Freud was an influential and controversial psychologist who believed that psychology should study the unconscious mind. Describe
the two books Freud published in the early 1900s. (Site 2)
Answer:
The Interpretation of Dreams": Freud noticed that dreams played an important role in his analysis of neurotic and "hysterical" patients. When he asked his patients to talk about whatever came into their minds, they often referred to their dreams, which would set off other associations and often illuminate other important connections in their past experience. It took Freud about two years to write the book, finishing it in September 1897.

why does the light of black body radiation change
The wavelength at which the radiation is strongest is given by Wien's displacement law, and the overall power emitted per unit area is given by the Stefan–Boltzmann law. So, as temperature increases, the glow color changes from red to yellow to white to blue.
a spacecraft that seems to be motionless in deep space is given some type of quick push. which statement describes what will happen?
An applied force applied causes a body such as the spacecraft to move. The magnitude of the force determines the change in the velocity
What will happen to the spacecraft is given by option C. from among the possible question options.
C. The spacecraft will begin to move and it will continue moving until it is stopped by an equal and opposite force
Reason:
The possible question options obtained from a similar question includes;
A. The spacecraft will move for some time then stop slowly
B. Air resistance will prevent the spacecraft from moving
C. The spacecraft will begin to move and the motion will continue until a force equal and opposite to the applied force stops it
D. The quick push will not cause the spacecraft to move, as a quick push works on Earth only
The state of the space craft = Motionless
Location of the spacecraft = Deep space
Type of force applied = Quick push
The statement that describes what will happen = Required
Solution;
Let F, represent the force applied, and let Δt be the duration of the applied force, we have;
The impulse of the force, F × Δt = m·(v₂ - v₁)
Where;
m = The mass of the spacecraft
v₁ = The initial velocity of the spacecraft = 0
v₂ = Final velocity of the spacecraft
Plugging in v₁ = 0, gives;
F × Δt = m·v₂
The space craft is given a velocity, v₂, and according to Newton's First Law of Motion, it continues moving in a straight line until another force acts on it
Therefore, the correct option is option C. The spacecraft will begin to move and the motion will continue until it is stopped by an equal and opposite force

a marble rolls horizontally off a table that is 0.8m tall. if the marble lands 0.6m from the base of the table, what is the initial velocity of the marble?
The initial velocity of the marble from the given position is 1.49 m/s.
The given parameters;
height of the table, h = 0.8 mhorizontal distance traveled by the train, X = 0.6 mThe time of motion of the marble from the given height is calculated as;
[tex]h = v_yt + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 0.8}{9.8} }\\\\t = 0.404 \ s[/tex]
The initial horizontal velocity of the marble is calculated as follows;
[tex]X = v_0_xt\\\\v_0_x = \frac{X}{t} \\\\v_0_x = \frac{0.6}{0.404} \\\\v_0_x = 1.49 \ m/s[/tex]
Thus, the initial velocity of the marble from the given position is 1.49 m/s.

A worker pushes a box across the floor to the right at a constant speed with a force of 25N. What can you conclude about the box?
A. An unbalanced force of 25N is acting on the box.
B. The net horizontal force acting on the box is 50N.
C. Friction between the box and the floor is 25N to the left.
D. Friction between the box and the floor is 25N to the right.
Answer:
C. Friction between the box and the floor is 25N to the left
Explanation:
Answer:
Since the forces exerted on the box are equal and opposite in direction, the net force will be 0, so the box will not move.

A. There is positive net force.
B. There is negative net force.
C. The net force is zero.
D. There is a small net force.
Answer:
B I'm Pretty Sure :DDD
Explanation:
Balanced Forces
In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. You observed that the object did not move. When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.
Which situations might cause two observers (A and B) to measure different frequencies for the same vibrating object? Select the two correct answers.
A. Observer A is stationary and Observer B is moving.
B. Observer A and Observer B are moving at different speeds relative to each other.
C. Observer A and Observer B are stationary but at different distances from the vibrating object.
D. Observer A and Observer B are both stationary and at the same distance from the object.
Answer: The answer is (B) Observer A and Observer B are moving at different speeds relative to each other. And (A) Observer A is stationary and Observer B is moving
Explanation:
This question involves the concept of doppler's effect and its effect on the frequency of sound.
The situations that might cause the two observers to measure different frequencies for the same vibrating object are:
"A. Observer A is stationary and Observer B is moving.
B. Observer A and Observer B are moving at different speeds relative to each other."
Doppler's effect states that the apparent frequency of a source of sound is different than its original frequency. It further explains that whenever an observer and the source are in relative motion with each other, either the source or the observer or both are moving, then the frequency of sound measured by the observer will be different than the actual frequency. This changed frequency is called the apparent frequency and it depends upon the direction and magnitude of the relative motion of the observer and the source.
Hence, the measured frequency can be different for the two observers if they are in relative motion with the source, with different speeds, or in the case when one observer is stationary while the other is in motion.
Therefore, the situations that might cause the two observers to measure different frequencies for the same vibrating object are:
A. Observer A is stationary and Observer B is moving.
B. Observer A and Observer B are moving at different speeds relative to each other.

b) In order to accelerate an object more, one would need to apply_more____ force.
c) If an equal force is applied to two different objects, the less massive object will accelerate_more___
The answer is less, more and more.
Relationship between mass and accelerationIf an object has more mass than another object, it will accelerate less. In order to accelerate an object more, one would need to apply more force. If an equal force is applied to two different objects, the less mass of an object will accelerate more
The acceleration of an object depends directly on the force acting upon the object, and inversely on the mass of the object.

Write down the relation between force pressure and area
Answer:
Answer: Pressure is directly proportional to force and inversely proportional to area.
Explanation: Pressure is defined as the ratio of force applied to the area of cross section.
Mathematically,
P=\frac{F}{A}P=
A
F
where,
P = Pressure
F = Force applied
A = Area of cross-section
from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.
The units of pressure are N/m^2N/m
2
and S.I. units for this term is Pascal (P).
