A) helping businesses pay their workers less B) giving Congress the power to create courts C) granting government the power to seize people's property D) securing the rights of the wealthy over the rights of the poor

Answers

The correct answer is B) Giving Congress the power to create courts

Explanation:

One of the principles the Constitution mentions in the preamble is Justice, this is mentioned in "We the people of the United States, in order to form a more perfect union, establish justice..." According to this, a priority is to make the country have justice, which is possible through courts, laws, among others. In this context, the action that would be allowed is "Giving Congress the power to create courts" because this might ensure the justice principle is applied in the U.S.

The point at which Mary's sneezing stopped is an example of _____.

Answers

Answer: Extinction

Explanation: Extinction simply means cessation. A condition whereby an action or behavior exhibited by an individual or organism eventually stops. In psychological parlance, extinction is usually attributed to the discontinuance of a certain behavior usually due to non - reinforcement or eventual absence of the conditioned stimulus.

In the scenario above, the point at which Mary stopped sneezing is called extinction which is due to the removal of the cat which is the cause of Mary's sneezing behavior.

A camera lens focuses on an object 75.0 cm from the lensThe image forms 3.50 cm behind the lens. What is the magnification of the image?

Answers

Answer:

7/150

Explanation:

The following data were obtained from the question:

Object distance (u) = 75cm

Image distance (v) = 3.5cm

Magnification (M) =..?

Magnification is simply defined as:

Magnification (M) = Image distance (v)/ object distance (u)

M = v /u

With the above formula, we can obtain the magnification of the image as follow:

M = v/u

M = 3.5/75

M = 7/150

Therefore, the magnification of the image is 7/150.

In which of the following situations or places would you want to reduce the
force of friction?
I A. Skiing down a hill during a race.
B. Walking down a steep hill.
C. Sitting in the bed of a pickup truck while it turns a corner
D. In the axle of the wheels while you ride your bicycle.

Answers

Answer:

D

Explanation:

The correct answer would be in the axle of the wheels while you ride your bicycle.

Options A, B, and C requires that the forces of friction is increased in order to have more control.

However, option D requires that there is a minimal frictional force in the axle of the wheels of a bicycle while riding so that a little effort would be required to keep the bicycle moving.

The lesser the friction, the lower the effort that would be needed to keep the bicycle moving and vice versa.

Why does the pattern of colors repeat in a thin soap film? Please use 2 content related sentences. (ref: p.522-530)

Answers

Answer: The pattern of colors that repeat in a thin soap film is a result of the interference of light waves reflecting off the front and back surfaces of the film. The specific colors seen are determined by the thickness of the film, with different wavelengths of light being reflected or refracted at different angles, creating the characteristic rainbow pattern.

An overhead projector lens is 32.0 cm from a slide (the object) and has a focal length of 30.1 cm. What is the magnification of the image? (Unit=cm) PLS HELP

Answers

Answer: M = 14.3

Explanation:

Given the following :

Object distance (u) = 32cm

Focal length (f) = 30.1 cm

Magnification = image distance (v) / object distance (u)

Recall ; 1/f = 1/u + 1/v

1/30.1 = 1/32 + 1/v

1/v = 1/30.1 - 1/32

1/v = (32 - 30.1) / 963.2

1/v = 2.1 / 963.2

1/v = 0.0021802

v = 1/0.0021802

v = 458.66666 cm

Therefore, Magnification 'M' = v / u

M = 458.66666 / 32

M = 14.333333

M = 14.3

Answer:

M = -15.8

Explanation:

object distance = 32cm

focal length = 30.1 cm

To find M we first need to find di or image distance

I will use the equation: 1/f = 1/di + 1/do

By changing the equation to 1/f - 1/di = 1/do we get 0.0019725

equation with numbers plugged in:

1/30.1 - (1/32) = 0.0019725

To change 1/do to do we divide 1 by 0.0019725

You should get 506.97

Now use the equation

M = -(di/do)

M = -(506.97/32)

You should get M = -15.8

ОА.
3,600 ohms
О В.
16 ohms

D. 0.063 ohms

Answers

Answer:

16 ohms

Explanation:

V= I ⋅ R

where,  V  is the net potential difference in the circuit,  I  is the current in the circuit and  R  is the net resistance of the circuit.  

In this case,  V = 240  volts,  I = 15  amperes.

240 = 15 ⋅ R  

⇒ R = 240/ 15 = 16  ohms

Given the resistivities below, which material is best described as an insulator?
A. 4.5 22•m
B. 2.8 x 10-8
12.m
C. 1.7 x 10-8 2•m
D. 3.2 x 108 2.m

Answers

Answer: D) 3.2 × 10^8

Explanation: Insulators are best described as materials which are poor conductors of electricity and hence do not allow passage of electricity through them. Resistivity are hence used to describe property or characteristic of a material which does not allow the flow or passage of electric current.

In summary, materials which high resistivity values are referred to as Insulators. Conversely, those with low resistivity or high conductivity values are called conductors while those with intermediate values are named semiconductors.

In the question given above, the material with a resistivity value of 3.2 × 10^8 - - - has a very high resistivity value (320000000Ω), the other options given have very low resistivity values ; 0.0000000017, etc and are most likely to be conductors due to their excessively low resistivity values.

The general kinematic equations of motion for vertical displacement can also be simplified significantly. Write the simplified
equation for y in this case. Explain how you have been able to simplify it from this general displacement equation:

Answers

Answer:

Δy = v₀t + (1/2)gt²

where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards

Explanation:

The general kinematic equation for horizontal displacement is gives as:

Δx = v₀t + (1/2)at²

Where

Δx = change in the x direction

v₀ = initial velocity

t = time

a = acceleration

If the body is vertically instead of horizontally, Δx is changed to Δy

Δy = v₀t + (1/2)at²

For a vertical moving body, the acceleration it experiences is the gravitational accerelation of the earth 'g'

So the equation becomes:

Δy = v₀t + (1/2)gt²

where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards

The general kinematic equations of motion for vertical displacement is written as [tex]h = v_0_yt - \frac{1}{2} gt^2[/tex].

The general kinematic equations of motion for vertical displacement is written as follows;

[tex]h = v_0_yt - \frac{1}{2} gt^2[/tex]

where;

h is the vertical displacement of the object[tex]v_0_y[/tex] is the initial vertical velocity of the objectg is the acceleration due to gravityt is the time of motion of the object

Thus, the general kinematic equations of motion for vertical displacement is written as [tex]h = v_0_yt - \frac{1}{2} gt^2[/tex].

a toy airplane is flying at a speed of 8 m/s with an acceleration of 0.9 m/s^2. How fast is it flying after 2 seconds? A)9.8 m/s B)8.1 m/s C)5.2 m/s D)3.6 m/s

Answers

Answer:

A) 9.8m/s this answer is correct.

The acceleration is increasing by 0.9m/s^2 .

so, in each second it will increase by 0.9m/s^2.

Therefore, in 2 second

0.9 * 2

= 1.8m/s

Now,

8 + 1.8

= 9.8m/s

Answer is A cause we know v=u+at so v=8+0.9 into 2 this is equal to 8+1.8=9.8m/s

The graph below shows the conservation of energy for a skydiver jumping out
of a plane and landing safely on the ground. Which energy is represented by
line B?


A. Elastic energy
B. Kinetic energy
C. Light energy
D. Potential energy

Answers

Answer:

The correct option is:

B) Kinetic Energy

Explanation:

We know that if a body is placed at a certain height, it possesses Potential Energy, which is represented by 'mgh'. In this case, when the skydiver is present in the plane, before jumping, he has potential energy as he is at height 'h'.

As Kinetic energy is given as '(1/2)mv²' dependent on velocity of the object, when the skydiver jumps of the plane, his height starts decreasing, which decreases his Potential Energy. As energy can neither be created or destroyed, but is converted to one form or another, all this Potential energy starts to convert into Kinetic energy. As Potential Energy decreases with distance, Kinetic energy increases. Hence, line B represents Kinetic Energy.
