which ecosystem is most resilient to change due to its high diversity?(1 point)
Answers
The tropical rainforest ecosystem is most resilient to change due to its high diversity.
Tropical rainforests are characterized by high biodiversity, which includes a wide variety of plant and animal species.
This diversity allows for increased stability and resilience, as the numerous species can fill various ecological roles and adapt to changes in the environment more effectively than ecosystems with lower diversity.
Ecosystems with high biodiversity are generally more resilient to change due to their ability to distribute ecological functions and maintain stable food webs.
Summary: The high diversity of species in tropical rainforests makes them the most resilient ecosystem to change.

A 5.0 kg bike moving 10 m/s comes to a complete stop in 2 seconds. What is the average force of the brakes on the bike?
Answers
Answer:
25 N
Explanation:
Force : This is defined as the product of mass and acceleration. The unit of force is Newton or kgm/s².
From the question,
F = ma......................... Equation 1
Where F = Force of the brake, m = mass of the break, a = acceleration.
But,
a = v/t.................. Equation 2
where v = velocity, t = time.
Substitute equation 2 into equation equation 1
F = m(v/t)................ Equation 3
Given: m = 5.0 kg, v = 10 m/s, t = 2 seconds
F = 5(10/2)
F = 25 N.
Hence the average force of the brakes on the bike is 25 N
Answer:
The average force of the brakes on the bike is 25.0 N
Explanation:
The parameters given in the question are,
Mass, m = 5.0kg
Initial velocity, u = 10 m/s
Time, t = 2 sec
Since the bike came to a complete stop, then
Final velocity, v = 0 m/s
To determine the average force of the brakes on the bike; From Newton's second law of motion, Force is given as
F = ma
Where F is the force in N (Newtons)
m is the mass in kg
and a is acceleration in m/s²
Hence, we will first determine the acceleration.
From one of the equations of kinematics for linear motion,
\(v = u + at\)
Then, \(a = \frac{v - u}{t\\}\)
Putting the given parameters into the above equation, we get
\(a = \frac{0 - 10}{2}\)
\(a = \frac{-10}{2}\\ a = - 5\)m/s²
The negative sign indicates deceleration since the bike came to a stop,
Hence, \(a = 5\) m/s²
From,
F = ma
F = 5.0 × 5
F = 25.0 N

Given that the mass of the earth is 5.97 X 10 24 kg and its radius length is 6.34 X 10'
6 m Then find the tension of gravitational field of earth to a body of mass 1000 kg putting on the ground surface
Answers
The tension of the gravitational field of the earth to a body of mass 1000 kg putting on the ground surface is 9810 N.
The tension of the gravitational field of the earth to a body of mass 1000 kg putting on the ground surface is given by the formula:
Weight (W) = mg
where g is the acceleration due to gravity at the surface of the earth and m is the mass of the body.
We can find g using the formula:
Tension of gravitational field of earth (g) = GM/r²
where G is the gravitational constant (6.67 x 10⁻¹¹ Nm²/kg²), M is the mass of the earth (5.97 x 10²⁴ kg), and r is the radius length of the earth (6.34 x 10⁶ m).
So, substituting the given values, we have:
g = (6.67 x 10⁻¹¹Nm²/kg² × 5.97 x 10²⁴ kg)/(6.34 x 10⁶ m)²g = 9.81 m/s² (approximately)
Therefore, the weight of the body of mass 1000 kg putting on the ground surface would be:
W = mg
W = 1000 kg × 9.81 m/s²
W = 9810 N

Un delfín nada en el mar, a una profundidad tal que experimenta es de 2,22 x 10⁵ PA. Si la densidad del agua del mar es de 1030kg/m³, ¿A qué profundidad nada el delfín?
Answers
Answer:
El delfín nada a una profundidad de 22 m
Explanation:
El principio fundamental de la hidrostática establece que la presión en un punto del interior de un fluido (presión hidrostática) es directamente proporcional a su densidad, a la profundidad que se encuentre dicho punto y a la gravedad del sitio en el que se encuentre el fluido.
Esto se expresa como:
P=ρ⋅g⋅h
donde:
P es la presión en un punto del fluido. ρ es la densidad del fluido .g es la gravedad del lugar donde se encuentre el fluido. h es la profundidad.En este caso:
P= 2.22*10⁵ Paρ= 1,030 \(\frac{kg}{m^{3} }\)g= 9.8 \(\frac{m}{s^{2} }\)h= ?Reemplazando:
2.22*10⁵ Pa= 1,030 \(\frac{kg}{m^{3} }\) * 9.8 \(\frac{m}{s^{2} }\) * h
Resolviendo:
\(h=\frac{2.22*10^{5} Pa}{1,030\frac{kg}{m^{3} }*9.8 \frac{m}{s^{2} }}\)
h= 21.993 m ≅ 22 m

D) Heat and pressure
Answers
The correct answer is Heat and pressure.
Weathering and erosion have the potential to transform sedimentary rock back into sediment. It could also produce a different kind of rock. It may transform into metamorphic rock if it is buried deep enough in the crust to be exposed to higher temperatures and pressures.
Sedimentary rocks frequently exhibit recognisable bedding or layering.
Although they began as a different kind of rock, metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.

The ____ of a telescope is a measure of its ability to show fine detail and depends on the diameter of the objective.
Answers
The resolution of a telescope is a measure of its ability to show fine detail and is influenced by the diameter of the objective.
The resolution of a telescope refers to its ability to distinguish and separate two closely spaced objects or features. It is determined by the diameter of the objective lens or mirror of the telescope. The larger the diameter of the objective, the higher the resolution of the telescope.
The resolution of a telescope is limited by diffraction, a phenomenon that causes light waves to spread out as they pass through a small aperture or aperture-like structure such as the objective of a telescope. This spreading of light leads to a blurring effect and reduces the ability to resolve fine details.
The resolving power of a telescope is described by the formula:
\(Resolution = 1.22 * (wavelength of light) / (diameter of the objective)\)
The constant factor of \(1.22\) is derived from the theory of diffraction and determines the smallest angle at which two objects can be distinguished. A larger diameter objective allows more light to be collected and reduces the impact of diffraction, resulting in better resolution and the ability to see finer details in celestial objects.

My primary mode of transportation is a car, and its energy efficiency is typically around 3 kW-hrs per 100 person-km.
As my primary mode of transportation, I rely on a car for commuting and traveling. While cars offer convenience and comfort, they are not the most energy-efficient option. On average, a car consumes approximately 3 kW-hrs of energy per 100 person-km. This energy consumption includes the fuel or electricity required to power the vehicle and accounts for the energy losses during the generation, distribution, and storage processes.
The energy efficiency of a car can vary depending on several factors, including the vehicle's make and model, driving conditions, and driving habits. Factors such as speed, acceleration, and braking can impact fuel consumption and efficiency. Additionally, the type of fuel or power source used by the car influences its energy efficiency. Electric vehicles (EVs) tend to have higher energy efficiency compared to traditional internal combustion engine (ICE) vehicles, as they convert a higher percentage of their energy into forward motion.

Answer:
Higher force would be required to stop 5 kg of ball
Explanation:
The force required to stop a moving object depends on its momentum.
The momentum for 8 kg of rolling ball is = 8 kg * 0.2 m/s = 1.6 kgm/s
The momentum for 5 kg of rolling ball is = 8 kg * 1.0 m/s = 5 kgm/s
