why can many ecosystems exit in one biome?
Answer:
Plants and animals that live in a biome must be able to live and reproduce in the conditions
Explanation:
Resulting from past and current geoscience processes, Earth's mineral, energy, and groundwater resources are unevenly distributed. As humans continue to remove these limited and often non-renewable resources, their distributions significantly change. This map shows some of the world's major tectonic plate boundaries. Volcanic and hydrothermal activity occur as a result of the energy released along these boundaries, creating an ideal environment for the concentration of minerals. Which statement provides another rationale for higher mineral concentrations near plate boundaries compared other parts of the world? A) The speed of mineral formation is increased by the high levels of groundwater found at plate boundaries. B) Sediment from erosion usually deposits near plate boundaries, and volcanic activity causes it to form minerals. C) Rocks with high mineral concentrations buried deep in the mantle can be pushed near the surface as plates move. D) The magnetic pull of Earth's mantle is strongest at plate boundaries, pulling minerals in Earth's crust toward them.
Answer:
C
Explanation:
Rocks with high mineral concentrations buried deep in the mantle can be pushed near the surface as plates move
Statement provide another rationale for higher mineral concentrations near plate boundaries is rocks with high mineral concentrations buried deep in the mantle can be pushed near the surface as plates move.
What is mineral?A mineral is an inorganic element or compound that occurs in nature and has a recognizable chemical composition, crystal structure, and physical characteristics. Quartz, feldspar, mica, amphibole, olivine, and calcite are examples of common minerals.
A body of undifferentiated mineral materials or an amalgamation of one or more minerals is referred to as a rock. Granite, basalt, limestone, and sandstone are typical rocks.
The higher mineral concentrations near plate boundaries is rocks with high mineral concentrations buried deep in the mantle can be pushed near the surface as plates move.

a horizontal string is stretched between two points a Distance 0.80 metre apart the tension in the string is 90 Newtonand it is mass is 4.5 g calculate the wavelength and frequency of the three lowest frequency modes of vibration of the string
Answer:
a) v = 126.5 m / s, b) λ₁ = 1.6 m, λ₂ = 0.8 m, λ₃ = 0.533 m, f1 = 79 Hz,
λ₂ = 0.8 m, f₃ = 237 Hz
Explanation:
This is an exercise we are going to solve in parts, let's start by looking for the speed of the wave in the string.
v = [tex]\sqrt { \frac{T}{ \mu } }[/tex]
the rope tension is T = 90 N and the density can be calculated
μ = m / l
let's calculate
μ = 4.5 10⁻³ / 0.80
μ = 5.625 10⁻³ kg/m
let's calculate the speed
v = [tex]\sqrt{ \frac{90 }{5.625 \ 10^{-3}} }[/tex]
v = 126.5 m / s
For the second part there is a process of resonance in the string. The points where it is attached are nodes so, if L is the length of the chord
L = ½ λ 1st harmonic
L = 2/2 λ 2nd harmonic
L = 3/2 λ 3rd harmonic
L = n/2 λ n harmonic
the wavelength of the first three harmonics is requested
let's calculate
λ₁ = 2L
λ₁ = 2 0.8
λ₁ = 1.6 m
λ₂ = L
λ₂ = 0.8 m
λ₃ = ⅔ L
λ₃ = ⅔ 0.8
λ₃ = 0.533 m
To calculate the frequency we use that the speed is related to the wavelength and the frequency
v = lam f
f = v / lam
we calculate
f1 = 126.5 / 1.6
f1 = 79 Hz
f2 = 126.5 / 0.8
f2 = 158 Hz
f3 = 126.5 / 0.533
f3 = 237 Hz

Galaxies are made of millions of stars, interstellar gas, and dust that stay relatively close together due to magnetic attraction.
True or False?
if its false please explain why
Answer:
True
Explanation:
Its true
The statement "Galaxies are made of millions of stars, interstellar gas, and dust that stay relatively close together due to magnetic attraction." is false.
What is Gravitation?Gravitation, also known as gravity, is a fundamental force of nature that attracts objects with mass or energy toward each other. It is the force that keeps planets in orbit around stars, stars in orbit around the centers of their galaxies, and all objects on the surface of the Earth.
According to Newton's law of gravitation, every mass in the universe attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the larger the masses of the objects and the closer they are to each other, the greater the gravitational force between them.
In this question,
Galaxies are made up of millions, or even billions, of stars along with interstellar gas and dust. However, the gravitational force, not magnetic attraction, is what holds the stars and other components of a galaxy together. The gravitational attraction between the stars and other matter in the galaxy is what allows them to orbit around the center of mass of the galaxy. In fact, the vast majority of matter in a galaxy is dark matter, which is an invisible and unknown form of matter that interacts gravitationally with other matter in the galaxy.
While magnetic fields do exist in galaxies, they are generally much weaker than gravitational forces and play a secondary role in the structure and dynamics of galaxies.

A current of 27 flows through a filament lamp when potential difference of Vis applied across How many electrons will move through the lamp in a time of 1 hour?
Answer:
6.075×10²³ Electrons
Explanation:
From the question,
Q = it............................. Equation 1
Where Q = quantity of charge, i = current, t = time.
Given: i = 27 A, t = 1 hours = 1×60×60 = 3600 seconds.
Substitute these values into equation 1
Q = 27×3600
Q = 97200 C.
If, one electron = 1.6×10⁻¹⁹ C,
Therefore, n electron = 97200×1/1.6×10⁻¹⁹ C.
n = 6.075×10²³ Electrons
charge is moving in a magnetic field that points to the left. What direction can the charge move and experience no magnetic force? Check all that apply
Answer:
The answer is "left"
Explanation:
The electric charge was its material property when it has fewer ions in its atoms than protons. There would be a negative charge of electrons as well as a positive electrode for such protons. Although Material contains more electrons than protons, if Material contains fewer electrons than protons, it is positively charged. An electrical charge is a loading motion, so it forms a current if the loads will move from an insulator, that's why the above given choice is correct.

what is the difference between atoms and particals? Help
An atom is the smallest unit of matter that forms a chemical element. An atom is made up of three kinds of subatomic particles: electrons, protons, and neutrons.A molecule is a combination of atoms bonded together through a covalent bond. Generally, we think of molecules as having no charge (although molecular ions do exist)
Calculate the period of oscillation of a pendulum with a small amplitude whose length is 2.5 meters
Answer:
T = 3.17 s
Explanation:
Given that,
The length of the pendulum, l = 2.5 m
We know that the period of oscillation of the pendulum is given by :
[tex]T=2\pi \sqrt{\dfrac{l}{g}}[/tex]
Where
g is the acceleration due to gravity
[tex]T=2\pi \sqrt{\dfrac{2.5}{9.8}}\\\\T=3.17\ s[/tex]
So, the period of oscillation is equal to 3.17 s.

howA 4400 Kg Track Travelling at Intial speed 52m\s can be stopeed in 42 sec. By Gently Break , also the track can be stoped in 7.6 m\s if the driver hit the wall
Answer:
-4,651.42N
Explanation:
Since we are not asked what to find, we can calculate the force applied by the track as shown;
F = ma
F = m(v-u)/t
Substitute the given value
F = 4400(7.6-52)/42
F = 4400(-44.4)/42
F = -4,651.43N
Hence the required force is -4,651.42N
Spherical mirror is a
Answer:
Spherical mirror is a mirror with a curved reflecting surface.
There are two spherical mirrors -
Concave andConvexConcave Mirror - A spherical mirror , whose reflecting surface is curved inwards , that is , faces towards the centre of the sphere , is called concave mirror.
Cnovex Mirror - A spherical mirror whose reflecting surface is cirved outwards is called convex mirror.
Explanation:
Points of difference :
The reflecting surface of the concave mirror is bulged inwards . But the reflecting surface of the convex mirror is bulged outwards.Concave mirror produces real and inverted images ( except when the object is placed between F and P , concave mirror produces virtual and erect image ) . But is convex mirror always produces virtual and erect images.The image formed by the concave mirror may be enlarged or diminished, according to the position of the object. The image formed by convex will be always diminished.The net force of a heavy, stationary box is?
