An acorn with a mass of .0300 kilograms is hanging from a branch in a tree. It is 2.50 meters from the ground. What is the potential energy of the acorn?

Answers

The answer is 0.74 J.

The potential energy of the object is its stored energy. Gravitational potential energy is the stored energy of the object as the result of its height can be expressed as:
E = m · g · h
where
E - the potential energy of the object,
m - the mass of the object,
g - gravitational acceleration (g = 9.81 m/s²),
h - the height of the object.

It is given:
g = 9.81 m/s²
m = 0.03 kg
h = 2.5 m

Therefore:
E = m · g · h
⇒ E = 0.03 kg · 9.81 m/s² · 2.5 m
⇒ E = 0.03 · 9.81 · 2.5 kg ·m/s² · m
⇒ E = 0.74 kg ·m²/s²
⇒ E = 0.74 J

Therefore, the potential energy of the acorn is 0.74 J.

The amount of water a body requires for survival is dependent upon the climate and individuals level of physical activity

Answers

The recommendation of health professionals is to drink 8-10 glasses of water daily. But this is dependent on the climate and the activity the person is engaged into. For instance, an athlete who is training needs to drink more water to replace all the water lost in his body during training than compared to a person not training or exercising.

What happens if you place human red blood cells in a concentrated salt solutiona. They shrink as water moves from inside to outside the cells as a result of osmosis
b. They burst as one to move from outside to inside the cells as a result of osmosis
c. No change occurs as water freely diffuses back-and-forth across the cells membrane
d. DeSales expand energy pumping water out in response to the great external salt concentration

Answers

Answer:

The correct answer would be a. They shrink as water moves from inside to outside the cells as a result of osmosis.

Osmosis refers to the movement of water from the region of high solvent or water concentration to the region of low solvent or water concentration.

In this condition, the concentration of water in a concentrated salt (hypertonic) solution would be less as compared to that of a red blood cell.

Thus, the water from inside the cell will move outside the cell. Consequently, the cell would shrink in size.

If we place human red blood cells in a concentrated salt solution, then they shrink as water moves from inside to outside the cells as a result of osmosis.

Further Explanation:

Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides.  

For a cell to survive, the ion concentrations outside and inside the cell should be the same. Also, the water concentration is limited because a higher concentration of water can burst and swell the cell. Osmosis is crucial in the biological systems as the membranes are semi-permeable. Also, focus on maintaining the equilibrium on both sides and prevent the bursting of the cell. If a blood cell is placed in a beaker that is filled with the concentrated salt solution then the solvent present in the cell moves outside to the cell to maintain the homeostasis of the cell this phenomenon is mainly known as exo-osmosis.
