And both discovered electromagnetic induction. this is that electric current could be produced in a wire by moving a magnet in or out of a coil of wire.

Michael Faraday  & Joseph Henry

Explanation:

Michael Faraday  & Joseph Henry both discovered Electromagnetic induction Working independently in Britain and United states respectively.Both discover that  current could be induced in a wire by moving a magnet in or out of a coil of wire.Henry develop the electromagnet in a practical device and laid the foundation of Electrical telegraph invented by Samuel F. B. Morse and Sir Charles Wheatstone, separately.

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
