What does the research show are the most favorable conditions for attitude change?
In terms of attitude change, the fundamental tenet of the cognitive theory would be that individuals are typically driven to lessen dissonance, which could be accomplished by altering their attitudes but also beliefs.
What is cognitive theory ?Cognitive theories concentrate on the premise that how exactly what people think causes the arousal of emotions, suggesting that some thoughts, as well as beliefs, as well as beliefs, contribute to healthy emotions as well as adaptive behavior while others lead to disturbing emotions and behaviors.
What is attitude change?When people sense unease or guilt as a result of cognitive dissonance, they can actively lessen the dissonance by altering their attitude, beliefs, and even conduct in relation to it in order to attain consistency with both the contradictory cognitions.

Object X and object Y, of charge +Q and −2Q, respectively, are separated by a distance r0, as shown in the figure.
(a) Determine an equation for the magnitude and direction of the electric force that is exerted on object Y from object X in terms of Q, r0, and physical constants, as appropriate.
(b) The charge of object X is changed so that it has a charge of −4Q, and the separation distance between the two objects is changed to 2r0. In a clear, coherent paragraph-length response that may also contain figures and/or equations, predict how the electric force exerted on object Y from object X changes from part (a), and predict how the net charge of the two object system changes from part (a).
Answer:
(a) The magnitude of the force electric force F = k ×(+Q) × (-2·Q)/r₀² = -2·Q²/(r₀²) which can be written as follows;
[tex]F = \dfrac{k \times (+ Q) \times (-2\cdot Q)}{r_0^2} = -\dfrac{k \times 2 \times Q^2}{r_0^2}[/tex]
Given that the charge of Y is twice the charge on X, we have the charge X will move towards the charge Y which is the +x direction
(b) The force, F, acting between the charges is given as follows;
[tex]F = \dfrac{k \times Q_1 \times Q_2}{r_0^2}[/tex]
When, Q₁ = X = -4Q, Q₂ = Y = -2Q, and r₀ = 2·r₀ we have;
[tex]F = \dfrac{k \times (-4\cdot Q) \times (-2\cdot Q)}{(2 \cdot r_0)^2} = \dfrac{k \times 8 \times Q^2}{4 \cdot r_0^2} = \dfrac{k \times 2 \times Q^2}{r_0^2}[/tex]
Therefore, the electric force exerted on object Y by the object X is the same and acts in an opposite direction to the force of X on Y in (a)
The net charge of the two objects in part (a) is Q - 2Q = -Q
The net charge of the two objects in part (b) is -4Q - 2Q = -6Q
Therefore, the net charge increases by a factor of 6 in part (b)

Which Period 3 element would you expect to have the highest electrical and
thermal conductivity?
A. Chlorine (CI)
B. Phosphorus (P)
C. Sulfur (S)
D. Sodium (Na)
Answer:
The correct option is D
Explanation:
Generally, thermal and electrical conductivity is affected by valence electrons in an atom. These valence electrons carry electric charges (or conduct heat as the case may be) throughout the atom. The fewer the valence electrons, the higher its conductivity - this is as a result of free movement within the atom. The higher the valence electrons, the lesser its conductivity and when the outermost electrons have completely filled the outermost shell, the atom would be an insulator as there won't be carriers of electric charges.
Hence, from the above, sodium would be expected to have the highest electrical and thermal conductivity because it has just one electron in it's outermost shell
Answer:D

Grain is pouring into a silo to be stored for later use. Due to the friction between pieces of grain as they rub against each other during the pouring process, one piece of grain picks up a charge of 6.0 E -10 C and another piece of grain picks up a charge of 2.3 E -15 C. What is the electric force between them if the pieces of grain are 2 cm apart?
Answer:
F = 3.105 10⁻²⁰ N
Explanation:
For this exercise let's use Coulomb's law
F = k q₁ q₂ / r²
in this case each of the grains has a charge
q1 = 6.0 10⁻¹⁰ C
q2 = 2.3 10⁻¹⁵ C
and they are separated by a distance r = 2 cm = 0.02 m
let's substitute
F = 9 10⁹ 6.0 10⁻¹⁰ 2.3 10⁻¹⁵ / 0.02²
F = 3.105 10⁻²⁰ N
An object travels 15m in 3 s. What is it's speed?
Answer:
5 m/secExplanation:
speed = distance / time
= 15m / 3sec
= 5 m/sec
Answer:
5 m/s
Explanation:
The equation for speed is distance/time. The distance, 15, will go over the time, 3. So, we have 15/3.
You can simplify this by dividing both sides by 3. 15/3 is 5. 3/3 is 1. Now we have 5/1, with 5 as meters, 1 and second.
Therefore, the correct answer is 5 m/s.

An autographed baseball rolls off of a 0.93 m high desk and strikes the floor 0.56 m away from the desk. How fast was it rolling on the desk before it fell? The acceleration of gravity is 9.81 m/s^2. Answer in units of m/s.
First of all, how long does it take it to fall 0.93m to the floor ?
Distance falling from rest = (1/2) · (g) · (T²) <== memorize this formula
(0.93 m) = (1/2) (9.8m/s²) (T²)
Divide each side by (4.9 m/s²) : T² = (0.93/4.9) = 0.1898 s²
Square root each side: T to hit the floor = 0.436 second
It got 0.56m away from the desk horizontally in 0.436 sec.
Speed = (distance) / (time) <=== memorize this formula
Speed = (0.56 m) / (0.436 sec)
Speed = 1.28 m/s

How can mathematical models of Newton's law be used to test and improve engineering design ? Claim, Evidence, Reasoning PLEASE ! I need this badly !
Answer:
the mathematical models, Newton's second law, improve the response of our designs and allow us to modify them to be more resistant.
Explanation:
When an object is designed it is done based on some models or guides, specifically Newton's second law is given in the form
∑ F = m a
We can make a design and test with forces applied in several different places and with different intensity, to find weak points in the design, this is done a lot today in the construction of tall buildings, in the design of airplanes; The great advantage of this is that it allows you to see problems without significant cost of money and human lives.
There are also designs that can be modified to improve the response of our system to different external stimuli, this is widely used in the design of bridges, to see the response of the structure before load changes and different climatic conditions.
In summary, the mathematical models, Newton's second law, improve the response of our designs and allow us to modify them to be more resistant.

A 438 gram ball is traveling east at 39 m/s when it is hit by a 2.4 kg softball bat. After being in contact with the bat for 302 ms, the ball rebounds at a speed of 28 m/s.
Determine the impulse vector (magnitude and direction) in kg*m's felt by the bat. Treat east as the positive direction.
Answer:
The magnitude of the impulse vector of the bat is 29.346 kg.m/s
The direction of the impulse vector of the bat is in the initial direction of the ball before impact
Explanation:
The given parameters are;
The mass of the ball, m₁ = 438 g
The speed of the ball = 39 m/s
The mass of the softball bat = 2.4 kg
The time of contact = 302 ms = 0.302 seconds
The speed of rebound = 28 m/s
The impulse = The change in momentum = Δp = F × Δt = m × Δv
The impulse on the ball = m₁ × Δv = 0.438 × (39 - (-28)) = 29.346 kg·m/s
Given that force of reaction of the bat is in opposite direction but equal to the force of the ball, and the time and the duration of contact with the ball is the same for both the ball and the bat, the impulse vector ore equal and opposite
Therefore, the magnitude of the impulse vector of the bat = 29.346 kg.m/s
The direction of the impulse vector of the bat = The initial direction of the ball before impact.

why the blood pressure in human body is greater at the feet than at the brain. please help!!!!
Answer:
The pressure of liquid column is given by p=hpg, where h is depth, p is density and g is acceleration due to gravity.
Therefore, pressure of the liquid column increases with depth. The height of the blood column in a human body is more at feet than at the brain. Therefore, the blood pressure in humans is greater at the feet than the brain.

A.
the ocean
B.
the Sun
C.
the solar system
D.
the Earth
Answer:
The earth
Explanation:
Answer:
D. the Earth
Explanation:
The Earth has a solid metal core at the center, which is similar to the pit of a peach. The Earth also has many thick layers of rock and liquid metal between the surface and the center of the Earth, similar to how a peach has a layer of skin and a thick section of fruit. The other answer choices don't have any similarities to a peach. The ocean is entirely liquid, the sun is a ball of gas, and the solar system contains lots of different planets and stars that all are made up of very different things.
