Lightening conductors are used to protect building from lightning strikes. Which of the following statements is/are true about lightening conductors? 1) Lightening conductors create an electric field at its top that lightning strikes it preferentially 2) Lightning conductors reduce the effect of the strike by uniformly distributing the charge (current) over the surface of the building 3) Lightning conductors take all the charge (current) to deep down in the earth 4) Lightning conductors must be installed at a place taller than the building Select the correct answer using the code given below
Consider the following statements: 1. Both ferromagnetic and ferrimagnetic materials have domain structures; each domain has randomly oriented magnetic moments when no external field is applied. 2. Both ferromagnetic and ferrimagnetic materials make those domains that have a favourable orientation to the applied field grow in size. 3. The net magnetic moment in ferromagnetic materials is higher than that in ferrimagnetic materials. 4. The net magnetic moment in ferrimagnetic materials is higher than that in ferromagnetic material. Which of the above statements are correct?

Researchers have developed a three-person brain network called BrainNet that lets participants send or receive thoughts from each other. Further, researchers claimed that the network records electrical activity and transcranial magnetic stimulation in the brain, to transmit information without invasion as it can send one bit of a data at a time. Which of the following determines the given statement? I: BrainNet records electrical activity and transcranial magnetic stimulation in the brain. II: BrainNet can send more than one bit of data at a time. III:  BrainNet is a three-person brain network developed to transmit information.
