In some unusual applications of unusual components, I can think of unusual electric circuits where a switch may be connected in parallel with a device in order to control it.
But I'm sure this is not what's intended in a question on the high-school level.
Until you get in a situation with tricky applications in a tricky circuit, your switches will always be connect <em>in series</em> with the devices they control.
Use of electromagnetic because it moves very faster than others for example xrays theynar very very slow so that not It it is d.
Uhm, i'm pretty sure it's deadly.
momentum(p) = mass(m) x velocity(v)
KE = kinetic energy = 1/2 mv²
a.
the ratio of the momentum of the SUV to that of the car

b. the ratio of the KE of the SUV to that of the car

I think if the temperature increased there would be waves, you know?
I hope this helps you.
