Is the stomach because your Large intestine plays a role after the small intestine.
The kinetic energy of a moving object is calculated through the equation,
KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity. Substituting the known values in the problem above,
KE = 0.5(55 kg)(16 m/s)²
KE = 7,040 J
Thus, the kinetic energy of the skydiver is approximately equal to 7 kJ.
1.List one extensive and one intensive property of marker ink.
Intensive property is a property that is independent of the amount of sample such as the color of the ink. Extensive property is the opposite which is dependent to the amount such as volume.
2.Define mixture.
Mixture is a system that contains two or more substances which are agitated but not chemically bonded.
3.Is tap water a heterogeneous or homogenous mixture?
Tap water is a homogenoeus mixture because it has uniform properties in every sample you get.
4.Is isopropyl alcohol (rubbing alcohol) a heterogeneous or homogenous mixture?
I think the rubbing alcohol is a homogeneous mixture since it has uniform properties as well.

Answer:
The correct answer is A) an equal amount of heat will be absorbed by the surroundings.
Explanation:
According to law of conservation of energy or first law of thermodynamics energy can neither be created nor destroyed.Energy can only be converted from one form to another one.The amount of energy of the universe is fixed.
If the reaction have to follow the first law of thermodynamics then according to the question the right answer will be equal amount of heat will be absorbed by the surroundings to maintain the constant energy level of the universe.
