Analyze the ingredients in ice cream.

Determine how to separate gasoline from other substances in petroleum.

Explanation:

A chemist is a scientist who posses the knowledge of the discipline chemistry. The chemists studies the properties of the chemicals or any other matter present in nature. A chemist can perform testes to identify and quantify substances found miscible in the mixture.

Among the options given, the following are the correct options.

Analyze the ingredients in ice-cream.: The chemist can perform chemical tests to identify and quantify the ingredients present in the ice-cream.

Determine how to separate gasoline from other substances in petroleum.: The petroleum or crude oil can include other volatile substances such as gasoline therefor, suitable chemical extraction processes can be performed to separate such volatile substances.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
