- A. Kirkpatrick Macmillan
- B. Alessandro Volta
- C. Leo H Baekeland
- D. Frank Whittle
Remarks:
Explanation:
Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800. This was a stack of copper and zinc plates, separated by brine-soaked paper disks, that could produce a steady current for a considerable length of time. Volta did not understand that the voltage was due to chemical reactions. He thought that his cells were an inexhaustible source of energy and that the associated corrosion effects at the electrodes were a mere nuisance, rather than an unavoidable consequence of their operation, as Michael Faraday showed in 1834.
- A. James Hargreaves
- B. Frank Whittle
- C. Evangelista Torricelli
- D. None
Remarks:
Explanation:
Air Commodore Sir Frank Whittle (1 June 1907 - 9 August 1996) was an English Royal Air Force (RAF) engineer air officer. He is credited with single-handedly inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention; however, this was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Hans von Ohain who was the designer of the first operational turbojet engine.
- A. Benjamin Franklin
- B. Sir William Grove
- C. Albert Einstein
- D. Alfred Nobel
Remarks:
Explanation:
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht and patented in 1867. It rapidly gained wide-scale use as a safer alternative to black powder.
Today dynamite is mainly used in the mining, quarrying, construction, and demolition industries. Dynamite is still the product of choice for trenching applications, and as a cost-effective alternative to cast boosters. Dynamite is occasionally used as an initiator or booster for AN and ANFO explosive charges.
