Consider the following statements:

1. Jet engines can be used to propel vehicles into outer space.

2. Jet engine draws air for combustion from the atmosphere.

Which of the above statements is/are correct?

1 only

2 only

Both 1 and 2

None of the above

Explanation:

1st statement is incorrect.
The engine in a jet aeroplane works on the same principle as a rocket but there is a difference in the method of obtaining the high velocity gas jet. The fuel used in a jet engine is Kerosene (paraffin). While rockets carry their own oxygen supply, jet engines draw air out of the atmosphere. Therefore, jet engines cannot be used to propel vehicles into other space where there is no atmosphere.
