B.
The spine in the only part of the body that is directly connected to the brain.
C.
The spine houses much of the central nervous system, which controls movement.
D.

Due to paralysis, the result is severe spinal injuries. This is often the case because the spine houses much of the central nervous system, which controls movement. Hence, option C is correct.
What is Paralysis?You might become paralyzed, and unable to move on your own when something interferes with the nerve impulses that muscles receive from the brain. Strokes, spinal cord injuries, and neurological diseases like multiple sclerosis are among the common causes of paralysis.
When you are unable to move your muscles voluntarily, you are said to be paralyzed. Paralysis results from nerve system issues.
Muscles receive messages from healthy nerves. This causes the muscles to contract. When you’re paralyzed, or have paralysis, you can’t move certain parts of your body.
Hence, it concludes that option C is correct.

what is the weight of a 1.8 kg computer
Answer:
17.64 Newtons
Explanation:
In order to find the weight of an object we take the mass in kilograms and multiply it by the gravitational constant (9.8), which is 1.8 * 9.8 = 17.74 Newtons.
Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Weight of body is force due to gravity,
F = mg
F = 1.8*9.8
F = 17.64 N
Weight of the body is given as 17.64 N.
Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

An object is moving initially with a velocity of 5.6 m/s. After 3.1 s the object's velocity is -2.7 m/s. What is the object's average acceleration during this time
Answer:
-2.68m/s²
Explanation:
To find acceleration use the formula:
acceleration = change in velocity ÷ time
change in velocity = -2.7 - 5.6 = -8.3m/s (final velocity - initial velocity)time = 3.1sSubstitute in the values:
acceleration = -8.3 ÷ 3.1
acceleration = -2.67741.. ≈ -2.68m/s²

which of the following is an example of the law of multiple proportions?
The answer option which is an example of the law of multiple proportions is: B) Two different compounds formed from carbon and oxygen have the following mass ratios: 1.33 g O: 1 g C and 2.66 g O: 1 g C.
The Law of Multiple Proportions is also referred to as Dalton's Law and it states that when two chemical elements combine to form more than one chemical compound, the masses (weights) of one chemical element that combine with a fixed mass (weight) of the other chemical element will always be in a ratio of small whole numbers.
According to the Law of Multiple Proportions, when two chemical elements combine to form two different chemical compound, the masses (weights) of one chemical element that combine with 1 gram of the other chemical element can be expressed as a ratio of small whole numbers.
For example, carbon and oxygen react to form either carbon monoxide and carbon dioxide.
Carbon monoxide (CO):
12 grams of C = 16 grams of O.
1 gram of C = 1.33 gram of O.
Carbon dioxide ([tex]CO_2[/tex]):
12 gram of C = 32 grams of O.
1 gram of C = 2.66 gram of O.
Ratio of oxygen (O) = 16:32 = 1:2 (Law of Multiple Proportions).

Help if you understood pleas and rhanks
Answer:
the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s
Explanation:
The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.
To calculate the acceleration of the object at 8 seconds, we need to look at the change in velocity over time (acceleration is the rate of change of velocity).
Given the graph, we can see that at 8 seconds, the velocity of the object is 6 m/s.
Now, let's find the change in velocity between 8 seconds and 10 seconds:
Change in velocity = Final velocity - Initial velocity
Change in velocity = 2 m/s - 6 m/s
Change in velocity = -4 m/s
Next, find the time interval between 8 seconds and 10 seconds:
Time interval = Final time - Initial time
Time interval = 10 s - 8 s
Time interval = 2 seconds
Now, calculate the acceleration:
Acceleration = Change in velocity / Time interval
Acceleration = (-4 m/s) / (2 s)
Acceleration = -2 m/s²
The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

Which force is making a difference in the weight of each person?
A
applied
B
gravitational
C
normal
D
tension
The force is different because of the amount of weight applied so the answer is A
The force that makes a difference in the weight of each person is Gravitational. Correct option is B.
Gravitational force is a fundamental force of nature that exists between any two objects with mass. It's the force that keeps us and everything else on Earth anchored to its surface. This force is proportional to the mass of the objects involved and inversely proportional to the square of the distance between them.
For example, if you were standing on a bathroom scale, the reading on the scale represents the force of the Earth's gravity acting on your body, which is why it's often referred to as your "weight." The actual mass of an object remains constant regardless of its location, but its weight can vary depending on the strength of the gravitational field at different locations (e.g., the weight on the Moon would be less than on Earth due to the Moon's weaker gravitational pull).

How does a balanced chemical equation demonstrate the Law of Conservation of Mass?
Answer:
It shows the same number of atoms of each element on both sides of the equation
A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
Explanation:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
A balanced chemical equation shows that total number of atoms before reaction is equal to total number of atoms after the reaction. As, the total mass of any object lies on its atom, a balanced chemical equation demonstrate the Law of Conservation of Mass.
What is Dalton's atomic theory?The Dalton's atomic theory is as follows:
Atoms are the incredibly minuscule building blocks of all stuff.A given element's atoms are all the same size, mass, and other characteristics. Distinct elements' atoms have different mass, size, and other characteristics.Atoms can never be divided, produced, or eliminated.Chemical compounds can be created by combining atoms of various elements in straightforward whole number ratios.Atoms can be joined together, split apart, or altered during chemical processes.The total number of atoms before and after a reaction are equal, according to a chemical equation that is in balance. A balanced chemical equation illustrates the Law of Conservation of Mass since every object's atom holds the entirety of its mass.

Answer:
This section assumes you have enough background in calculus to be familiar with integration. In Instantaneous Velocity and Speed and Average and Instantaneous Acceleration we introduced the kinematic functions of velocity and acceleration using the derivative. By taking the derivative of the position function we found the velocity function, and likewise by taking the derivative of the velocity function we found the acceleration function. Using integral calculus, we can work backward and calculate the velocity function from the acceleration function, and the position function from the velocity function.Explanation:

If the activity of a source is 70 Bq after 2 years, and 35 Bq after 15 years. How long will be until the activity is 8.75 Bq?
Answer:
N = N0 e^-kt calling k the decay constant
70 = N0 e^-2 kt
35 = N0 e^-15 k
2 = e^(-2 + 15) k
.693 = 13 k
k = .0533
N0 = N e^kt
N0 = 70 e^(.0533 * 2) = 77.87
8.75 = 77.87 e^-(.0533 t)
ln .1124 = -.0533 t
t = -ln .1124 / .0533 = 41 yr
