Explanation:
THIS is because Anatomy the branch of life studyconcerned with the study of the structure of organisms and their parts
Whilw physiology studies the functioning of these parts
The branch of medical science that considers the functions of anatomical parts is called physiology, whereas anatomy describes the form and organization of body parts.
Physiology is the study of how body parts function and work together to maintain life processes and perform specific tasks. It focuses on the mechanisms and processes that underlie bodily functions, such as digestion, circulation, and muscle contraction.
On the other hand, anatomy is concerned with the structure, shape, and organization of body parts, including organs, tissues, and cells.
Together, anatomy and physiology provide a comprehensive understanding of the human body and its intricate workings, helping medical professionals diagnose and treat illnesses and maintain overall health.
Therefore, The branch of medical science that considers the functions of anatomical parts is called physiology.

An apple is falling from a tree. Disregarding air resistance, which diagram shows the free-body diagram of the force
or forces acting on the apple?
Answer: Second choice (straight down arrow)
Explanation:
I just did it.
Disregarding air resistance, the diagram showing the free-body diagram of the force or forces acting on the apple is second one.
What is free falling?When an object is released from rest in free air considering no friction, the motion is depend only on the acceleration due to gravity, g.
Given is an apple is falling from a tree.
When apple is falling down, the gravity will attract the apple towards the center of the Earth. Air resistance is not considered, otherwise it would be acting upwards.
Normal force will not act as apple in not placed on any kind of surface.
So, the only force acting is force of gravity also called as weight of apple.
Thus, the free-body diagram of the force or forces acting on the apple is second one.

Calculate the time taken by the sphere to
hit the surface of the Moon.
A 1.8 S
C 3.3 s
B 2.6 s
D 4.2 s
Answer:
C 3.3 s
Explanation:
Given:
Δy = 9 m
v₀ = 0 m/s
a = ⅙ (9.8 m/s²) = 1.63 m/s²
Find: t
Δy = v₀ t + ½ at²
9 m = (0 m/s) t + ½ (1.63 m/s²) t²
t = 3.3 s
A man is lifting a piano that weighs 800 N through a distance of 10 meters using a pulley system. The man pulls the rope a total distance of 100m. What force does the man need to apply to the rope?
Answer:
The force the man applied is 80 N
Explanation:
weight of the load, L = 800 N
distance traveled by the load, a = 10 m
distance traveled by the effort, b = 100 m
Output work = load x distance moved by the load
Output work = 800 x 10 = 8000 J
Input work = Effort x distance moved by effort
Input work = Effort x 100 m
Assuming an ideal machine; no friction effect, the input work will be equal to output work.
Effort x 100 m = 8000 J
Effort = 8000 / 100
Effort = 80 N
Therefore, the force the man applied is 80 N
A ball is held at rest and then dropped. The final velocity of the ball was 45 m/s just before it hit the ground. How high was the ball when it was dropped?How much time past before the ball hit the ground?
Answer:
a) y = 103.21 m
b) t = 4.6 s
Explanation:
a) The height at which the balls was is given by:
[tex] V_{f}^{2} = V_{0}^{2} - 2g(y_{f} - y_{0}) [/tex]
Where:
[tex]y_{f}[/tex]: is the final height = 0
[tex]y_{0}[/tex]: is the initial height =?
[tex]V_{f}[/tex]: is the final velocity = 45 m/s
[tex]V_{0}[/tex]: is the initial velocity = 0 (is held at rest
g: is the gravity = 9.81 m/s²
Hence, the height is:
[tex] y_{0} = \frac{V_{f}^{2}}{2g} = \frac{(45 m/s)^{2}}{2*9.81 m/s^{2}} = 103.21 m [/tex]
b) The time before the ball hit the ground is:
[tex] V_{f} = V_{0} - g*t [/tex]
[tex] t = -\frac{V_{f}}{g} = -\frac{- 45 m/s}{9.81 m/s^{2}} = 4.6 s [/tex]
Therefore, 4.6 seconds passed before the ball hit the ground.

12. The windings of a particular type of DC motor are in its rotor. The magnetic field is reversed during the rotation of the rotor by means of the
A. field magnets.
B. commutator.
C. applied power source reversal.
D. armature coil split windings.
Answer:
B. commutator
Explanation:
The DC motor has a commutator, to keep the rotor rotating. The rotor of the DC motor usually stop spinning once it aligns with the magnetic field. However, the commutator would reverse the current through the stator and in this process reverse the magnetic field. This ensures continuous spinning of the rotor.
Therefore, the correct option is "B. commutator."

How can Newton’s laws explain why the brain is in danger of injury when there is impact to the head?
Answer:
The brain moves inside the skull with a force equal and opposite to that of the impact.
Explanation:
the liquid pressure varies with depth why
Explanation:
Hey, there!
The liquid pressure varies with depth because liquid pressure is directly proportional to the depth of liquid from the free surface of the liquid. so, more the depth more the pressure and less the depth less the pressure.

The atmospheric pressure on a mountain is 550 mmHg and 1 atm is equal to 760 mmHg. What is the pressure in atm? Give your answer to 2 significant figures760 mmHg what is the pressure in atm?
Answer:
0.72 atm
Explanation:
Given that the atmospheric pressure on a mountain is 550 mmHg.
Where 1 atm is equal to 760 mmHg.
To Convert millimetre mercury (mmHg) into atmospheric pressure units (atm) , divide the magnitude of pressure by 760. That is,
Pressure = 550/760
Pressure = 0.724 atm
Therefore, pressure in atm is 0.72 atm in two significant figures

Answer:
d_total = 12 m
Explanation:
This is a kinematics problem, in the attachment we can see the problem graph, they ask us how much the distance is worth for all the time of 24 s.
The total distance is
d_total = d₁ + d₂ + d₃
as in the graph the part of d₂ is horizontal (v=0) the distance is zero d₂ = 0
the distance d₁ is
d₁ = 12 -6 = 6 m
the distance d₃
d₃ = 6 -0 = 6 m
therefore the total distance traveled is
d_total = 6 + 0 + 6
d_total = 12 m

Answer:
An ammeter should be connected in the series while the voltmeter in parallel.
Explanation:
Ammeter is the device used to measure the electric current. So , the total current flowing through the circuit must pass through the ammeter. Thus , it should be connected in series. While voltmeter is a device used to measure the potential difference between two ends. Therefore, voltmeter should be connected in parallel to measure the potential difference across two ends.

How would you express B⃗ using unit vectors? Express your answers in terms of the unit vectors x^ and y^. Use the unit vector button under the templates menu in the answer box to create unit vectors.
Answer:
B = B (cos θ x ^ + sin θ y ^)
Explanation:
To represent the magnetic field B using unit vectors, the magnitude of the field and the angle with respect to some coordinate axis must be known. Having this information, trigonometry can be used.
Suppose that the angle we have is with respect to the positive side of the x-axis, let's use trigonometry
cos θ = Bₓ / B
sin θ = [tex]B_{y}[/tex] / B
Bx = B cos θ
B_{y} = B sin θ
so the resulting vector is
B = Bₓ i ^ + B_{y} j ^
unit vectors
x ^ = i ^
y ^ = j ^

B = B (cos θ x ^ + sin θ y ^)

Help ????????????????
Answer:
Inertia.
Explanation:
You are moving with a speed of 1 m/s. You are carrying a tray and the ball is at rest in the tray. You stops and the ball rolls off the tray. Whenever you starts moving with a speed of 1 m/s and when ball is at rest, due to inertia of motion the ball comes in motion. But when you stops, the ball is still in motion due to its inertia.
Hence, due to inertia the ball roll off the tray.
