If the amplitude of a simple harmonic motion is doubled, the total energy becomes
The total energy (E) in Simple Harmonic Motion (SHM) is expressed as: E = (1/2) k A² where: - k is the force constant, - A is the amplitude. Because energy is proportional to A², if the amplitude A is doubled (2A), the total energy becomes: E' = (1/2) k (2A)² = 4 × (1/2) k A² = 4E So, the total enerRead more
The total energy (E) in Simple Harmonic Motion (SHM) is expressed as:
E = (1/2) k A²
where:
– k is the force constant,
– A is the amplitude.
Because energy is proportional to A², if the amplitude A is doubled (2A), the total energy becomes:
E’ = (1/2) k (2A)² = 4 × (1/2) k A² = 4E
So, the total energy becomes four times its initial value.

The correct answer is: (c) River Indus to River Brahmaputra
Explanation: The Himalayan mountain range is covered by major rivers that flow from west to east. The two prominent rivers marking the western and eastern extents of the Himalayas are: Indus River (West) – Originates in Tibet near Lake Mansarovar, flows through Ladakh, Pakistan, and into the Arabian Sea. Brahmaputra River (East) – Also originates in Tibet (as the Tsangpo), enters India through Arunachal Pradesh, and flows through Assam and Bangladesh before joining the Bay of Bengal.
