FPSC MCQs

The Solar System lies within the Milky Way galaxy.
It is a barred spiral galaxy.

Successive increases are 2, 3, 4, and 5.
Adding 6 to 15 gives 21.

A light-year is a distance unit used in astronomy.
It is about 9.46 trillion kilometers.

Each term is the sum of the previous two.
Thus, 5 + 8 = 13.

Artificial satellites orbit Earth or other bodies.
They support communication, navigation, weather, and research.

Each term is doubled and increased by 1.
So 31 × 2 + 1 = 63.

A receiver compares arrival times from several satellites.
It calculates distance and solves for location and clock error.

Each term is multiplied by 3 and reduced by 1.
Thus, 41 × 3 - 1 = 122.

A modem modulates and demodulates signals for data communication.
Modern devices connect computers or routers to internet services.

The CPU executes program instructions and coordinates operations.
It is often called the processor.

Metamorphism alters rock minerals and texture without complete melting.
Marble forms from limestone.

RAM provides fast working memory for active tasks.
Its contents are usually lost when power is removed.
