Messages travel to and from the brain to other parts of the body through the spinal cord. Thus, brain and spinal cord works together and option A is the correct answer.
How does the brain and spinal cord work together?The spinal nerves connect the brain to the nerves in the major part of the body. Other nerves connect the brain to the eyes, ears, and other parts of the head directly. This network of nerves relays messages between the brain and the rest of the body.
The brain and spinal cord comprise the central nervous system. The brain is in charge of how we think, learn, move, and feel. The spinal cord relays messages from the brain to the nerves that run throughout the body.
Therefore, brain and spinal cord works together as messages travel to and from the brain to other parts of the body through the spinal cord.

as velocity _________ kinetic energy ____________ and potential energy _____________
Answer:
Kinetic energy increases and potential energy decreases
Explanation:
Because kinetic energy is proportional to the square of the velocity, when velocity is doubled, kinetic energy is quadrupled. Kinetic energy K=mv^2/2. Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
The simple activities like walking, jumping and falling involves kinetic energy. Here as the velocity increases kinetic energy increases and the potential energy decreases.
What is kinetic energy?The measure of the work that an object does by virtue of its motion is known as the kinetic energy. It is transformed between the objects and can be transformed into other forms of energy. It is a scalar quantity.
Every moving object and particle have kinetic energy. The kinetic energy of the particle is dependent on the mass and velocity of the particle. If the velocity is doubled, then the kinetic energy is quadrupled.
The equation of kinetic energy is:
Kinetic energy = 1/2 × m × v²
The energy stored by an object due to its position is called the potential energy. It is found to be maximum at a particular height. So it decreases with the increase of velocity.

You swing your golf club such that it hits a ball with a force of 15 newtons. It makes contact with the ball for a distance of 0.01 m. What is the work on the ball?
Answer:
W = 0.15 J
Explanation:
Given that,
The force acting on the ball, F = 15 N
It makes contact with the ball for a distance of 0.01 m
We need to find the work done on the ball. The work done can be calculated as :
W = Fd
So,
W = (15 × 0.01) J
W = 0.15 J
So, the work done is 0.15 J.

Write down three facts you about motion
Write Them in complete sentences
Answer:
Kindly check explanation
Explanation:
Motion of an object could be explainwd as how a body changes position over time. Some of the proven facts about motion are stated by Sor Isaac Newton, named the Laws of motion :
1. A body will continue on it's state of rest or uniform motion in a straight line unless acted upon by a force to make it act otherwise.
2.) The second law explains that the force acting in an object is a product of the mass and acceleration.
Force = mass * acceleration due to gravity
3.) To every action, there is an equal and opposite reaction.
That is ; applied force in the positive direction on an object, yield an equal amount of force in the opposite direction.

Conservation of momentum
Answer:
8.6 m/s
Explanation:
From the question,
applying law of conservation of momentum
Total momentum before collision = Total momentum after collsion
mu+m'u' = mv+m'v'....................... Equation 1
make v' the susbject of the equation
v' = (mu+m'u'-mv)/m'.................. Euqation 2
Where m = mass of the ball, m' = mass of the can, u = initial velocity of the ball, u' = initial velocity of the can, v = Final velocity of the ball, v' = final velocity of the can.
Given: m = 1.2 kg, m' = 0.7 kg, u = 14 m/s , u' = 0 m/s (at rest), v = 9 m/s.
Substitute these values into equation 2
v' = [(1.2×14)+(0.7×0)-(1.2×9)]/0.7
v' = (16.8-10.8)/0.7
v' = 6/0.7
v' = 8.6 m/s

Electrons are negatively charged and are deflected on a curving path towards the positive plate. Neutrons have no charge, and continue on in a straight line.
The particle will be deflected toward the positive plate as it enters the electric field is an electron.
What is an Electric field?The electric field is the region of space in which the particle experiences the electrostatic force.
As the plate is positive, so to deflect any particle towards it, the particle must be negatively charged.
An electron is a particle that has a negative charge.

When does a metal atom stop reacting
Answer:
When a metal element reacts with a non-metal element an ionic compound is formed. An understanding of the way the elements are bonded allows us to explain their typical properties.
Reactions between metals and non-metals include:
sodium + chlorine → sodium chloride
magnesium + oxygen → magnesium oxide
calcium + chlorine → calcium chloride
Explanation:
In all of these reactions, the metal atoms give electrons to the non-metal atoms. The metal atoms become positive ions and the non-metal atoms become negative ions.
A metal atom often stop reacting when it has lost all of its outer electrons.
Metal atoms often have few electrons in their outer shell.
Non-metal atoms does have plenty of electrons in their outer shell.
A Metal atoms lose the electron, or electrons, when in their highest energy level and tend to be positively charged ions.
Non-metal atoms often gain an electron, or electrons, so as to be negatively charged ions.
The loss or gain of valence electrons make ions to work with the octet rule and become more stable.

A tuba creates a 4th harmonic of
frequency 116.5 Hz. When the first
valve is pushed, it opens an extra bit
of tubing 0.721 m long. What is the
new frequency of the 4th harmonic?
(Hint Find the original length.)
(Speed of sound = 343 m/s)
(Unit = Hz)
Answer:
93.54 Hz
Explanation:
✓From the question, Number of harmonic frequency is 4
✓ the frequency (f₄ )= 116.5 Hz
✓harmonic frequency can be calculated using below expresion
fₙ = [ (nv)/4L]..........eqn(1)
v = speed of sound= 343 m/s
n = number of given harmonic frequency
L = Length of the rope
Using above expresion ,and substitute the values at (n=4) which is 4th harmonic frequency to find the " initial Lenght of the rope
fₙ = [ (nv)/4L]
f₄ = 4× 343 /4L
f₄ = 343 /L
L= 343 /f₄
But f₄= 116.5 Hz
L= 343/116.5= 2.944m
Hence, initial Lenght of the rope= 2.944m
We can determine the frequency of new length as ( initial Lenght of the rope + tubing Lenght)
= ( 2.944m + 0.721m )
= 3.667m
Hence, new length= 3.667m
To find the new frequency of the 4th harmonic we will use eqn(2)
f₄ = v/l ...............eqn(2)
From equation (2) If we substitute the values we have
f₄ = (343/3.667)
= 93.54 Hz
Hence, the the new frequency of the 4th harmonic is
93.54 Hz

The crane pull up the mass with 1150 N. Find the acceleration the
mass.m = 100kg
Kren tersebut menarik naik jisim itu dengan 1150 N. Cari daya
paduan pada jisim itu
[use gravitational acceleration, g = 9.81 m s?]
Answer:
-1.69 m/s²
Explanation:
We are told the crane pulls up the mass with a force of 1150 N.
This means it is in an opposite direction to gravity and thus acceleration(a) is negative.
Now, the gravity is acting downwards, thus, total force is;
F = mg - ma
1150 = 100(9.81 - a)
Divide both sides by 100 to get;
11.5 = 9.81 - a
a = 9.81 - 11.5
a = -1.69 m/s²
a. l1 =20 A and l2 =24 A
B. l1 = 20A and l2 = 12 A
C. l1 = 26 A and l2 = 12 A
D. l1 = 24 A and l2 = 8 A
