Using the Rydberg formula, the spectral line of H - atom is suitable for this purpose is Paschen, ∞ → 3.
- Using the Rydberg formula;
1/λ = RH(1/nf^2 - 1/ni^2)
Given that;
λ = wavelength
RH = Rydberg constant
nf = final state
ni = initial state
- When final state = 3 and initial state = ∞
Then;
1/λ = 1 × 10^7 m-1 (1/3^2 - 1/ ∞^2)
1/λ = 1 × 10^7 m-1 (1/3^2 )
λ = 900 nm
Hence, the correct answer is Paschen, ∞ → 3

Explanation:
Newton's second law states the "net force on a body is the product of its mass and acceleration".
When a body has a net force acting on it, it will change position and begin to move.
Ordinarily, a car will not move until it is towed when the engine is faulty. The weight of the car and the frictional force of the tire acts to prevent its motion.
Now, the towing van supplies a force that is greater than the weight of the car and the frictional force between the tires. This way the towing van is able to move the faulty car.

The answer is C
Explanation:
Thomson conducted many tests with cathode rays. Which led to his discovery of the electron.
Answer:
Phase changes typically occur when the temperature or pressure of a system is altered. When temperature or pressure increases, molecules interact more with each other. When pressure increases or temperature decreases, it's easier for atoms and molecules to settle into a more rigid structure.
