The ranking of the gravitational force acting on the asteroid are asteroid: sun, asteroid: earth, asteroid: moon, asteroid: asteroid, asteroid: hydrogen atom

What is an asteroid explain?

An asteroid is a small, rocky object that orbits the Sun. Asteroids are much smaller than planets, and are composed mostly of rock and minerals. They range in size from less than 1 meter to hundreds of kilometers across. Most asteroids are found in a region of space between the orbits of Mars and Jupiter known as the asteroid belt. On average, about 100 tons of material from asteroids and comets hits Earth's atmosphere each day. Most of this material is small dust-sized particles that burn up in the atmosphere before they reach the ground.

The gravitational force solely depends on the product of the masses because the distance is the same in each of the five scenarios. The mass of the object on the right determines the relative strength of gravitational force because the same asteroid is in each of the five scenarios on the left. Explore what transpires if we inquire about the gravitational force operating on the object on the right in Part B.

Therefore, asteroid: sun, asteroid: earth, asteroid: moon, asteroid: asteroid, asteroid: hydrogen atom are the answers.

Answers

The metal's crystal structure is FCC.

Finding a metal's density to atomic weight ratio and lattice parameter value will reveal the metal's crystal structure. The ratio of density to atomic weight is about equivalent to the quantity of atoms per unit cell in the crystal structure if the metal has a density of 19.302 g/cm3 and an atomic weight of 196.97 g/mol.

One atom per lattice point in a cubic structure with a lattice parameter of 4.0786 corresponds to a simple cubic (SC), body-centered cubic (BCC), or face-centered cubic (FCC) structure. The lattice parameter and density to atomic weight ratio are most consistent with an FCC crystal structure.

A container with volume 1.54 L is initially evacuated. Then it is filled with 0.221 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy.
If the root-mean-square speed of the gas molecules is 182 m/s , what is the pressure of the gas?

Answers

The pressure of the gas in a container with a volume of 1.54 L is initially evacuated. Then it is filled with 0.221 g of N2 is 1619Pa.

A gas with a small density and at a sufficiently high temperature so that the interaction between its particles can be neglected can be considered an ideal gas. In this case, the pressure, volume, and temperature of the gas are related as follows:

PV=mMRT, where m is the mass of the gas and M is the molar mass of the gas. The pressure of the gas can be found using the ideal gas law:p =mRT/MV.

The temperature of the gas can be found from the RMS speed of the molecules of nitrogen, which is given by: vrms=√3RT/M. Solving for the temperature, we obtain: T= Mv² / 3 R. And pressure is P= mv² /3V. So P=[ 0.221×(184)²]/ 3×1.54 = 1619 Pa.

Unscramble the terms in italics to complete the sentences below. Write the terms on the lines provided. 5. In dry regions where sheep and cattle eat the grasses, reggianvorz increases soil erosion.​

Answers

The term which describes the increased soil erosion in the regions where sheep and cattle eat the grasses and reggianvorz is called overgrazing.

What is overgrazing ?

Overgrazing happens when livestock and other grazers (such as wildlife) consume more plant biomass than the vegetation can replenish in a reasonable amount of time, exposing the soil and lowering the vegetation's potential for production.

The exposure of the soil might hasten the potential for processes of water and wind erosion, which can result in soil losses. Less water infiltration into the soil might result in slower plant growth due to accelerated erosion processes and soil compaction caused by grazing animals.

Because less plant biomass is accessible as litter due to ongoing overgrazing, less soil organic matter, nutrients, and biotic activity are added to the soil. This causes the soil structure to deteriorate, which lowers the soil's capacity to store water and raises the risk of erosion.

Therefore, the term describing the given action is overgrazing.

How much work must we do on an electron to move it from point A, which is at a potential of +50V, to point B, which is at a potential of -50V, along the semicircular path shown in the figure? Assume the system is isolated from outside forces

Answers

[tex]1.602 x 10^-17[/tex] is the work must we do on an electron to move it from point A, , to point B, that is at a potential of -50V, along the semicircular path.

What is electron?

In order to move the electron from point A to point B, we need to do work on it to overcome the electric potential difference between the two points. Since the two points have potentials of +50V and -50V respectively, the total potential difference is 100V.

Since the electric field is conservative, the work done by it depends only on the potential difference between points A and B and not on the path taken. The potential difference between points A and B is given by:

ΔV = V_B - V_A = -50 V - (+50 V) = -100 V

To move an electron from point A to point B, we need to do work on it equal to the change in its potential energy. The potential energy of an electron in an electric field is given by:

U = qΔV

where q is the charge of the electron, and ΔV is the potential difference.

The charge of an electron is:

q = -1.6 x [tex]10^{-19 }[/tex]C

Substituting the values, we get:

U = (-1.6 x [tex]10^{-19 }[/tex] C) x (-100 V)

U = 1.6 x [tex]10^{-19 }[/tex]

Therefore, we need to do work on the electron equal to 1.6 x 10^-17 J to move it from point A to point B along the given semicircular path.

Answers

The electric potential at the origin is 1.079 x 10^5 V.

What is electric potential?

Electric potential is a measure of the electric potential energy per unit charge in an electric field.

The electric potential at the origin can be calculated using Coulomb's law and the principle of superposition. The electric potential at a point due to a single charge is given by:

V = k * q / r

where

k is the Coulomb constant (8.99 x 10^9 Nm^2/C^2)q is the charge r is the distance from the point to the charge

At what time do the wheels leave the ground?c. For safety reasons, in case of an aborted takeoff, the runway must be three times the takeoff distance. Can an A320 take off safely on a 2.5-mi-long runway?

Answers

The acceleration is expressed as the product of the change in time and the change in velocity, and it is 2.3 m/s. 34.78 seconds pass before the wheels lift off the ground.

How do velocity and speed differ?

Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion.

Taking the first interval, we find

a = Δvx/Δt

a = 23m/s/10m/s

a = 2.3m/s

By dividing the acceleration in m/s2 by the value of g, or the acceleration of gravity (9.81 m/s2), we may determine the jet's acceleration in g's.

ag = a/g

2.3/9,8

ag = 0.33g

When the jet reaches its takeoff velocity, which is 80 m/s, the wheels come off the ground.

The jet's velocity is zero at time t=0 s. Since we are aware that the acceleration is constant (a=2.3 m/s2), we can use the equation to determine the time t at which the jet achieves a velocity of vf=80 m/s.

vf = vi + at

Rigid rods of negligible mass lying along the y axis connected three particles. The system rotates about the x axis with an angular speed of 2.00 rad/s. Find the total rotational kinetic energy evaluated from 1/2 Iω ^2

Answers

The total rotational kinetic energy of the system can be found by evaluating the above expression using the given values of m, r, and ω [tex]KE = 1/2 * (m1 * r1^2 + m2 * r2^2 + m3 * r3^2) * (2.00 rad/s)^2[/tex]

The total rotational kinetic energy of a system can be found by evaluating the expression 1/2 Iω^2, where I is the moment of inertia of the system and ω is its angular velocity. In this case, the moment of inertia of the system can be found by adding the moments of inertia of each particle and the connecting rods.

Since the rods have negligible mass, their moment of inertia is also negligible and can be ignored. The moment of inertia of each particle is given by the formula:

I = mr^2

where m is the mass of the particle and r is its distance from the axis of rotation.

Assuming the particles have masses m1, m2, and m3 and distances from the axis of rotation r1, r2, and r3, respectively, the total moment of inertia is:

[tex]I = m1 * r1^2 + m2 * r2^2 + m3 * r3^2[/tex]

Substituting the given values, we find:

I = (m1 * r1^2 + m2 * r2^2 + m3 * r3^2)

Finally, substituting the moment of inertia and angular velocity into the expression for rotational kinetic energy, we find:

KE = 1/2 * I * ω^2

[tex]KE = 1/2 * (m1 * r1^2 + m2 * r2^2 + m3 * r3^2) * (2.00 rad/s)^2[/tex]

So, the total rotational kinetic energy of the system can be found by evaluating the above expression using the given values of m, r, and ω.

An 85 L flexible container holds 3.4 moles of gas. How many moles of gas should be removed to decrease the volume of the container to 40 L?

Answers

1.8 moles of gas should be removed to decrease the volume of the container to 40 L

What is Avogadro's law?

Avogadro's Law states that the volume of a gas is directly proportional to the number of moles (or a number of particles) of gas when the temperature and pressure are held constant.

Given, An 85 L flexible container holds 3.4 moles of gas.

This problem requires Avogadro's law, which states that the amount (moles) of a gas is directly proportional to its volume, such that if the amount increases, the volume increases and vice versa. You correctly determined the formula to use:

V = k×n or. V₁n₁=V₂n₂.

Let "x" be the number of moles in a 40l container

85/40 = x/3.4

Thus,

x = 1.8

Therefore, 1.8 moles of gas should be removed to decrease the volume of the container to 40 L

A 6. 96-nc charge is located 1. 90 m from a 3. 86-nc point charge. Find the magnitude of the electrostatic force that one charge exerts on the other.

Answers

The required electrostatic force when the charges and distance are specified is calculated to be 66.98 × 10⁻⁹ N.

The charge q₁ is given as 6.96 nC.

The charge q₂ is given as 3.86 nC.

Distance r = 1.9 m

The magnitude of the electrostatic force that one charge exerts on the other is to be found out. The force between two charges at a distance is given by the formula,

F = k q₁ q₂/r² = (9 × 10⁹ × 6.96 × 10⁻⁹ × 3.86× 10⁻⁹)/1.9² = 66.98 × 10⁻⁹ N

Thus, the required electrostatic force is calculated to be 66.98 × 10⁻⁹ N.

A heavy dart and a light dart are launched horizontally on a frictionless table by identical ideal springs. Both springs were initially compressed by the same amount. Which of the following statements about these darts are correct?

Answers

The statement which is correct about the lighter dart leaves the spring moving faster than the heavy dart. Option B is correct.

This is because both darts are launched with the same initial elastic potential energy from the compressed springs, but the lighter dart has less mass than the heavier dart. According to the law of conservation of energy, the lighter dart must move faster than the heavier dart in order to have the same amount of kinetic energy as the heavier dart once it leaves the spring.

The initial potential energy is the same for both darts, and since the potential energy is converted to kinetic energy, the lighter dart must have a higher velocity than the heavier dart in order to have the same amount of kinetic energy.

Therefore, option B is correct, while options A, C, D, and E are not, as they do not accurately describe the behavior of the darts in this scenario.
