The mercury manometer of fig. P2.57 indicates a differential reading of 0.30 m when the pressure in pipe a is 30-mm hg vacuum. Determine the pressure in pipe
b.
Answer:
The pressure in pipe b is 33.4 kpa.
Explanation:
Given that,
Pressure in pipe a = 30 mm hg vacuum
Differential reading = 0.30 m
We need to calculate the pressure in pipe b
Using diagram
[tex]P_{B}+W_{oil}(h_{1}+h_{2})-W_{Hg}(h_{2})-W_{H_{O}}(h_{1})=P_{A}[/tex]
Where, P = pressure
W= specific weight
Put the value into the formula
[tex]P_{B}+W_{oil}(0.15+0.30)-W_{Hg}(0.3)-W_{H_{2}O}(0.15)=-W_{Hg}(0.030)[/tex]
Put the value of specific weight
[tex]P_{B}=-(133)\times(0.030)-(8.95)\times(0.45)+133\times(0.3)+9.80\times0.15[/tex]
[tex]P_{B}=33.4\ kPa[/tex]
Hence, The pressure in pipe b is 33.4 kpa.

Which organelle packages materials and distributes them throughout the cell?
O lysosome
O chloroplast
O Golgi body
O cell membrane
Answer:
golgi body
Explanation:
i took the test
Organelle packages materials and distributes them throughout the cell through the Golgi body (also known as the Golgi apparatus or Golgi complex). The correct option is C.
The Golgi body plays a crucial role in the packaging, modifying, and sorting of proteins and lipids synthesized in the endoplasmic reticulum (ER). It receives these molecules from the ER and then modifies them, such as by adding sugars or lipids. The Golgi apparatus then packages these molecules into vesicles and distributes them to their appropriate destinations within the cell, such as other organelles or the cell membrane.
A. Lysosome: Lysosomes are organelles responsible for the digestion of waste materials, cellular debris, and foreign substances. They contain enzymes that break down various molecules. Lysosomes are not involved in packaging and distributing materials throughout the cell.
B. Chloroplast: Chloroplasts are organelles found in plant cells responsible for photosynthesis, the process by which sunlight is converted into chemical energy. Chloroplasts are involved in producing energy-rich molecules (such as glucose) rather than packaging and distributing materials within the cell.
D. Cell membrane: The cell membrane (also known as the plasma membrane) is a semipermeable barrier that surrounds the cell, separating its internal environment from the external environment. While the cell membrane controls the entry and exit of substances into and out of the cell, it is not directly involved in packaging and distributing materials within the cell.
Therefore, the Golgi body is the correct answer as it specifically carries out the task of packaging and distributing materials throughout the cell.

Answer:
c gasses
Explanation:
Liquid and gases state(s) of matter have no definite shape or volume
What is the matter?Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
The solid has a definite shape and definite volume because the atoms and molecules of the solid are very close to each other forming a great bond structure.
The liquid and gaseous state have their atoms and molecules apart from each other forming a loose bonding structure because this liquid does not have a fixed shape it takes the shape of the container, similarly, gases, their atoms are far apart from each other that's why they don't have fixed shape or the fixed volume.
States of matter those have no definite shape or volume are liquids and gases.

a marble is shot horizontally from a table .8 m High, and it lands, 1.2 meters away horizontally. what was the initial velocity of the marble as it left the table
Answer:
3 m/s
Explanation:
First, find the time it takes to land.
Given in the y direction:
Δy = 0.8 m
v₀ = 0 m/s
a = 10 m/s²
Find: t
Δy = v₀ t + ½ at²
0.8 m = (0 m/s) t + ½ (10 m/s²) t²
t = 0.4 s
Next, find the velocity needed to travel 1.2 m in that time.
Given in the x direction:
Δx = 1.2 m
a = 0 m/s²
t = 0.4 s
Find: v₀
Δx = v₀ t + ½ at²
1.2 m = v₀ (0.4 s) + ½ (0 m/s²) (0.4 s)²
v₀ = 3 m/s

If you walk 30 meters forwards, and then turn around and walk 25 meters backwards, what is the distance that you walked? What displacement do you have after this walk?
Given :
Walk in forward direction is 30 m .
Walk in backward direction is 25 m .
To Find :
The distance and displacement .
Solution :
We know , distance is total distance covered and displacement is distance between final and initial position .
So , distance travelled is :
D = 30 + 25 m = 55 m .
Now , we first move 30 m in forward direction and then 25 m in backward direction .
So , displacement is :
D = 30 - 25 m = 5 m .
Therefore , distance and displacement covered is 55 m and 5 m respectively .
Hence , this is the required solution .

A biker goes out for a ride and begins riding North at 18 km/h for 200 minutes, then the driver turns around and rides at 12 km/h South for another 50 minutes.
Answer:
Explanation:
18 km / h
= 300 m / min
12 km / h = 200 m / min
distance travelled in 200 minutes = 300 x 200 = 60000 m
distance travelled in 50 minute in return journey = 200 x 50 = 10000 m
total distance travelled = 70000 m
total time = 250 minute
speed = 70000 / 250
= 280 m / min
= 16.8 km / h
Total displacement = 60000 - 10000 = 50000 m
total time = 250 min
velocity = 50000 / 250
= 200 m / min
= 12 km / h

Answer:
A.) 42.7 m/s
B.) 0.33 m/s^2
C.) 90 kg
Explanation:
A.) If Justin races his Chevy S-10 down highway 37 north for 2,560 meters in 60 seconds, what is his velocity?
Velocity = displacement/time
Velocity = 2560/60
Velocity = 42.67 m/s
B.) The Chevy S-10 started rounding at 10 meters per hour. What is the acceleration at 30 seconds on the highway?
Acceleration = velocity/time
Acceleration = 10/30
Acceleration = 0.33 m/s^2
C.) The S-10 has a force of 30 N. What is the mass of the car?
Force = mass × acceleration
30 = mass × 0.33
Mass = 30/ 0.33
Mass = 90 kg
The speed needed to escape the pull of Earth's gravity is 11.3 km/s. What is this speed in mi/h? (1 mile = 1609 m)
Answer:
11.3 km/sec * 1000 m/km / 1609 m/mi = 7.02 mi / sec
7.02 mi/sec * 3600 sec / hr = 25,300 mph
The value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.
Given the following data;
Speed = 11.3 km/s1 mile = 1609 mIn this exercise, you're required to convert the value of the speed needed to escape the pull of Earth's gravity in kilometer per seconds (km/s) to miles per hour (mi/h).
Conversion:
1 mile = 1.609 kilometer
X mile = 11.3 kilometer
Cross-multiplying, we have;
[tex]1.609[/tex] × X = [tex]11.3[/tex]
[tex]X = \frac{11.3}{1.609}[/tex]
X = 7.0230 miles
Since we know that one (1) hour is equal to 3600 seconds, we would multiply the value of X by 3600 in order to convert it to miles per hour (mi/h).
X = 7.0230 × 3600
X = 25282.8 mi/h
Therefore, the value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.
