The ability of people to grow personally is highlighted by the humanistic psychology viewpoint.
In opposition to psychoanalytic theory and behaviorism, the humanistic perspective gained popularity in the middle of the 20th century. It highlights how healthy people develop and a person's innate desire for self-actualization and creativity. The humanistic perspective seeks to understand a person as a complete rather than just via one particular component of their personality. It is a subfield of psychology that deals with the notion of being wholly original and distinctive. A school of thought or philosophy known as "psychological perspective" is one that would help someone comprehend someone else's conduct.

Newton's laws of motion
Answer:second law
Acceleration of an object depends on the mass of the object and the amount of force applied
Which equation can be used to solve for acceleration?
t=v/a
vf=at-vi
a=d/t
v=a/t
Answer:
t=v/a
Explanation:
Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
The change in velocity per unit of time is the acceleration
From this equation;
time = [tex]\frac{change in velocity }{acceleration}[/tex]
This expression is analogous to the expression chosen.

a 87 kg block is pulled across the table by the horizontal force of 43N with a fictional force of 7.3 opposing the motion calculate the acceleration of the object
Answer:
a = 0.41 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = force [N]
m = mass = 87 [kg]
a = acceleration [m/s²]
The frictional force will be taken as negative, since it opposes the movement of the block.
[tex]43-7.3 = 87*a\\35.7 = 87*a\\a=0.41[m/s^{2} ][/tex]
A car starts from rest and accelerates at 4 m/s2 until it reaches 36 m/s. How far did it travel in this time?
The distance of a car that starts from rest and accelerates at 4 m/s² until it reaches 36 m/s is 162m.
How to calculate distance?The distance moved by a body can be calculated using the following formula:
S = ut + ½at²
Where;
S = distanceu = initial velocityt = timea = accelerationHowever, the time taken for the car to complete the acceleration can be calculated as follows:
4 = 36/t
t = 9seconds
S = 0 × t + ½ × 4 × 9²

two skateboarders of mass 50 kg and 60 kg push each other with force 70N.what is the acceleration of each skaters
Answer:
0 m/s²
Explanation:
Since each skater pushes the other with a force of 70 N, according to Newton's third law, there is an equal reaction and thus the other pushes back with a force of 70 N in the other direction, so we have forces of +70N and -70 N respectively. So, the net force on each skateboarder is F = + 70 N + (-70 N) = + 70 N - 70 N = 0 N.
Since force, F = ma where a = acceleration and m = mass,
a = F/m.
So, since for each skater, F = 0N,
a = 0 N/m
= 0 m/s²
So, the acceleration of each skater is 0 m/s²

At extreme position, velocity is zero but acceleration is maximum in SHM.how can you theoretically explain it?
At extreme position, velocity is zero but acceleration is maximum in Simple Harmonic motion because of maximum displacement of pendulum.
Why acceleration is maximum when velocity is zero in SHM?At extreme position, velocity is zero but acceleration is maximum in Simple Harmonic motion because at extreme points the motion of the pendulum is at zero which means that velocity is zero but the pendulum attains maximum displacement. Acceleration is maximum when it gets the extreme position because the displacement is maximum at extreme position. If the velocity of the simple harmonic motion is maximum, the acceleration must be equal to zero and we know that the acceleration is equal to zero only when the particle or object is at initial position.
So we can conclude that at extreme position, velocity is zero but acceleration is maximum in Simple Harmonic motion because of maximum displacement of pendulum.

An earthquake can produce a seiche in a lake in which the water sloshes back and forth from end to end with remarkably large amplitude and long period. Consider a seiche produced in a farm pond. Suppose the pond is 9.15 m long and assume it has a uniform width and depth. You measure that a pulse produced at one end reaches the other end in 2.50s. (b) What should be the frequency of the ground motion during the earthquake to produce a seiche that is a standing wave with antinodes at each end of the pond and one node at the center?
The frequency of the ground motion is 0.2 Hz
What should be the frequency of the ground motion during the earthquake to produce a seiche that is a standing wave with antinodes at each end of the pond and one node at the center?The frequency of the ground motion f = 1/T where T = period of ground motion.
Now, the pond is 9.15 m long and assume it has a uniform width and depth. You measure that a pulse produced at one end reaches the other end in 2.50s.
Since this is a standing wave with antinodes at each end of the pond and one node at the center, we have that the distance between two antinodes is half the wavelength.
Also, the time between two antinodes is half the period.
So, t = T/2
Now, since a pulse produced at one end reaches the other end in 2.50s, this is the time between both antinodes.
So, the period, T = 2t where t = time between antinodes = 2.50 s
So, T = 2t
= 2 × 2.50 s
= 5.0 s
Since the frequency of the ground motion f = 1/T substituting the value of T into f,we have
f = 1/T
= 1/5.0 s
= 0.2 Hz
So, the frequency of the ground motion is 0.2 Hz

Explain cylindrical symmetry?A surface or solid of revolution exhibits circular symmetry around an axis in three dimensions. This property is also known as cylindrical symmetry or axial symmetry.
Apply Ampere's law to the circle in the image with the number 1 on it. The magnetic field inside the tube must be zero because the current has a cylindrical symmetry about its central axis, which causes the line integral to reduce to the magnetic field's strength times the path's circumference.
However, this is equal to zero because there is no current flowing along this path. On the other hand, if the conductor's current is the current flowing through channel 2, the line integral will not equal zero, indicating that there is a magnetic field outside the tube.
