Find the amount of work done in emptying a cylindrical tank completely filled with kerosene. Assume that the radius of the cylindrical tank is 3 m, height is 6 m, and the density of kerosene is 817.15 kg/m3

Answers

Answer 1

Answer: The formula for the work done in emptying a tank is this:
W = ωyV

where
ω is the specific weight
y is the center of gravity
V is the volume of the liquid

The specific weight can be calculated using the formula
ω = ρg
where
ρ is the density
g is the acceleration due to gravity

Solving for ω
ω = 817.15 kg/m3 (9.81 m/s2)
ω = 8016.24 N/m3

The center of gravity of a completely filled cylindrical tank is just 1/2 of the height. So,
y = 3 cm

The volume of the kerosene is just the volume of tank. Using the formula for the volume of a cylinder
V = πr²h
V = π (3²) (6)
V = 54π m³

Therefore, the word done is
W = 8016.24 (6) (54π)
W = 8159538.47 J or
W = 8.16 MJ

What are the three general types of questions that perception helps us answer regarding our environment?

Answers

Explanation:

Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.

An anthropologist finds a fossil that is 4 million years old. Its pelvis suggests it walked upright. Which species could the specimen belong to?Australopithecus africanus
Australopithecus afarensis
Homo habilis
Homo erectus

Answers

Australopithecus afarensis is hominin discovered in the Afar region in Ethiopia. He lived between 4 and 3 million years ago. The most famous fossil is named Lucy. Australopithecus africanus was dated as living between 3.3 and 2 million years ago. Homo habilis is much younger: 2.1 - 1.5 million years ago. Homo erectus is the youngest ( from 1.9 million - 70,000 years ago ). Answer: The specimen could belong to B ) Australopithecus afarensis.

Cell division is preceded by two growth phases. Besides growth, both G1 and G2a. contain checkpoints that determine if the cycle will continue.
b. help move chromosomes to the new daughter cells.
c. produce more chromosomes before the cell divides.
d. grow and produce enough cytoplasm to fill two cells.

Answers

The answer is a. contain checkpoints that determine if the cycle will continue. Cell cycle checkpoint are important mechanisms that control cell division. There are two checkpoints during the cell cycle: G1 and G2 checkpoint. The G1 checkpoint is right before the S phase. If something is wrong at the G1 checkpoint, the cell will not enter the S phase where DNA replication starts. The G2 checkpoint (DNA damage checkpoint) is right before the M phase. If DNA is damaged, the cell will not enter the M phase (mitosis).
