A system that can be affected by the outside environment, by an exchange of matter or energy is an open physical system .
Option (b) is correct.The index of refraction for the glass is 1.52
Explanation:
velocity of light in vacuum= C= 2.99 x 10⁸m/s
Velocity of light in glass = V= 1.97 x 10⁸m/s
The refractive index is given by n=
n= 2.99 x 10⁸/1.97 x 10⁸m/s
n= 1.52
Thus the refractive index of glass is 1.52
The kinetic energy of any moving object is
(1/2) (mass) (speed²) .
For the object you described, that's
(1/2) (100 kg) (12.5 m/s)²
= (50 kg) (156.25 m²/s²)
= 7,812.5 joules

Answer: during which process is water produced
Explanation: Water is produced when electron transport chain
Side effects can be bad skin because nutrients do not get properly absorbed (if we're talking about bulimia or anorexia nervosa). Furthermore, such a person can seem to have lost a lot of weight in a short period of time.
Another thing one can notice is that they are reluctant to eat food in company and have a problem with doing so.
