Answer 1

(i) The most dangerous part of fallout comes from - (d) fission fragments.

Because enormus amount of energy releases in fission reaction.

(ii) The linear hypothesis relates to - (b) radiation illness.

(iii) Moore's law concerns - (a) Computers.

Moore's law is the observation that the no. of transistors in a dense integrated circuit doubles approximately every two years. Therefore, it tells about electronic equipment.

(iv) - (a) it has sufficient velocity to escape gravity.
