Le manque de sommeil peut réduire la production d'insuline par le pancréas. L'insuline est responsable de métaboliser le sucre dans le sang. De quel ordre peut être la réduction d'insuline?Lecteur immersif
Answer:
Very big.
Explanation:
Very big reduction occurs in insulin production when a person did not sleep in 24 hours. Due to lack of sleep, reduction occurs in the production of insulin by the pancreas. Insulin is a hormone that is responsible for metabolizing sugar in the blood and if insulin is not secreted by the pancreas in normal concentration so the person get diabetes disease due to increasing amount of glucose in the blood.

A car slows down from -27.7m/s to -10.9m/s while undergoing a displacment of -105m. What was its acceleration?
Given :
A car slows down from -27.7 m/s to -10.9 m/s while undergoing a displacement of -105 m.
To Find :
The acceleration of the car.
Solution :
We know, by equation of motion :
[tex]2as = v^2 -u^2\\\\a = \dfrac{v^2 -u^2 }{2s}\\\\a = \dfrac{(-10.9)^2 - ( -27.7)^2}{2\times ( -105 )}\\\\a = 3.088\ m/s^2[/tex]
Therefore, acceleration of the car is 3.088 m/s².
PLZ HELP IM REALLY CONFUSED a boy is playing catch with his friend. He throws the ball straight up. When it leaves his hand, the ball (2kg) is traveling 10m/s. Whats the ball's kinetic energy just as it leaves the boy's hand? What is the potential energy of the ball when it reaches the highest point
Answer:
K.E = 100 J
Final P.E = 100 J
Explanation:
The kinetic energy of any object can be given by the following formula:
[tex]K.E = (\frac{1}{2})mv^{2}[/tex]
where,
K.E = Kinetic Energy
m = mass of ball = 2 kg
v = speed of ball
Initially, v = 10 m/s. Therefore, the initial K.E is given as:
[tex]K.E = (\frac{1}{2})(2\ kg)(10\ m/s)^{2}[/tex]
K.E = 100 J
Now, at the highest point the K.E of the ball becomes zero. because the ball stops for a moment at the highest point and its velocity becomes zero. So, from Law of Conservation of energy:
Initial K.E + Initial P.E = Final K.E + Final P.E
Initial P.E is also zero due to zero height initially.
K.E + 0 = 0 + Final P.E
Final P.E = 100 J

See how a block and tackle system can increase your mechanical advantage. You will need two broomsticks, a rope, and two helpers.
A. Give each helper a broom stick and have them stand facing each other holding the broomstick firmly in both hands in a horizontal position. The broomsticks should be at the same level, about two feet apart.
B. Tie one end of the rope to one of the broomsticks. (You may need to have one of your helpers hold the knot firmly in one hand as he or she holds the broomstick to help anchor it.)
C. Wrap the rope around the other broomstick, as in a simple pulley system, and pull on the free end of the rope. Your helpers should resist your pulling. What happens? Can you pull the broomsticks together?
D. Now weave the rope back over the first broomstick, so you have a double pulley. Pull on the free end. What happens now? Can you pull the broomsticks together? What is your mechanical advantage?
E. Try weaving the rope over the broomsticks one or two more times. Describe what happens, and state the mechanical advantage of each situation.
F. Write a summary of what happened and an explanation using the terms:
force
distance
work
mechanical advantage
-) In what ways can you change an object's kinetic energy?
Answer:
If we want to change the kinetic energy of a massive object, we must do work on it. For example, in order to lift a heavy object, we must do work to overcome the force due to gravity and move the object upward. If the object is twice as heavy, it takes twice as much work to lift it the same distance.
Explanation:

A 43 kg box is being pushed and pulled by
three forces. The first force is 155 N to the
right. The second force is 227 N to the left.
The third force is 113 N to the right. What is
the acceleration of the box?
Answer:
a = - 0.209 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
We will take the positive forces to the right and the negative forces to the left.
[tex]155-277+113=43*a\\-9=43*a\\a = - 0.209[m/s^{2} ][/tex]
The negative sign means that the box accelerates in a negative direction to the left.
The ball as launched horizontally off a 200m cliff. The initial velocity is 40m/s.
Find the time it takes to hit the ground.
Find the RANGE, distance traveled horizontally.
Find the final vertical velocity.
Answer:
a. 6.39 s b. 255.6 m c. 62.6 m/s
Explanation:
a. Find the time it takes to hit the ground.
Using y = ut + 1/2gt² where y = height of cliff = 200 m, u = initial vertical velocity of ball = 0 m/s, g = acceleration due to gravity = 9.8 m/s² and t = time taken for ball to hit the ground.
So, substituting the values of the variables into the equation, we have
200 m = 0 m/s × t + 1/2 × 9.8 m/s² × t²
200 m = 0 + (4.9 m/s²)t²
200 m = (4.9 m/s²)t²
dividing both sides by 4.9 m/s², we have
t² = 200 m ÷ 4.9 m/s²
t² = 40.82 s²
taking square root of both sides, we have
t = √(40.82 s²)
t = 6.39 s
b. Find the RANGE, distance traveled horizontally.
The range is the horizontal distance traveled by the ball, R = vt where v = horizontal velocity of ball = 40 m/s and t = time taken for ball to hit the ground = 6.39 s
So, R = vt
= 40 m/s × 6.39 s
= 255.6 m
c. Find the final vertical velocity.
Using v = u - gt where u = initial vertical velocity of ball = 0 m/s, v = final velocity of ball, g = g = acceleration due to gravity = 9.8 m/s² and t = time taken for ball to hit the ground = 6.39 s.
So, substituting the values into the equation, we have
v = 0 m/s - 9.8 m/s² × 6.39 s
v = -62.62 m/s
v ≅ -62.6 m/s
answers to anatomy and physiology coloring workbook chapter 7 the nervous system page 142-144
Answer:the nervous system
Explanation:
Anatomy vs Physiology as the Anatomy is the study of the structure of living organisms, while Physiology is the study of the function of living organisms.
What is the nervous system?
Nervous System the nervous system integrates and controls the body's functions through electrical and chemical signaling. Anatomy focuses on the physical makeup of living organisms and their components, such as organs, tissues, and cells.
This includes the external and internal structures of the body, as well as the relationships between these structures. On the other hand, Physiology examines how living organisms perform the functions necessary for life, such as respiration, digestion, circulation, and movement.
Physiology explores the processes and mechanisms behind these functions, including biochemical reactions, electrical and mechanical events, and hormonal regulation.
The nervous system consists of the brain, spinal cord, and a network of nerves that extend throughout the body. It is responsible for collecting, processing, and transmitting information about the internal and external environment to the rest of the body.
The nervous system also regulates the activity of other systems in the body, such as the endocrine, cardiovascular, and respiratory systems.

A 150-turn coil of wire moves perpendicularly through a uniform magnetic field in 1.1 s. If the field increases uniformly from 0.00 T to 0.95 T and each coil of wire has an area of 1.4 m2, use Faraday’s law of magnetic induction to find the magnitude of the induced emf in the coil:
a. 180 V
b. 1800 V
c. -180 V
d. -18 V
Answer:
-180 V
Explanation:
Given that,
No. of turns, N = 150
If the field increases uniformly from 0.00 T to 0.95 T and each coil of wire has an area of 1.4 m²
The coil will move perpendicular through a uniform magnetic field in 1.1 s.
We need to find the magnitude of the induced emf in the coil. The formula for the induced emf is given by :
[tex]\epsilon=\dfrac{-d\phi}{dt}\\\\=\dfrac{-d(BA)}{dt}\\\\=-A\dfrac{dB}{dt}[/tex]
Put all the values,
[tex]\epsilon=-NA\dfrac{dB}{dt}\\\\=-150\times 1.4\times \dfrac{0.95-0}{1.1}\\\\=-181.36\ V[/tex]
Out of four options, induced emf is (-180 V)
So, induced emf in the coil is (-180 V). Hence, the correct option is (c).

Robin throws a penny up in the air. If the penny's initial velocity is 1.0m/s[up] and it is launched from a height of 1.5 m, what is the maximum height of the penny above the ground?
Answer:
1.55m
Explanation:
The formula for calculating the maximum height is expressed as;
H = u²/2g
u is the initial velocity
g is the acceleration due to gravity
Substitute
H = 1²/2(9.8)
H = 1/19.6
H = 0.051m
Since it is launched form a height of 1.5m, the height above the ground will be 1.5+0.051 = 1.55m

A sled accelerates to the right with a value of 10 m/s^2. There is a force acting to the left the is 80 N. If the mass of the sled is 40 kg, what must be the force acting to the right?
Answer:
m/s^-30
Explanation:
what is the correct answer?
Answer:
Option (4)
Explanation:
Given polynomial is,
P(x) = 1x³ - 7x² + 2x + 40
If (x - 5) is a factor of the given polynomial,
Synthetic division by x = 5,
5 | 1 -7 2 40
↓ 5 -10 -40
1 -2 -8 0
Therefore, factored form of the polynomial will be,
P(x) = (x - 5)(x²- 2x - 8)
Now we further factorize the expression (x² - 2x - 8),
(x² - 2x - 8) = x²- 4x + 2x - 8
= x(x - 4) + 2(x - 4)
= (x + 2)(x - 4)
Now fully factored form of the polynomial will be,
P(x) = (x - 5)(x + 2)(x - 4)
Therefore, remaining factors of the polynomial other than (x - 5) are (x - 4)(x + 2)
Option (4) will be the correct option.

A student pulls a 50-newton sled with a force having a magnitude of 15 newtons. What is the magnitude of the force that the sled exerts on the student?
Answer:
Force = 35 N
Explanation:
From Newton's third law of motion, the boy must apply a force greater than the weight of the sled to lift it.
weight of sled = mg
where m is its mass and g the force of gravity on it.
weight of sled = 50 N
Force applied by the boy on the sled = 15 N
Since the force applied on the sled by the boy is lesser than the weight of the sled, then;
Force that the sled exerts on the student = 50 - 15
= 35 N
The force exerted by the sled on the student is 35 N.
