Answer:
You discuss your feelings and analyze your emotions.
Explanation:
During free association a therapist or psychoanalyst helps you discuss your feelings and analyze your emotions.
Free association allows patients to discuss their minds freely without any censorship. This helps people to communicate freely without placing any barrier on their free thought pattern. All the thoughts that comes to mind are encouraged to be expressed and spoken.Answer:
In traditional free association, a person in therapy is encouraged to verbalize or write all thoughts that come to mind. Free association is not a linear thought pattern. Rather, a person might produce an incoherent stream of words, such as dog, red, mother, and scoot. They may also jump randomly from one memory or emotion to another.

5. A baseball player bats a ball with a force of 1,000 N. The ball exerts a reaction force against the bat
of...
a. Less than 1,000 N
b. More than 1,000 N
c. 1,000 N
Why???
Explaining the concept:
Reaction force is the equal and opposite force applied by an object after we apply some force to it
This is explained in the Newton's Third Law of Motion, which says: "For every action, there is an equal and opposite reaction"
This means that any force we apply on an object, it applies the same force on us
Reaction Force exerted by the ball:
We now know what a reaction force is. Now looking at the scenario, we can see that the player applied a force of 1000N on the ball using his bat
The ball will also apply an equal and opposite force on the Bat,
So, the ball will apply a force of 1000N on the Bat
Therefore, Option C is correct

The objective lens and the eyepiece of a telescope are spaced 85 cm apart. If the eyepiece is123 D what is the total magnification of the telescope?
Answer:
The magnification would be "103.55". A further explanation is given below.
Explanation:
The given values are:
Distance between lens and eyepiece,
L = 85 cm
Eyepiece is,
= 123 D
Now,
The refractive power of eye piece will be:
⇒ [tex]\frac{1}{f_e}=123D[/tex]
[tex]f_e=\frac{1}{123D}[/tex]
[tex]f_e=0.813 \ cm[/tex]
The length of the telescope will be:
⇒ [tex]L=f_0+f_e[/tex]
⇒ [tex]f_0=L-f_e[/tex]
On substituting the values, we get
⇒ [tex]=85-0.813[/tex]
⇒ [tex]=84.187 \ cm[/tex]
Now,
The magnification of the telescope will be:
⇒ [tex]M=\frac{f_0}{f_e}[/tex]
⇒ [tex]=\frac{84.187}{0.813}[/tex]
⇒ [tex]=103.55[/tex]

a vector needs to be divided into components when ?
Answer:
Calculating the magnitude of a vector is only the beginning. The magnitude function opens the door to many possibilities, the first of which is normalization. Normalizing refers to the process of making something “standard” or, well, “normal.” In the case of vectors, let’s assume for the moment that a standard vector has a length of 1. To normalize a vector, therefore, is to take a vector of any length and, keeping it pointing in the same direction, change its length to 1, turning it into what is called a unit vector.To normalize a vector, simply divide each component by its magnitude. This is pretty intuitive. Say a vector is of length 5. Well, 5 divided by 5 is 1. So, looking at our right triangle, we then need to scale the hypotenuse down by dividing by 5. In that process the sides shrink, divided by 5 as well.

A stone is released from rest from a height of 60 m. How long does it take to hit the ground?
4.4 s
2.3 s
5.2 s
3.5 s
Answer:
3.5 s
Explanation:
Given
[tex]Initial\ Velocity (u) = 0m/s[/tex] --- because it starts from rest
[tex]Height\ (S) = 60\ m[/tex]
Required
Determine time (t) to hit the ground
This can be solved using the following motion equation
[tex]S = ut + \frac{1}{2}gt^2[/tex]
Substitute values for S and u and take g as 9.8m/s^2
[tex]60 = 0 * t + \frac{1}{2} * 9.8 * t^2[/tex]
[tex]60 = 0 + \frac{1}{2} * 9.8 * t^2[/tex]
[tex]60 = \frac{1}{2} * 9.8 * t^2[/tex]
Multiply through by 2
[tex]2 * 60 = 2 * \frac{1}{2} * 9.8 * t^2[/tex]
[tex]120 = 9.8 * t^2[/tex]
Solve for t^2
[tex]t^2 = \frac{120}{9.8}[/tex]
[tex]t^2 = 12.2448979592[/tex]
Take square roots
[tex]t = \sqrt{12.2448979592[/tex]
[tex]t = 3.49927106112[/tex]
[tex]t=3.5\ s[/tex] ---- approximated
It would take a stone released from a height of 60m, 3.5s to hit the ground.
EQUATION OF MOTION:
The time taken for a stone of height 60m to hit the ground can be calculated by using the following formula of motion:S = ut + ½at²Where;
S = distance (m)u = initial velocity (m/s)t = time a = acceleration due to gravity (9.8m/s²)Since the stone is released from rest, it would have a initial velocity of 0m/s. 60 = (0×t) + ½ × 9.8 × t²60 = 4.9t²t² = 60 ÷ 4.9t² = 12.24t = √12.24t = 3.5sTherefore, it would take a stone released from a height of 60m, 3.5s to hit the ground.Learn more at: https://brainly.com/question/13883874?referrer=searchResults
You are trying to tune the fifth string on your guitar, which is supposed to sound the A2 note (i.e., a note two octaves below A4). If the part of your guitar string in between where it is held down is 1.2 m and it has a mass of 0.006 kg, how much tension should you put the string under to get the right tuning?
Answer:
The value is [tex]T = 288 \ N[/tex]
Explanation:
From the question we are told that
The length of the guitar string considered is [tex]L = 1.2 \ m[/tex]
The mass is [tex]m = 0.006 \ kg[/tex]
Generally the tension is mathematically represented as
[tex]T = 4f ^2 m* L[/tex]
Here f is the frequency of the [tex]A_2[/tex] note which is [tex]f= 110 \ Hz[/tex]
So
[tex]T = 4* 110 ^2 * 0.006* 1.2[/tex]
=> [tex]T = 288 \ N[/tex]

why are magnetic materials attracted to magnets
Hello!
Topic: Magnetic material
Why are magnetic materials attracted to magnets?
Because when you expose any magnetic material to a magnetic field, magnetc material atoms start to align their electrons, because they flow by magnetic fields.
Then the atoms reacts to the field, and try to get together to the magnetic electrons field.
Thats why magnetic materials are attracted to magnets.
SONAR is an example of which type of wave behavior? Explain how it works and be sure to name the type of wave involved
Answer:
sound waves
Explanation:
SONAR (originally an acronym for Sound Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
In this method, to find the depth of an ocean, a strong ultrasonic wave is sent from the ship towards the bottom of the ocean. This ultrasonic wave is received back after it is reflected from the bottom of the sea. The time interval t for travel of sound waves from the source to the receiver after reflection is noted.The distance travelled by the ultrasound ray is given by the equation: 2d=vt, where v is the velocity of sound. From this the depth d can be calculated.
Answer:
Sonar uses sound waves to 'see' in the water.
Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.Sonar (sound navigation ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.[2] Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation,[3] and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.

5. An electric field has a strength of 10.0 N/C at a distance of 1.00 m from an unknown charge. At
what distance from the charge does the electric field strength equal 2.50 N/C?
Answer:
The electric field strength is equal to 2.50 newtons per coulomb at a distance of 2 meters.
Explanation:
From Classic Electrostatic Theory, we find that electric field ([tex]E[/tex]), measured in newtons per coulomb, is defined by the following equation:
[tex]E = \frac{F}{q_{O}}[/tex] (1)
Where:
[tex]F[/tex] - Electrostatic force, measured in newtons.
[tex]q_{O}[/tex] - Electric charge, measured in coulombs.
In addition and supposing that phenomena occurs between particles, electrostatic force is modelled after the Coulomb's Law:
[tex]F = \frac{k\cdot q\cdot q_{O}}{r^{2}}[/tex] (2)
Where:
[tex]k[/tex] - Electromagnetic constant, measured in newton-square meters per square coulomb.
[tex]q[/tex], [tex]q_{O}[/tex] - Electric charges, measured in coulomb.
[tex]r[/tex] - Distance between particles, measured in meters.
By applying (2) in (1), we get the following definition of electric field:
[tex]E = \frac{k\cdot q}{r^{2}}[/tex] (3)
Then, we observe that electric field is inversely proportional to the square of the distance. The following relationship is therefore constructed:
[tex]\frac{E_{2}}{E_{1}} = \left(\frac{r_{1}}{r_{2}} \right)^{2}[/tex] (4)
If we know that [tex]E_{1} = 10\,\frac{N}{C}[/tex], [tex]E_{2} = 2.50\,\frac{N}{C}[/tex] and [tex]r_{1} = 1\,m[/tex], then the distance is:
[tex]\left(\frac{E_{2}}{E_{1}} \right)\cdot r_{2}^{2}= r_{1}^{2}[/tex]
[tex]r_{2}^{2}=\left(\frac{E_{1}}{E_{2}} \right)\cdot r_{1}^{2}[/tex]
[tex]r_{2} = r_{1}\cdot \sqrt{\frac{E_{1}}{E_{2}} }[/tex]
[tex]r_{2} = (1\,m)\cdot \sqrt{\frac{10\,\frac{N}{C} }{2.50\,\frac{N}{C} } }[/tex]
[tex]r_{2} = 2\,m[/tex]
The electric field strength is equal to 2.50 newtons per coulomb at a distance of 2 meters.

the reactivity of aluminum compares
to the reactivity of other metals?
A more reactive metal will displace a less reactive metal from a compound. ... Because aluminum is more reactive than iron, it displaces iron from iron(III) oxide. The aluminum removes oxygen from the iron(III) oxide: iron is reduced.
A more reactive metal will displace a less reactive metal from a compound because aluminum is more reactive than iron, it displaces iron from iron(III) oxide.
What is compound?Compound has been combination of two or more than two different elements which are said to be chemically bond. So the compound has to be held by the chemical bond. A compound cannot be separate by the physical separation and after that the mixture you cannot be identified that it has compound or not.
Mixture has been combination of the two or more than different chemical elements which has not chemically bond. A mixture has been the physical combination of two or more elements in which the individual identities are remained and it also mixed by the solutions, suspension and colloids.
A compound cannot be separate by the physical separation and after that the mixture you cannot be identified that it has compound or not.Mixture has been combination of the two or more than different chemical elements which has not chemically bond.
