What is noetic science?
Noetic science is an interdisciplinary field that aims to understand consciousness and the human mind. It stems from the Greek word 'noesis' which means inner wisdom, direct knowing, or subjective understanding. It shares some principles with physics, particularly quantum physics, but also extends beyond traditional physics to explore consciousness and subjective experiences.
Explanation:Noetic science, which also aligns with concepts in cognitive science, is an interdisciplinary field that seeks to understand the nature of consciousness and the human mind. It looks into the capabilities of the mind beyond the physical realm and tries to understand phenomena like cognition and intuition.
The terms noetic science comes from the Greek word "noesis" which means inner wisdom, direct knowing, or subjective understanding. In essence, it is about investigating the nature of consciousness, going a step beyond the traditional physical sciences.
It explores the idea that consciousness isn't solely a product of the brain and attempts to bridge the gap between the objective sciences and the inner subjective experience. This would indeed fall under the wider umbrella of physics as it deals with aspects of energy and matter.
It shares some principles with physics, specifically quantum physics, in the sense that it investigates the fundamental nature of the universe and the interactions of energy and matter. However, it extends these investigations to encompass consciousness and subjective experiences which are more difficult to quantify and measure.

Object A has of mass 7.20 kilograms, and object B has a mass of 5.75 kilograms. The two objects move along a straight line toward each other with velocities +2.00 meters/second and -1.30 meters/second respectively. What is the total kinetic energy of the objects after the collision, if the collision is perfectly elastic?
A.
19.3 joules
B.
21.9 joules
C.
38.5 joules
D.
43.0 joules
E.
50.8 joules
Answer:
A. 19.3 joules
Explanation:
The collisions is perfectly elastic: this means that both total momentum and total kinetic energy are conserved after the collision.
Therefore, we can just calculate the total initial kinetic energy before the collision, and then say that it is equal to the total kinetic energy after the collision.
The kinetic energy of object A is:
[tex]K_A = \frac{1}{2}m_A v_A^2=\frac{1}{2}(7.2 kg)(+2.0 m/s)^2=14.4 J[/tex]
The kinetic energy of object B is:
[tex]K_B = \frac{1}{2}m_B v_B^2=\frac{1}{2}(5.75 kg)(-1.3 m/s)^2=4.9 J[/tex]
So, the total kinetic energy before (and after) the collision is
[tex]K=K_A + K_B=14.4 J+4.9 J=19.3 J[/tex]
if an object is moving at a constant speed, the forces acting on it must be ___. Another way to say this is that the net force = __.
Answer : Equal, Zero
If the object is moving at constant speed, it is under "equilibrium". So, forces acting on object are equal and the net force is zero.
Suppose you are pushing a car with a certain net force. If you then push it twice the net force, the car's acceleration

In a cricket match, the 0.16kg ball is bowled with a straight arm. During one particular delivery, the ball leaves the bowler's hand horizontally, with a speed relative to the ground of 80.8 mph. The bowler's arm is 0.64 m long and the bowler is running at 10.0 mph when the ball is released.
Calculate the centripetal force exerted on the ball in the bowler's hand, in N.
Note: 1 mph = 0.447 ms^-1.
Answer:
412.1 N
Explanation:
First of all let's calculate the total speed of the ball as it is released, which is equal to the speed of the ball + the speed of the bowler:
[tex]v=80.8 mph +10.0 mph=90.8 mph[/tex]
Now let's convert it into m/s. We know that
[tex]1 mph = 0.447 m/s[/tex]
So
[tex]1 mph:0.447 m/s = 90.8 mph:v\\v=\frac{(0.447 m/s)(90.8 mph)}{1 mph}=40.6 m/s[/tex]
And now we can calculate the centripetal force, which is given by:
[tex]F=m\frac{v^2}{r}[/tex]
where
m = 0.16 kg is the mass of the ball
v = 40.6 m/s is the speed of the ball
r = 0.64 m is the radius of the circular path (equal to the length of the bowler's arm)
Substituting:
[tex]F=(0.16 kg)\frac{(40.6 m/s)^2}{0.64 m}=412.1 N[/tex]

= 265 Kg (Neglect negetive sign)
Mass of the car is 265 Kg
If an object weighs 300 N on earth, what is it’s mass on the moon?
Answer:
The mass of the object on the Moon (and anywhere else) is about 30.61kg. Please see more detail below.
Explanation:
Weight is the gravitational force exerted on the object and is a function of mass and gravitational acceleration:
(weight) = (mass) x (gravitational acceleration)
We are to find the mass, knowing the weight on Earth to be 300N:
(mass) = (weight on Earth) / (gravitational acceleration on Earth) = 300N / 9.8 m/s^2 = 30.61 kg
The mass of the object is 30.61kg.
The mass of the object is independent of gravity. Therefore the answer to the question "What is its mass on the Moon" is 30.61kg.
If the question were what is its weight on the Moon, the answer would be
(weight on Moon) = (mass) x (grav.accel. on Moon) = 30.61kg x 1.62 m/s^2 = 49.59N
which is about 1/6 of the object's weight on the Earth.

Given that,
Capacity = 3.6 gallons per minutes
Convert it into milliliters per seconds
Since, 1 gallon = 3.79 liters
1 liters = 1000 milliliters
Capacity= (3.6*3.79*1000)/(60)
Capacity = 227.4 milliliters per second.
3.6 gallons per minute is equivalent to a flow rate of 227.4 milliliters per second.
Here are the steps to convert 3.6 gallons per minute to milliliters per second:
Convert gallons to liters: 3.6 gallons * 3.79 liters/gallon = 13.644 liters per minute.
Convert minutes to seconds: Since there are 60 seconds in a minute, divide 13.644 liters by 60 to get the flow rate in liters per second: 13.644 liters / 60 seconds = 0.2274 liters per second.
Convert liters to milliliters: Since there are 1,000 milliliters in a liter, multiply 0.2274 liters by 1,000 to get the flow rate in milliliters per second: 0.2274 liters * 1,000 milliliters/liter = 227.4 milliliters per second.
Therefore, 3.6 gallons per minute is equivalent to 227.4 milliliters per second.

A frame hanging on a wall is held by two cables. The tension in each cable is 30 N, and the cables make an angle of 45° with the horizontal, as shown in the picture. What is the weight of the frame?
A) 10.2 N
B) 21.2 N
C) 32.4 N
D) 42.4 N
Answer: This is wrong The correct answer is 42.4 N
Explanation: I took the USA TESTPREP
OPTION D. The weight of the frame is determined by the upward force the two cables exert to keep it in equilibrium. Each cable exerts a vertical force of 21.2 N, totaling to 42.4 N. Thereby, the weight of the frame is 42.4 N.
Explanation:This problem can be solved using the principle of forces in equilibrium. If the frame is at rest and not falling, the resultant force is zero, meaning the upward forces equal the downward forces. The tension force in the cable has components parallel and perpendicular to the direction of gravity. We only need to consider the vertical component as that is the direction of the weight of the frame.
The vertical component of the tension in one cable is given by Tsinθ = 30N * sin(45°) = 21.2 N. Since there are two cables, the total upward force is 2 * 21.2 N = 42.4 N. This equals the downward force, i.e. the weight of the frame, which is therefore 42.4 N. So, the correct answer is D).

How do you know that potassium an alkali metal is highly reactive
Potassium is in the most reactive group of elements, the alkali metals, but it's not the most reactive metal within the group. The alkali metals, Group 1A, are the most reactive metals because they have one valence or outer electron. They lose this electron very easily, forming ions with a charge of +1.
Potassium is known as a highly reactive alkali metal due to its small ionization energy that facilitates the loss of its valence electron to form K+ ions. Its extreme reactivity is also demonstrated when it reacts with oxygen, water, and halogens, often requiring it to be stored under oil to prevent accidental reactions with air or moisture.
We know that potassium is a highly reactive alkali metal due to several characteristics. One of the key reasons for its reactivity is its small ionization energy, which makes it easier for potassium to lose its single outer-shell electron and form [tex]K^+[/tex] ions. This low ionization energy is common among alkali metals, and it allows them to form monocations easily.
Potassium's reactivity is also evident as it must be stored under oil to prevent it from reacting with air. When potassium does react with air, especially oxygen, it can cause a combination reaction that is highly exothermic. A balanced chemical equation representing this reaction with oxygen is [tex]4K + O_2 \rightarrow 2K_2O[/tex].
Furthermore, the reactivity of potassium can be seen when it is placed in water. The reaction is intense enough to produce hydrogen gas and heat, with heavier alkali metals reacting even more violently. The typical reaction with water is shown by the equation [tex]2K + 2H_2O \rightarrow 2KOH + H_2[/tex]. Finally, potassium's reactivity is demonstrated in its reactions with halogens, which are typically very exothermic and even violent.

what are the units for the spring constant,k?
Answer:
[tex]\frac{kg}{s^2}[/tex] or [tex]\frac{N}{m}[/tex]
Explanation:
The force in a spring is described as (F) = (k) x (d) with (d) being the displacement, measured in meters. (F) is to come out in Newtons. So (k) is assigned the appropriate unit for that to happen. The two possibilities listed above achieve that.
Answer:
The units for the spring constant k is [tex]\frac{kg}{s^2}\ \text{or}\ \frac{N}{m}[/tex].
Explanation:
According to hooks law:
[tex]F=-kx[/tex]
Where F is a force, k is spring constant and x is distance.
Here, the negative sign of the force of the spring, which implies the force of the spring, is opposed to the displacement of the spring.
Now in order to find the units for spring constant k, ignore the negative sign as we are looking only at the magnitude.
[tex]F=kx[/tex]
[tex]\frac{F}{x}=k[/tex]
Therefore,
[tex]\frac{kg}{s^2}\ \text{or}\ \frac{N}{m}[/tex]
Hence, the units for the spring constant k is [tex]\frac{kg}{s^2}\ \text{or}\ \frac{N}{m}[/tex].

A truck travelled at a constant speed for 6 hours. Then , it decreased itd speed by 13 mph for the remaining 228 miles. If the total distance was 876 miles, how long did it take to travel the remaining 228 miles
Answer:
Time taken to travel remaining 228 miles = 2.4 hours.
Explanation:
Total distance = 876 miles.
Distance traveled after speed reduction = 228 miles
So, distance traveled before = 876 - 228 =648 miles.
Time taken for this = 6 hours.
Speed before speed reduction = 648/6 = 108 mph.
Speed after speed reduction = 108 - 13 = 95 mph
Time taken to travel remaining 228 miles = 228/95 = 2.4 hours.
