an object is placed in front of a curved mirror as shown. which of the labeled positions is the current position of the image

Answer:

C. It has been moved from another location.

Explanation:

Residual soil is that which has been formed by the weathering of the rocks in the same place where it is located, with a virtually zero displacement of the particles, while the transported soil is that which forms a loose mantle, resulting from the disintegration or decomposition of the rocks. Since it is an unconsolidated mantle, its products are transported by water, wind or ice.

Answer:Hello the correct answer for penn foster is it forms on uncosolidated materials.

Explanation:

Answer:

8.57 m

Explanation:

To solve the problem, we have to decompose the two vectors along the two directions first:

Vector A:

- x component: Ax = +9.66 m

- y compoment: Ay = 0 (the vector lies along the x-axis)

Vector B:

- x component: [tex]B_x = -(12.0 m) cos 45^{\circ}=-8.49 m[/tex]

- y component: [tex]B_y = (12.0 m) sin 45^{\circ}=8.49 m[/tex]

So now we can find the sum of the two vectors by adding the components along each axis:

[tex]R_x = A_x + B_x = 9.66 m - 8.49 m = 1.17 m[/tex]

[tex]R_y = A_y + B_y = 0 + 8.49 m = 8.49 m[/tex]

And the magnitude of the sum is given by Pythagorean theorem:

[tex]R=\sqrt{R_x^2+R_y^2}=\sqrt{(1.17 m)^2+(8.49 m)^2}=8.57 m[/tex]

To find the magnitude of the sum of two vectors, you add their magnitudes if they're in the same direction. Given the vectors are 12.0 m at 45.0° and 9.66 m (undirected), assuming the same direction, the magnitude of the sum is 21.66 m.

In this problem, we're dealing with vector addition in Physics, specifically calculating the magnitude of the sum of two given vectors. Given that the first vector has a magnitude of 12.0 m at an angle of 45.0°, and the second vector has a magnitude of 9.66 m (with no specific direction provided), we can use the principle of vector addition to find the resultant vector.

In the absence of the direction of the second vector, let's presume it's following the same direction for simplicity. The sum of these vectors (or the resultant vector) can be obtained by adding the magnitudes of the two vectors since they are in the same direction. So, the magnitude of the resultant vector is 12.0 m + 9.66 m = 21.66 m.

If the second vector was in a different direction, we would have to decompose the vectors into their horizontal and vertical components, add these components separately, and then calculate the magnitude and direction of the resultant vector using trigonometric principles.

Answer:

"Wave 3 resulted from constructive interference and Wave 4 resulted from destructive interference."

Explanation:

Constructive Interference:

When two waves meet in such a way that their crests line up together, then it's called constructive interference. The resulting wave has a higher amplitude.

Destructive Interference:

In destructive interference, the crest of one wave meets the trough of another, and the result is a lower total amplitude.

The amplitude of Wave 3 is higher than both the Waves, 1 & 2, so it must be a result of constructive interference.

The amplitude of Wave 4 is less than both the Waves, 1 & 2, so it must be a result of destructive interference.

Answer:

Answer:

the earth would be a different place, for example there wouldnt be anymore volcanic eruptions

Explanation:

when the earth plates stops moving is the source to everything, the ground would shake, waves would stop ect

There would be no new island formations when oceanic plates stop moving.

Explanation:

The oceanic plate or the tectonic plate movement determines the several activity of land and ocean which keep making the life possible. As the plate movement stop, volcanic eruption will be stopped, sea floor will not spread further, every activity below ground will cease.

The pressure increases inside the core and so does the erosion. The continent will be lost with all its life on the land. Oceanic life will survive more but may freeze the planet to die.  

The most common types of precipitation are:

- rain

- snow

- hale

The rain comes in liquid form. In order for the rain to occur, the temperature in the upper parts of the troposphere should not be too low, thus the condensation of the water vapor can only go from gaseous to liquid form. The rain occurs in the lower latitudes, as well as in the mid-latitudes mostly from spring to autumn.

The snow occurs in the higher latitudes and in the mid-latitudes during winter. In order for the snow to form, the temperatures in the upper parts of the troposphere should be below the freezing point, so the water vapor crystallizes into small ice crystals.

The hale occurs in the warmer period in the mid-latitudes, and occasionally in the lower latitudes. The hale is formed when during the condensation of the water vapor into liquid form, the air mass encounters much lower temperatures below the freezing point. This results in the formation of large crystals that fall on the surface in the form of frozen, circular-shaped pieces.

Answer:

Therefore, gravity does 588.6 Joules of work in causing the 6 kg hammer to fall 10 meters.

Explanation:

Gravity does work by exerting a force on the hammer over a certain distance. We can calculate this work using the formula:

Work = Force x Distance (where force is parallel to the direction of movement)

In this scenario:

Force = Gravitational force acting on the hammer (Weight of the hammer)

Distance = Height fallen

Force:

We can calculate the gravitational force (weight) using the formula: Weight = Mass x Gravity

Mass of the hammer (m) = 6 kg

Gravity (acceleration due to gravity) = 9.81 m/s² (approximately)

Weight = 6 kg * 9.81 m/s² = 58.86 N (Newtons)

Distance:

Distance (d) = 10 m

Work done by gravity:

Work = Force x Distance = 58.86 N * 10 m = 588.6 Joules

Therefore, gravity does 588.6 Joules of work in causing the 6 kg hammer to fall 10 meters.

Answer: A. Object A will have a positive charge.

Explanation: If the number of protons and electrons are the same, their net charges cancel each other out, and you have a neutral charge. If electrons are transferred to another object, the amount of positive charge will outweigh the amount of negative charge. As a result, you are left with an overall positive charge in object A. Meanwhile, object B is now negative.

Final answer:

When electrons are transferred from object A to object B, object A will become positively charged (option A) due to the loss of negatively charged electrons. This makes the answer A. Object A will have a positive charge.

Explanation:

If some electrons are transferred from object A to object B, the correct answer is A. Object A will have a positive charge. This is because electrons have a negative charge, and removing them from an object leaves that object with an excess of positive charge in the form of protons (which are positively charged and present in every atom). Object B, receiving the electrons, will become negatively charged since it gains additional negative charges.

Answer:

Maximum compression of the spring: [tex]\rm 0.423\; m[/tex].

Explanation:

Let [tex]x[/tex] be the maximum compression, in meters, of the spring.

What's the initial kinetic energy of this block?

What's the final kinetic energy of this block?

Let the initial height of the block be zero.

The height of the block will be [tex]\rm -1.8\;m[/tex] by the time it reaches the top of the spring. However, the height of the block will become even more negative as the spring compresses. If the maximum compression of the spring is [tex]x[/tex] meters, the height of the block will be [tex]-(1.8 + x)[/tex] meters by the time the spring reaches its maximum compression.

The change in the height of the block will thus be [tex]-(1.8 + x)\;\mathrm{m}[/tex] relative to the initial position of the block. The change in the block's potential energy due to gravity will be:

[tex]\Delta \mathrm{GPE} = m\cdot g\cdot \Delta h = 6\times 9.8 \times (-(1.8 + x)) = -105.948- 58.86\;x[/tex].

The mechanical energy of an object is the sum of its kinetic energy and its potential energy. What will be the change in the mechanical energy of the block?

[tex]\text{Change in Mechanical Energy} \\ = \text{Change in KE} + \text{Change in PE} \\ = (0 - 48) + ((-105.948- 58.86\;x) - 0)\\ = (-153.948 - 58.86\;x)\; \text{J}[/tex].

The block has lost [tex](153.948 + 58.86\;x)\; \text{J}[/tex] of energy as it travels from its initial position to the place where the spring is most compressed. Energy conserves. Those energies are transferred to the spring. Assume that there's no energy loss in this process. All those [tex](153.948+ 58.86\;x)\; \text{J}[/tex] would have become the elastic potential energy of the spring.

On the other hand, it is assumed that the spring is compressed by a distance of [tex]x[/tex] meters. By Hooke's Law, the elastic potential energy of the spring will be:

[tex]\displaystyle \text{Elastic Potential Energy} = \frac{1}{2} \; k\cdot x^{2} = \frac{1}{2}\times 2000 \times x^{2} = 1000\; x^{2}\;\text{J}[/tex].

There are thus two expressions for the Elastic Potential Energy of the spring:

The two expression shall be equivalent. Equate the two expressions and solve for the compression of the spring, [tex]x[/tex].

[tex]153.948+ 58.86\;x = 1000\; x^{2}[/tex].

[tex]1000\; x^{2}- 58.86\;x - 153.948 = 0[/tex].

[tex]\displaystyle x_{1} = \frac{-(-58.86) +\sqrt{(-58.86)^{2} - 4\times 1000 \times (-153.948)}}{2\times 1000} = \rm 0.423[/tex].

[tex]\displaystyle x_{2} = \frac{-(-58.86) +\sqrt{(-58.86)^{2} - 4\times 1000 \times (-153.948)}}{2\times 1000} = -0.364[/tex].

Consider the expression for the height of the block when it is at the top of the spring and when the spring reaches maximum compression:

The maximum compression of the spring will be 0.423 meters.

Answer:10842.33m/s

Answer: Aluminum, because the parts that make a refrigerator are most definitely aluminum

Explanation:

A typical refrigerator door is made of steel or aluminum and not by iron. Similarly, the exterior cabinet also made of aluminum metal.

The outer cabinet and door, the inner cabinet or liner, the insulation placed between the two, the cooling system, the refrigerant, and the fittings make up the majority of modern refrigerators. Aluminum or steel sheet metal that has occasionally been preprinted is used to make the cabinet and door.

Typically, the metal is bought in a coil and supplied either straight into the production process or chopped to size and fed in sheets. Like the outside cabinet, the inside cabinet is built of sheet metal or plastic.

Fiberglass or polyfoam insulation is used to fill the space between the inner and exterior cabinets. Aluminum, copper, or an alloy is used to make the compressor, condenser, coils, and fins of the cooling system.

Explanation: because there is always a force that causes motion..

Also I’m back

Where’s the old gang?

Newton's first law of motion states that an object in motion will continue to move at a constant speed in a straight line unless acted upon by an external force. So, not all objects in motion require a force to keep them in motion.

According to Newton's first law of motion, an object in motion will continue to move at a constant speed in a straight line unless acted upon by an external force. So, it is not true that any object in motion must experience a force to keep it in motion. The force is only necessary to change the object's state of motion, such as slowing it down or altering its direction.

For example, imagine a hockey puck sliding on a frictionless ice rink. Once given an initial push, the puck will continue moving at a constant speed in a straight line until it encounters an external force, such as contact with the boards or another player.

Therefore, I disagree with the student's claim. An object in motion does not necessarily need a force to keep it in motion, but rather a force is required to change its state of motion.

Explanation:

Trust me bro.

B. During reflection, rays stay in the original medium, and during refraction, rays pass into a new medium describes how rays behave when they travel through media during reflection and refraction.

Rays change direction as they reflect off the surface, move from one transparent medium to another, or pass through a medium whose composition is constantly changing.

Reflection involves changing the direction of the wave as it bounces off the barrier. Refraction of a wave involves changing the direction of the wave as it transitions from one medium to another. The refraction or curvature of a wave path involves changes in wave velocity and wavelength.

Explanation:

The momentum of an object is defined as

p = mv

where

m is the mass

v is the velocity

In this problem we have,

v = 15 m/s is the velocity of the stone

p = 7.5 kg m/s is the momentum

Solving for m, we can find the mass of the stone:

[tex]m=\frac{p}{v}=\frac{7.5 kg m/s}{15 m/s}=0.5 kg[/tex]

Data:

p = 7.5kg-m/s

v = 15m/s

m = ?

Explanation:

P = m×v

m = P/v

m = 7.5/15

m = 0.5kgs

Acceleration due to gravity is about 9.8 m/s²

So after every second, the speed increase by 9.8 m/s

After 1 second, the object would fall at a speed of 9.8 m/s

After 2 seconds the object would fall at a speed of 19.6 m/s

So after 4 seconds, the object is going to be at a speed of:

9.8 x 4 = 39.2 m/s

Photosynthesis

Light energy from the sun  stimulates photosynthesis by green plants. One major component of the carbon cycle is the reduction of the carbon (IV) oxide content in the atmosphere by plants. Plants take in Carbon (IV) oxide to use during the process of making their own food. During this process light energy is absorbed by chlorophyll and is used to convert carbon (IV) oxide and water to glucose.

This glucose is used during respiration by living organisms that give out carbon (IV) oxide. The cycle continues.
