it has a +electric field. Lets shake it up and down in a periodic way. So now the electric field is moving perpendicular to the motion of the particle. But the electric field has to turn into a magnetic field becuase its moving. and it does. but the the same happins with the magnetic feild becuase its moving. and it goes back and forth and gives rise to light

real, smaller and upside-down.   so the answer should be b.

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.
