Abstract of American Intercontinental University
This paper will compare and contrast three of the 10 main early psychology views. This assignment's three approaches are behavioral, humanistic, and cognitive. Three Early Psychology Perspectives are compared and contrasted. Psychology, like anything else, offers a plethora of theories and methods. One idea may be beneficial to one patient while being ineffective to another. The trick is to discover the optimal method for each patient. The concept that behaviors arise as a result of conditioning is known as behaviorism. This theory does not acknowledge the presence of interior mental factors such as thoughts, feelings, and moods, nor does it take free will into account.

A 320.-kg reindeer stands in the middle of the railroad tracks, frozen by the lights of an oncoming 10,000.-kg train that is traveling at 10.0 m/s. The engineer sees the reindeer but is unable to stop the train in time and the reindeer rides down the track sitting on the cowcatcher. What is the new combined velocity of the reindeer and train?
Answer:
9.69 m/s
Explanation
By the conservation of momentum, we can write the following equation:
[tex]\begin{gathered} p_i=p_f \\ m_1v_{i1}+m_2v_{i2}=(m_1+m_2)v_f \end{gathered}[/tex]Where m1 is the mass of the reindeer, m2 is the mass of the train, vi1 is the initial velocity of the reindeer, vi2 is the initial velocity of the train and vf is the final velocity of the reindeer and train.
So, replacing m1 = 320 kg, m2 = 10,000 kg, vi1 = 0 m/s and vi2 = 10 m/s, we get
[tex]\begin{gathered} 320(0)+10,000(10)=(320+10000)v_f_{} \\ 0+100,000=(10320)v_f \\ 100,000=10,320v_f \end{gathered}[/tex]Now, solving for the final velocity, we get
[tex]\begin{gathered} v_f=\frac{100,000}{10,320} \\ v_f=9.69\text{ m/s} \end{gathered}[/tex]Therefore, the new combined velocity of the reindeer and train is 9.69 m/s

Let us substitute the value of r in the above equation,
V = 4/3 x 3.14 x (0.25)³
= 4/3 x 3.14 x 0.0156
= 0.196/3
V = 0.065 m³
So , now let us find the mass of the given sphere
ρ = m / v
m = ρv
m = 7860 x 0.065
m = 510.9 kg
Therefore , the mass of the given iron sphere is 510.9 kg

Cory is at the park playing fetch with his dog. He throws the ball 23 m south, and his dog retrieves the ball and returns it to Cory. Cory then throws the ball 18 meters, and the dog again collects the ball and returns it to Cory. When the dog returns for the second time, what distance has the dog traveled?0 m82 m36 m23 m
In order to determine the distance traveled by the dog in the two times, consider:
In the second time the dog goes and comes back for a distance of 18 m, that is, the total distance is 18m + 18m = 36 m
In the first time the dog goes and comes back for a distance of 23 m, that is, the total distance is 23m + 23m = 46 m
Hence, for the two times the distance traveled by the dog is:
46m + 36m = 82m
A block of mass M is hung by ropes as shown. The system is in
equilibrium. The point O represents the knot, the junction of the
three ropes. The angle theta is given to be 30o
. Which of the
following statements is true concerning the magnitudes of the three
forces in equilibrium?
Their magnitude of force must be the same for the tensions to equal out.
An object at equilibrium has zero acceleration so both the magnitude and direction of the object's velocity must be constant. When the body is in equilibrium the forces are balanced. Balanced is a keyword used to describe a balanced state. Therefore the net force is zero and the acceleration is 0 m/s/s. The acceleration of a body in equilibrium must be 0 m/s/s
For a body to be in equilibrium it must not be accelerating. This means that both the net force and net torque on the object must be zero. Clearly when in equilibrium, the net force on the object is zero. According to Newton's second law of motion if the net force is zero the acceleration is also zero. When the acceleration is zero the velocity and thus the velocity is constant by definition. Option d does not apply to equilibrium in this case.

A spherical specimen of the mineral chalcopyrite measures 3.9 cm in diameter and has a mass of
129.67 g. What is its specific gravity?
A spherical specimen of the mineral chalcopyrite measures 3.9 cm in diameter and has a mass of 129.67 g, its specific gravity is 4.17g/cm³
What is specific gravity?The ratio of a substance's density to that of a reference substance is its specific gravity, also known as relative density.
Water, which has a density of 1.0 kg/litre at 4 °C (39.2 °F), serves as the standard of comparison for solids and liquids (62.4 pounds per cubic foot).
Dry air, which is frequently used as a comparison point for gases, has a density of 1.29 grams per litre (1.29 ounces per cubic foot) under what are known as "standard conditions" (a temperature of 0 °C and a pressure of 1 standard atmosphere).
As an illustration, the specific gravity of liquid mercury is 13.6 due to its density of 13.6 kg per litre. The density of the gas carbon dioxide, which is 1.976 grams per liter under ideal conditions, translates into a specific gravity of 1.53 (= 1.976/1.29).
The formula for specific gravity is given by
specific gravity = density of the object / density of the water
Here given that a spherical specimen of the mineral chalcopyrite measures 3.9 cm in diameter and has a mass of 129.67 g
Then its volume is
Volume of sphere = [tex]{\frac {4}{3}}\pi r^{3}[/tex]
Substituting the values we get
V = [tex]{\frac {4}{3}}\pi (\frac{3.9}{2} )^{3}[/tex]
= 31.06 cm³
Density = Mass/Volume
Density of mineral chalcopyrite = 129.67g / 31.06 cm³
= 4.17 g/cm³
Now, we can finally calculate specific gravity
specific gravity = 4.17 g/cm³ / 1g/cm³ (Density of water is 1m/1V)

On a plot of angular position versus time t for the rotation of a disk, what corresponds to the disk’s angular velocity at any given instant t1?
a. inverse of the slope at the point on the plot corresponding to t1
b. intercept on the vertical axis
c. slope at the point on the plot corresponding to t1
d. intercept on the horizontal axis
Option d i.e; Slope at the point on the plot corresponding to t1 corresponds to disk's angular velocity at any given instant t1.
The angular velocity (w), a vector quantity in uniform circular motion, is determined by dividing the angular displacement (Δ), also a vector quantity, by the change in time (Δt). Speed is equal to |w|R and is calculated by dividing the arc length travelled (S) by the change in time (Δt).
Examples of angular velocity include a roulette ball on a wheel, a race car travelling in a circle, and a Ferris wheel. In addition, the object's angular displacement with respect to time is represented by the angular velocity of the object.
Because it is practical, angular velocity is perpendicular. Because all they are is a magnitude and a direction, a vector cannot be curved. In order to represent the rotational direction, we use the direction perpendicular to the plane.

1 atm = 1.01x 105 Pascals
The volume of the gas once it reaches the surface of water is 2 liters.
The volume of the air in balloon at depth of 100ft (30m) is 500ml.
The pressure at this point is 4 atm.
Assuming that the balloon have no compression by rubber of balloon the volume of air at the water surface is V.
The pressure at the surface of water is 1 atms.
As we know, from the ideal gas equation,
PV = nRT
Where,
P is the Pressure of gas,
V is the volume of the gas,
n is the number of moles,
R is the gas constant whose value is 0.082057 L atm mol-1 K-1,
T is the temperature.
Assuming that the temperature is constant,
We know,
PV = nRT
All quantities on the right side are constants,
So, we can write,
P₁V₁ = P₂V₂
Putting all the the values,

If the slope of a position versus time graph is negative, what does that imply about the motion of an object? A. The object has a negative acceleration. B. The object turned around. C. The object is moving in the negative direction. D. All of the above
ANSWER
A. The object has a negative velocity
EXPLANATION
We want to describe the slope of a position-time graph that is negative.
If the slope of a position-time graph is negative, it implies that the velocity is also negative. In other words, as time increases, the velocity also decreases.
As velocity decreases, it implies that the acceleration also decreases.
Therefore, we have that the acceleration of the object is negative.

Calculate the amount of charge that flows past a cross-sectional area of a conductor if a current of 0.2 A flows in it for 1 minute?
Answer:
12C
Explanation:
q = It
where q is the charge in coloumbs (c)
I is the current in amperes (A)
t is the time in seconds (s)
q = 0.2× 60 (1 minute is 60seconds)
q= 12C
