What is the potential energy of a 10-kg book that is placed on a shelf that is 2.5 meters high?
The potential energy of the book is 245 J.
SOLUTION:We are given the following:
mass m = 10 kgheight above a reference point h = 2.5 mUse the formula for potential energy. ( g = 9.8 m/s² )
[tex] \qquad {\boxed{\sf P.E._{grav} = m \times g \times h}} [/tex]
[tex] \sf P.E._{grav} = (10\:kg) \times (9.8\: \frac{m}{s^2}) \times (2.5\:m) [/tex][tex] \sf P.E._{grav} = (10\:kg) \times (24.5\: \frac{m^2}{s^2}) [/tex][tex] \sf P.E._{grav} = {\boxed{\sf {245\:J}}} [/tex]Therefore, the potential energy of the book is 245 J.
HOPE IT HELPS!1. How does Air move in Earth's Atmosphere?
Answer:
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... When the air cools, it drops back to the ground, flows back towards the Equator, and warm again. The, now, warmed air rises again, and the pattern repeats. This pattern, known as convection, happens on a global scale.
describe how the plasma membrane helps maintain homeostasis
Answer:
The plasma membrane, also called the cell membrane or phospholipid bilayer, is the sack that surrounds cells. ...

Name the 2 different types of endoplasmic reticulum and explain the function of each type endoplasmic reticulum to the cell . (ie - what does each one 'produce', or make for the cell)
Answer:
The surface of the rough endoplasmic reticulum (ER) is covered in ribosomes, while the smooth endoplasmic reticulum is not covered in ribosomes.
Explanation:
Hence their terms, rough and smooth endoplasmic reticulum, the smooth is like a fine tube whereas the rough consists of ribosomes on its surface. Both the smooth and rough endoplasmic reticulum work together, delegate tasks and are the site for production and storage of proteins.
Smooth ER is responsible for storage and lipids production, while the rough ER is responsible for production of proteins and some hormones.

what hormone directly opposes the actions of natriuretic hormones?
The hormone that directly opposes the actions of natriuretic hormones is aldosterone.
Aldosterone is a hormone produced by the adrenal glands, specifically the adrenal cortex. It acts on the kidneys to promote the reabsorption of sodium ions and the excretion of potassium ions.
Natriuretic hormones, on the other hand, promote the excretion of sodium ions and the reabsorption of potassium ions in the kidneys, leading to increased urine production and decreased blood volume.
Therefore, aldosterone counteracts the effects of natriuretic hormones by increasing sodium reabsorption and reducing potassium excretion, which helps to retain water and maintain blood pressure.
In summary, while natriuretic hormones promote sodium excretion and water loss, aldosterone works in the opposite direction by promoting sodium reabsorption and water retention.

lon khoáng nào đóng vai trò đặc biệt quan trọng trong quá trình đông máu?
Answer:
1. Xét nghiệm yếu tố đông máu để làm gì?
Để đánh giá khả năng đông máu như thế nào và quá trình đông máu kéo dài trong thời gian bao lâu, các bác sĩ sẽ tiến hành xét nghiệm các yếu tố đông máu.
Quá trình đông máu sẽ bảo vệ cơ thể bạn khi bị chảy máu. Tuy nhiên, nếu một cục máu đông hình thành trong tĩnh mạch bình thường thì đây là điều hết sức nguy hiểm vì có thể khiến cho dòng máu bị chặn đến tim, não, phổi.
Khi thực hiện xét nghiệm các yếu tố đông máu, sẽ biết được nguy cơ bạn bị chảy máu quá nhiều khi bị thương hay không hoặc có nguy cơ bị đột quỵ không.

2. Các yếu tố đông máu gồm những gì?
Fibrinogen
Fibrinogen là yếu tố ảnh hưởng lớn đến quá trình đông máu
Sau đây là các yếu tố ảnh hưởng đến quá trình đông máu:
I - Fibrinogen: Fibrinogen là huyết tương có trọng lượng phân tử là 340.000, hòa tan được. Yếu tố này có mặt trong huyết tương với nồng độ là từ 100-700mg/ 100mL. Đa số Fibrinogen được tạo ra ở gan, vì thế đối với những bệnh nhân bị bệnh gan thì lượng Fibrinogen giảm trong máu tuần hoàn, sự đông máu bị ngăn cản.
II- Prothrombin: Prothrombin là protein huyết tương có trọng lượng phân tử là 68.700, có mặt trong huyết tương với nồng độ là 15mg/100mL. Gan sản xuất Prothrombin liên tục, chính vì vậy nếu gan bị suy yếu, lượng prothrombin sẽ giảm, gây ức chế sự đông máu.
III- Thromboplastin mô: Yếu tố này tham gia vào cơ chế đông máu ngoại sinh, thay thế phospholipid tiểu cầu và các yếu tố huyết tương. Bên cạnh đó, thromboplastin còn có tác dụng chống nhiễm khuẩn.
IV- Ca++: Quá trình đông máu không thể không có mặt của loại ion này.
V- Proaccelerin: Khi có nhiều ion Ca++ thì yếu tố này mất hoạt tính. Khi không có proaccelerin, người ta điều chế huyết tương bằng cách để lâu huyết tương lấy từ máu chống đông với oxalat.
VII- Proconvertin: Trọng lượng phân tử của yếu tố này là 60.000. Hoạt tính của yếu tố này trong huyết tương sẽ bị giữ lại trên màng lọc amiang;
VIII- Antihemophilic A: Để tổng hợp yếu tố này, phụ thuộc vào rất nhiều gen trong các nhiễm sắc thể khác nhau. Thường thì antihemophilic được tổng hợp chủ yếu từ gan, lá lách và hệ thống võng nội mô. Khi thiếu ion Ca++ thì yếu tố này mất hoạt tính. Đây là yếu tố chống huyết hữu B;
IX- Antihemophilic B: Chống huyết hữu A.
X- Stuart: Stuart có trong huyết tương, ở dưới dạng không hoạt động. Trong quá trình đông máu nội sinh có sự tham gia của yếu tố này. Khi cho thromboplastin mô vào quá trình đông máu ngoại sinh, sẽ không còn yếu tố stuart.
XI- Plasma Thromboplastin Antecedent (PTA): Quá trình khởi phát đông máu nội sinh không thể thiếu yếu tố PTA.
XII- Hageman: Động lực để tạo thành một loạt phản ứng dẫn đến đông máu là sự tiếp xúc giữa yếu tố XII với mặt trong mạch máu tổn thương cùng sự có mặt của phospholipid tiểu cầu. Bên cạnh chức năng hoạt hóa hệ đông máu, Hageman còn hoạt hóa hệ đông máu, hệ bổ thể và hệ chống đông.
XIII - Fibrin Stabilizing Factor ( FSF): yếu tố này có hoạt tính bền vững trong huyết tương, ổn định fibrin.
