explain why a liquid rises in a capillary tube
1. explain why a liquid rises in a capillary tube
Jawaban:
A liquid rises in a capillary tube due to the phenomenon known as capillary action. Capillary action occurs when the cohesive forces between the liquid molecules are stronger than the adhesive forces between the liquid and the walls of the capillary tube.
When a liquid is placed in a capillary tube, the cohesive forces between the liquid molecules cause the liquid to be attracted to itself, while the adhesive forces between the liquid and the walls of the tube cause the liquid to be attracted to the walls. If the cohesive forces are stronger than the adhesive forces, the liquid will be pulled up the walls of the tube, resulting in the phenomenon known as capillary action.
Capillary action is commonly observed in small tubes or pores, such as those found in plants. In plants, capillary action is responsible for the movement of water and nutrients from the roots to the rest of the plant. It is also used in a variety of scientific and technological applications, such as in the design of inkjet printers and in the measurement of small amounts of liquid.

5. How to count surface tension?
Jawaban:
Maaf jika kurang jelas
Penjelasan:
Ketegangan permukaan diberikan oleh persamaan S = (phga / 2) di mana S adalah tegangan permukaan, p(atau rho) adalah keladatan cairan yang anda ukur, h adalah ketinggian cairan yang naik dalam tabung, g adalah akselerasi karena gravitasi yang berkerja pada cairan (9,8 m/ s2) dan a adalah jari-jari tabung kapiler.

10. susunlah kalimat berikut !! 1. has - an alcohol thermometer - a glass tube - with a bulb in the bottom 2. alcohol that expands - when the temperature rises - inside the tube - and contracts when the temperature falls - is colored 3. with mercury - some thermometers - are made
1. a glass tube with a bulb in the bottom has an alcohol termometer
2. when the temperature rises alcohol that expands inside the tube is colored and contracts when the temperature falls
3. some thermometers are made with mercury
maaf yaa kalo salah hehe=> Answer :
1.) An alcohol thermometer has a glass tube with a bulb in the bottom.
2.) When the temperature rises alcohol that expands inside the tube is colored and contracts when the temperature falls.
3.) Some thermometers are made with mercury.
Maaf jika salah. Semoga membantu ^_^

12. A uniform capillary tube, closed at one end, contained air trapped by a thread of mercury 85mm long. When the tube was held horizontally, the length of the air column was 50mm. When it was held vertically with the closed end downwards, the length was 45mm. Find the atmospheric pressure in Pascals (Take g = 10m/s squared, density of mercury = 14000 kg/metre cubed)

13. A cube with a volume of 27 cm³. Calculate the total surface area of the cube, in cm².
Jawaban:
54cm²
___________________________
To find the surface area of a cube, first find the side lengths
formula :
V = s³
or
[tex] \tt s = \sqrt[3]{V} [/tex]
[tex] \tt s = \sqrt[3]{27} [/tex]
[tex] \tt s = \sqrt[ \cancel3]{ {3}^{ \cancel3} } [/tex]
[tex] \tt s = 3cm[/tex]
___________________________
Surface area :
[tex] \tt S = 6 \times {s}^{2} [/tex]
[tex] \tt S = 6 \times {3}^{2} [/tex]
[tex] \tt S = 6 \times 9[/tex]
[tex] \boxed{\tt \red{S =54 {cm}^{2}} }[/tex]

16. In a scientific experiment, theone variable that changesduring the experiment is calledthe .... variable.
Jawaban:
The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.

18. An elevator with a mass of 2000 kg rises with an acceleration of 1.0 m/s/s. What is the tension in the supporting cable?
Jawaban:
T - W = ma
W = mg
T = m(g + a)
Asumsikan g = 10 m/s^2
T = 2000(10 + 1)
T = 22000N
Penjelasan:
maaf kalo salah
Jawaban:
22000 newton
Penjelasan:
m = 2000kg
a = 1 m/s²
g = 10 m/s²
berat elevator terhadap bumi = m x g = 20000 Newton
tegangan yang ditimbulkan harus melebihi berat elevator terhadap bumi
dengan kata lain percepatan yang dihasilkan harus lebih besar dari percepatan gravitasi
sehingga percepatan sebenarnya tanpa pengaruh gravitasi = g + a = 10 + 1 = 11 m/s²
Tegangan yang dihasilkan = m x 11 = 2000 x 11 = 22000 newton
19. Q.A cylinder has a diameter of 20 cm and a height of 16 cm. Calculate areathe tube surface!
Jawab:
Penjelasan dengan langkah-langkah:
An area the tube surface = 2πr (r + h)
diameter = 20
r = 20/2 = 10
h = 16
An area the tube surface = 2 (3,14) (10) (10 + 16)
An area the tube surface = 62,8 (26)
An area the tube surface = 1.632,8 cm²
Penjelasan dengan langkah-langkah:
Area Of The Tube surface = 2nr(r + h)Diametre = 20 cmr = D/2 = 20/2 = 10 cmheight = 16 cmMaka,
= 2nr(r + h)
= 2(3,14)(10)(10 + 16)
= 6,28(10)(10 + 16)
= 62,8(26)
= 1.632,8cm^2
