The concept of "magnetism animal" implied that every person has a raw, magnetic energy. Hence option C is correct.
What is magnetic energy?Magnetic energy is defined as the shifting of the electrons' charge in various particles. Magnetism is the force that magnets employ to either attract or repel one another. Electric charges in motion are what generate magnetism.
Supposedly invisible or mysterious energy known as "animal magnetism" is claimed to affect people. Franz Mesmer, a German physician, used the term "animal magnetism," also known as mesmerism, to describe what he believed to be an innate natural power that all living things, including people, animals, and plants, had.
Thus, the concept of "magnetism animal" implied that every person has a raw, magnetic energy. Hence option C is correct.

What is meant by the term total internal reflection? What two conditions must be met for total internal reflection to occur?
Answer:
Hello....
Explanation:
Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
The conditions required for total internal reflection (TIR) to occur are:
1)the light must be travelling from a more dense medium into a less dense medium (ie glass to air)
2)the angle of incidence must be greater than the critical angle.

-5.22 m/s^2
-27.6 m/s^2
-0.19 m/s^2
O 0.19 m/s^2
Answer:
5.22 m/s²
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 2.3 s
Acceleration (a) =.?
Acceleration is defined as the change of velocity with time. Mathematically, it is expressed as:
Acceleration (a) = final velocity (v) – initial velocity (u) / time (t)
a = (v – u) /t
With the above formula, we can obtain the acceleration of the racehorse as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 2.3 s
Acceleration (a) =.?
a = (v – u) /t
a = (12 – 0) / 2.3
a = 12 /2.3
a = 5.22 m/s²
Therefore, the average acceleration of the racehorse is 5.22 m/s²

The Touch sensory system is made up of sense receptors which carry the information to be sent to the Central nervous system which the brain and the spinal cord is an essential part
Which of the following is an accurate description of synaptic pruning?
Answer options:
A) Some connections are lost because critical stages of development were missed.
B) Some connections are lost so others can be strengthened.
C) Some connections are lost because of experimentation with drugs or alcohol.
D) Some connections are lost so that children become less dependent and are less tied to their parents.
Answer:
B) Some connections are lost so others can be strengthened.
Explanation:
Synaptic pruning refers to a natural process that occurs in the brain between childhood and adulthood. Extra synaptic connections are eliminated in order to increase the efficiency of neuronal communications. It is thought to be the brain’s way of removing connections that are no longer needed.

How do streams flow?
Answer: When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. As small creeks flow downhill they merge to form larger streams and rivers. Rivers eventually end up flowing into the oceans.
Explanation:
velocity is derived physical quantity why
Answer:
Velocity is “how much distance you cover in a particular time.” Space and time are fundamental quantities, and meters and seconds are their base units. Velocity is a combination of a space and a time, and therefore its units — “m/s” – are “derived” from the units for space and time

The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.
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.
Every action has an equal and opposite response, according to Newton's Third Law. Burning fuel in a rocket causes a push that propels the rocket forward from the front. As a result, the exhaust gas is pushed in the opposite direction and equally.
The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.

Kinematics
29. A car starts from rest and attains a velocity
of 40 m/s in 20 s. It maintains this velocity
for 30 s and then comes to rest in 25 s.
Calculate
a) the acceleration of the car;
b) the deceleration of the car,
c) the total distance covered by the car.
Answer:
a)
a = 2 [m/s^2]
b)
a = 1.6 [m/s^2]
c)
xt = 2100 [m]
Explanation:
In order to solve this problem we must use kinematics equations. But first we must identify what kind of movement is being studied.
a)
When the car moves from rest to 40 [m/s] by 20 [s], it has a uniformly accelerated movement, in this way we can calculate the acceleration by means of the following equation:
[tex]v_{f} = v_{i}+(a*t)[/tex]
where:
Vf = final velocity = 40 [m/s]
Vi = initial velocity = 0 (starting from rest)
a = acceleration [m/s^2]
t = time = 20 [s]
40 = 0 + (a*20)
a = 2 [m/s^2]
The distance can be calculates as follows:
[tex]v_{f} ^{2} = v_{i} ^{2}+(2*a*x)[/tex]
where:
x1 = distance [m]
40^2 = 0 + (2*2*x1)
x1 = 400 [m]
Now the car maintains its speed of 40 [m/s] for 30 seconds, we must calculate the distance x2 by means of the following equation, it is important to emphasize that this movement is at a constant speed.
v = x2/t2
where:
x2 = distance [m]
t2 = 30 [s]
x2 = 40*30
x2 = 1200 [m]
b)
Immediately after a change of speed occurs, such that the previous final speed becomes the initial speed, the new Final speed corresponds to zero, since the car stops completely.
[tex]v_{f} = v_{i}-a*t[/tex]
Note: the negative sign of the equation means that the car is stopping, i.e. slowing down.
0 = 40 - (a *25)
a = 40/25
a = 1.6 [m/s^2]
The distance can be calculates as follows:
[tex]v_{f} ^{2} = v_{i} ^{2} -2*a*x3\\[/tex]
0 = (40^2) - (2*1.6*x3)
x3 = 500 [m]
c)
Now we sum all the distances calculated:
xt = x1 + x2 + x3
xt = 400 + 1200 + 500
xt = 2100 [m]

A force of 500 N acts for a time interval of 0.001 second on an object of mass 0.20 kg that was initially at rest. Calculate the final velocity of the object after the force acts
Answer:
100
Explanation:
The final velocity of the object after the force acts is 2.5 meters per second.
To calculate the final velocity of the object after the force acts, we can use Newton's second law of motion, which states that:
Force = Mass × Acceleration
We need to find the acceleration of the object first. Since the object was initially at rest, its initial velocity (u) is 0 m/s.
The force acting on the object is 500 N, and the mass of the object is 0.20 kg. We can rearrange the equation to find the acceleration (a):
Acceleration (a) = Force / Mass
a = 500 N / 0.20 kg
a = 2500 m/s²
Now, we can use the kinematic equation to find the final velocity (v) of the object:
Final velocity (v) = Initial velocity (u) + (Acceleration × Time)
The initial velocity (u) is 0 m/s (since the object was initially at rest), and the time interval (t) is 0.001 second.
Final velocity (v) = 0 m/s + (2500 m/s² × 0.001 s)
v = 0 m/s + 2.5 m/s
v = 2.5 m/s
Hence, the final velocity of the object after the force acts is 2.5 meters per second.
