Explanation:
A. answer is the correct answer
Answer:
Explanation:
From A to B
distance traveled with velocity
in time
from B to C
distance traveled is 0.5 d with
and
velocity for half-half time
divide 1 and 2 we get
Now average velocity is given by
taking
common
Explanation:
It is given that,
Wavelength of a beam of light in vacuum, 
(a) Let v is the speed of light in a liquid whose index of refraction at this wavelength is 1.56.
We know that,
Refractive index,

(b) The wavelength of light in material,

Let
is the wavelength of these waves in the liquid. So,

Hence, this is the required solution.
Answer:
B. Strength
Explanation:
The OPT Model, or Optimum Performance Training Model, is a "fitness training system created by the NASM. The OPT Model is contructed with scientific evidence and principles that progresses an individual through five training phases: stabilization endurance, strength endurance, hypertrophy, maximal strength and power".
On the stabilization level we have the phase 1 called stabilization endurance.
For the level strength part we have 3 phases . Phase 2: Strength endurance , Phase 3: Hypertrophy, Phase 4: Maximal strength. And we can consider the case "A seated cable row" on this the level strength since we need to have some abilities to do this but not enough to stay on the power level since this one is the advancd level.
For the power level we have the last phase called power in order to mantain and conduct high training level programs.
