Answer:
The wavelength of the light emitted by a hydrogen atom for the given transition is 2166 nm.
Explanation:
The energy of nth energy levels of the H atom is given as:
Energy of the seventh energy level =
Energy of the seventh energy level =
Energy of the light emitted will be equal to the energy difference of the both levels.
Wavelength corresponding t

Answer;
A. The curl-up only tests the endurance of the abdominal muscles, not their strength
Explanation;
Curl up test measures abdominal strength and endurance. This test focuses predominantly on the main abdominal muscle, the rectus abdominus, and may not evaluate the core as a whole.
This test requires the athlete to complete as many curl-ups as possible at a rate of 20/minute. This test provides a means to monitor the effect of training on the athlete's physical development.
