4. What is the de Broglie wavelength of a 1375 kg car traveling at 43km/h

Which particle tells you which element you are? Proton Neutron Quark Electron

rather than series circuits? because in a series circuit, all devices must be turned on in order for current to flow because too much wire would be needed for a series circuit for an entire building because in a series circuit, if you turn on one device, all of the devices turn on because power plants generate electricity that can only flow in parallel circuits Why are parallel circuits used in the wiring of houses and other buildings, 2 point
