Answer:
B) the surface has a high coefficient of friction
When an object is not moving despite an applied force, it means that the frictional force is equal to or greater than the applied force. A high coefficient of friction indicates that the frictional force is strong, making it difficult to move the object. In this case, the frictional force is equal to the 100 N of force that Devon is applying, so the coefficient of friction for the surface must be high.
a wire carrying a 28.0 a current passes between the poles of a strong magnet such that the wire is perpendicular to the magnet's field, and there is a 2.35 n force on the 2.00 cm of wire in the field. what is the average field strength (in t) between the poles of the magnet?
The average field strength between the poles of the magnet is 5.56 T.
To find the average field strength between the poles of the magnet, we can use the formula for magnetic force:
F = BIL
Where F is the magnetic force, B is the magnetic field strength, I is the current, and L is the length of the wire in the field.
We know the force (2.35 N), current (28.0 A), and length of the wire in the field (2.00 cm), so we can rearrange the formula to find the magnetic field strength:
B = F / IL
B = 2.35 N / (28.0 A * 0.02 m)
B = 5.56 T
So the average field strength between the poles of the magnet is 5.56 T.

Free fall is any movement of a body where in gravity is the handiest force performing upon it. inside the context of popular relativity, where gravitation is reduced to a area-time curvature, a body in free fall has no pressure appearing on it.
An object inside the technical sense of the term "free fall" might not always be falling down within the ordinary sense of the term. An object transferring upwards won't commonly be taken into consideration to be falling, but if it's miles concern to best the force of gravity, it's far stated to be in free fall. The Moon is as a consequence in unfastened fall around the Earth, even though its orbital velocity keeps it in very some distance orbit from the Earth's surface.
In a kind of uniform gravitational discipline gravity acts on every a part of a frame about equally. when there are not any other forces, along with the normal pressure exerted among a frame (e.g. an astronaut in orbit) and its surrounding gadgets, it will result in the sensation of weightlessness, a situation that still occurs while the gravitational subject is susceptible (consisting of when far away from any source of gravity).

Consider a tall building located on Earths equator. As the earth rotates, a person on the top floor of the building moves faster than someone of the ground with respect to an inertial reference frame because the person on the ground is closer to the Earths axis. Consequently, if an object is dropped from the top floor to the ground a distance h below, it lands east of the point vertically below where it was dropped.
How far to the east will the object land? Express your answer in terms of h,g and the angular speed ω of the Earth. Ignore air resistance and assume the free-fall acceleration is constant over this range of heights.
what would we see if we were to view the universe from what we today consider the edge of the known universe?
The farther away we look, the farther back in time we’re able to see.
One thing we are certain about is that the Universe has an edge: not in space, but in time. Because the hot Big Bang occurred a known, finite time in the past — 13.8 billion years ago, with an uncertainty of less than 1% — there’s an “edge” to how far away we can see.
Even at the speed of light, the ultimate cosmic speed limit, there’s a fundamental limit to how far back we can see.
At distances of 31 billion light-years, corresponding to a time of just 550 million years after the Big Bang, we reach the edge.

4.67 x 10⁻¹⁹ J is the energy in joules if the wavelength of light detected is 431 nm.
The energy of a photon can be calculated using Planck's constant (h) and the frequency (v) of the light:
E = h * v,
where v is the frequency of the light and h is Planck's constant (h = 6.626 x 10⁻³⁴ J s).
The frequency of light can be calculated from its wavelength (λ) using the equation:
v = c / λ,
where c is the speed of light in a vacuum (c = 299,792,458 m/s).
So, for a wavelength of 431 nm (431 x 10⁻⁹ m), the frequency is:
v = c / λ = 299,792,458 m/s / (431 x 10⁻⁹ m) = 6.95 x 10¹⁴ Hz.
And finally, the energy of the photon can be calculated as:
E = h * v = 6.626 x 10⁻³⁴ J s * 6.95 x 10¹⁴ Hz = 4.67 x 10⁻¹⁹ J.

Which method would be the best way of producing a plant similar to the one you already have explain 
Answer:
whats your way (look at Explanation)
Explanation:
The best method for producing a plant similar to the one you already have will depend on the specific plant and the desired outcome. Here are some common methods of plant propagation:
Seeds: This is the most traditional and natural method of propagating plants. The seeds can be collected from the parent plant, or purchased from a reputable source, and then planted in soil or another growing medium.
Cuttings: Cuttings are pieces of stem or leaf taken from the parent plant and used to grow a new plant. This method is often used for plants that are difficult to propagate from seeds, or for plants that have special qualities (such as a particular color or texture) that the grower wants to preserve.
Layering: This is a method in which a stem is bent to the ground and rooted in soil, while still attached to the parent plant. The rooted stem can then be separated from the parent plant and grown as a new plant.
Grafting: Grafting involves taking a cutting from one plant (the scion) and joining it to the rootstock of another plant. This allows the grower to combine the desirable qualities of both plants into a single plant.
Tissue Culture: Tissue culture involves taking a small piece of tissue from the parent plant and growing it in a sterile, nutrient-rich environment. This method is often used for plants that are difficult to propagate through other means, and can also be used to produce a large number of identical plants.
The best method will depend on the specific requirements of the plant and the desired outcome. Some plants may respond better to one method over others, so it's important to do some research and choose the method that is best suited for your plant.

when this string vibrates at its fundamental frequency, it causes the air in a nearby stopped organ pipe to vibrate at that pipe's fundamental frequency. the speed of sound in the pipe is 344 m/s . what is the length of this pipe?
The speed of waves on this string of bass viol is 277.7m/s and the length of the second pipe is 1.04m.
Given the length of the bass viol is (L1) = 0.690m
The fundamental frequency of the bass viol is (f1) = 165Hz
Let the speed of waves on this string = v1
We know that frequency = speed/2 x length of pipe such that: f= v/2L
Then, v1 = f1 x 2 x L1 = 165 x 2 x 0.690 = 227.7m/s
Hence the speed of waves in string of bass viol is 227.7m/s
Given the speed of sound in second pipe (v2) = 344m/s
The frequency in second pipe = 165Hz
Let the length of second pipe = L2
The speed of sound in the pipe multiplied by the frequency of the string gives the length of the pipe:
f2 = v2/2L2

two twins make a round-trip journey from earth to a star that is 12 light-years distant. alice travels at a speed of 0.6c. bob departs 10 years after alice and travels at a speed of 0.8c. (a) show that the two twins arrive back on earth at the same time. (b) which twin is the younger when they return?
A)To show that the two twins arrive back on earth at the same time, we can use the time dilation formula: t' = t / sqrt(1 - v^2/c^2).
B) Alice is older than Bob when they return to Earth.
Let's use Earth as the observer at rest, and assume that the journey takes 24 years (12 years to the star and 12 years back). Then, Alice travels at a speed of 0.6c for the entire journey, so her time is dilated by a factor of:
t'_Alice = t / sqrt(1 - 0.6^2)
t'_Alice = 24 / sqrt(1 - 0.6^2)
t'_Alice = 40 years
Bob departs 10 years after Alice, so his journey takes 22 years (10 years to the star and 12 years back). He travels at a speed of 0.8c for the entire journey, so his time is dilated by a factor of:
t'_Bob = t / sqrt(1 - 0.8^2)
t'_Bob = 22 / sqrt(1 - 0.8^2)
t'_Bob = 40 years
Let's use Earth as the observer at rest again. For Alice, we have:
t_Alice = t'_Alice * sqrt(1 - 0.6^2)
t_Alice = 40 * sqrt(1 - 0.6^2)
t_Alice = 32 years
For Bob, we have:
t_Bob = t'_Bob * sqrt(1 - 0.8^2)

a parallel-plate capacitor, with plate area a and separation d, has a capacitance of c when the space between the plates is filled with air. then the space between the plates is half filled with a dielectric material with as shown below. what is the new capacitance?
The new capacitance of a parallel-plate capacitor filled partially with a dielectric material is given by C' = C * k, where C is the original capacitance and k is the relative permittivity of the dielectric material.
When a dielectric material is introduced between the plates of a parallel-plate capacitor, the capacitance increases. The relative permittivity represents how much the material can increase the electric field between the plates compared to air. For example, if k = 2, the capacitance doubles.
The new capacitance will depend on the specific dielectric material used and the value of k for that material. It is important to note that the plate area and separation distance remain constant in this scenario.

a block of 20 kg is pushed by a force of 40n for 4 m across a frictionless surface. the block was initially at rest before the force was applied. what is the work done by gravity?
A block weighing 20 kg is propelled along a frictionless surface for 4 meters by a force of 40n. Before the force of 5m/s2 was applied, the blocks was initially at rest.
Given a force as well as the distance it is applied over, how can you determine the jobs done on an object?Work = Force Distance is the formula for calculating work. The joule (J), sometimes known as the Newton meter (N m), is the Si derived unit for work. When an object is moved across a distance of one meter with 1 N of force, one joule is equal to the amount of labor that is accomplished.
Examples of the second law of motionAccording to Newton ’s 2nd Law of Motion, when a force applies on an object, it accelerates (gains speed).A nice example of such a law of motion in action is when you are riding your bicycle. Your bicycle makes up the bulk. The force is generated by your leg muscles as they press against the bicycle's pedals.

what is a noticeably different form or state of the same substance?
Phase is a noticeably different form or state of the same substance. Plasma is one of the four states of matter that can be found in everyday life in addition to solids, liquids, and gases.
What is a material's state?These four states of matter—solids, liquids, gases, and plasma—can all be encountered in daily life. Nevertheless, a variety of other states of matter have been discovered. When a substance switches between two states of matter without actually displaying the traits of either state, some of these new states are generated.
Matter can shift states when energy is introduced into or removed from a system. Usually, temperature or pressure fluctuations are the sources of this energy. When matter changes states, phase transitions or phase alterations take place. A phase is a material's visibly changed form or state.
What do you mean when you say that a material has changed states?Solid from to. Gas to Liquid A substance changing from one physical form to another is known as a change of state. Physical changes are the basis of all state changes. Depending on the state of the substance, the particles have varying energies.
