Dynamo - Galileo

This is the incorrect match because Galileo did not invent or develop the dynamo. The dynamo was actually invented by Michael Faraday in the early 19th century.

Explanation:

1. Jet Engine - Whittle:
The correct match is (a) Jet Engine - Whittle. Sir Frank Whittle, a British inventor and engineer, is credited with inventing the jet engine. He developed the concept of a jet propulsion system in the 1920s and successfully built the first operational jet engine in the 1930s.

2. Gravity - Newton:
The correct match is (b) Gravity - Newton. Sir Isaac Newton, a renowned physicist, is famously known for his laws of motion and the law of universal gravitation. He formulated the law of gravity, which explains the force of attraction between objects with mass.

3. Dynamo - Galileo:
The incorrect match is (c) Dynamo - Galileo. Galileo Galilei, an Italian scientist, astronomer, and physicist, did not invent or develop the dynamo. The dynamo, which is a device that converts mechanical energy into electrical energy, was actually invented by Michael Faraday, an English scientist, in the early 19th century.

4. Diesel Engine - Rudolf Diesel:
The correct match is (d) Diesel Engine - Rudolf Diesel. Rudolf Diesel, a German inventor, is credited with inventing the diesel engine. He developed the concept of a compression-ignition engine, which became known as the diesel engine. Diesel engines are widely used in various industries and transportation systems.

In conclusion, the incorrect match in this question is (c) Dynamo - Galileo, as Galileo Galilei did not invent or develop the dynamo. The correct inventor of the dynamo is Michael Faraday.
