Question

HI CAN SOMEONE HELP ME WITH THIS 2 QUESHTIONS PLEASE ITS URGENTLY I DONT UNDER STAND THEM.!!!!!!! my school school closed and I need help rapidly

1. Physicists are conducting experiments to determine if quarks are the fundamental building blocks of atoms. This is an example of:

applied research.

basic research.

natural speculation.

medical technology.

2. A mixture of salt, iron, and sand can be separated using a magnet, water, and a filter. The separation of this mixture:

uses physical processes only.

uses chemical processes only.

uses both chemical and physical processes.

cannot be done with the materials listed.

Answer 1

1. PHYSICIST ARE CONDUCTING EXPERIMENTS TO DETERMINE IF QUARKS ARE THE FUNDAMENTAL BUILDING BLOCKS OF ATOM. THIS IS AN EXAMPLE OF

APPLIED RESERCH BECUASE( QUUARKS COMBINE TO FORM THE BASIC BUILDING BLOCK OF MATTER ,BARYONS AND MESONS.BARYONS ARE MADE OF THREE QUARKS TO FORM THE PROTONS AND NEUTRON OF ATOMIC NUCLEI.MESONS MADE OF QUARK PAIRS, ARE USUALLY FOUND IN COSMIC RAY. IT IS NOT RELATED TO MEDICAL TECHNOLOGY).  

2. A MIXTURE OF SALT , IRON , AND SAND CAN BE SEPARATED USING A MAGNET, WATER , AND A FILTER . THE SEPARATION OF THIS MIXTURE - USES PHYSICAL PROCESS ONLY.( THE UNDERLYING MESSAGE OF THAT THE PHYSICAL PROPERTIES OF THE COMPONENT OF A MIXTURE CAN BE USED TO SEPERATE THEM FORM MIXTURE. THIS IS SIMPLE BUT IMPORTANT CONCEPT THAT WE USE IN MANY CHEMICAL ANALYSIS AND SYNTHESIS THE CHNIQUES.)
