Como cambia la magnitud de la fuerza electrica entre dis cargas puntuales conforme aumenta la distancia

We must remember that all molecules have zero net charge. To solve this question lets take a look at the periodic table.

We can see that Chlorine belongs to the column 17. That means its charge is negative one, i.e., -1. We can write:

We also can see that Tin is in 14th column but that doesn't tell us much about it electric charge.

To solve this we must use the "fence trick".

Since the molecule has zero net charge, that means the sum of all charges must be zero. Using the "fence trick" we have to cross the numbers that appear on the molecule. We can write:

So the charge of the transition metal is:

Answer:

x = - 8 atau 3

Explanation:

3ˣ² × 3⁵ˣ = 3²⁴

Penarikan:

Mᵃ × Mᵇ = Mᵃ⁺ᵇ

3ˣ² × 3⁵ˣ = 3ˣ²⁺⁵ˣ

Karena itu

3ˣ² × 3⁵ˣ = 3²⁴

3ˣ²⁺⁵ˣ = 3²⁴

x² + 5x = 24

Mengatur kembali

x² + 5x - 24 = 0

Pemecahan dengan faktorisasi

x² - 3x + 8x - 24 = 0

x (x - 3) + 8 (x - 3) = 0

(x + 8) (x - 3) = 0

x + 8 = 0 atau x - 3 = 0

x = - 8 atau x = 3

Karena itu,

x = - 8 atau 3

a) The isocost curve equation is G = (20000 - 100C)/500. b) The isocost curve equation is G = (30000 - 100c)/500. c) The isocost curve equation is G = (20000 - 100C)/375. d)  The isocost curve equation is G = (20000 - 120C)/500.

To draw the isocost curve showing the different combinations of gas and coal, we need to use the cost per unit values for coal and gas, as well as the given expenditure (TC) and the changes in expenditure or prices.

Let's denote the quantity of coal as C and the quantity of gas as G. The cost per unit of coal is 100, and the cost per unit of gas is 500.

(a) Initial expenditure (TC) of 20000:

To find the combinations of gas and coal that can be purchased with an initial expenditure of 20000, we can use the following isocost equation

TC = 100C + 500G

We can rearrange the equation to solve for G in terms of C

G = (TC - 100C) / 500

Now we can plot the isocost curve with TC = 20000 using the equation above.

(b) Expenditure (TC) increases by 50%

If the expenditure increases by 50%, the new expenditure (TC_new) becomes 1.5 × TC = 1.5 × 20000 = 30000.

We can use the same isocost equation as before, but with the new expenditure value:

TC_new = 100C + 500G

Rearranging the equation to solve for G

G = (TC_new - 100C) / 500

Now we can plot the isocost curve with TC_new = 30000.

(c) Gas price reduced by 25%:

If the gas price is reduced by 25%, the new cost per unit of gas (Gas_new) becomes 0.75 × 500 = 375.

We can use the original isocost equation, but with the new cost per unit value:

TC = 100C + 375G

Rearranging the equation to solve for G

G = (TC - 100C) / 375

Now we can plot the isocost curve with the reduced gas price.

(d) Coal price rises by 20%

If the coal price rises by 20%, the new cost per unit of coal (Coal_new) becomes 1.2 × 100 = 120.

We can use the original isocost equation, but with the new cost per unit value:

TC = 120C + 500G

Rearranging the equation to solve for G:

G = (TC - 120C) / 500

Now we can plot the isocost curve with the increased coal price.

By plotting these isocost curves on a graph with G on the y-axis and C on the x-axis, we can visualize the different combinations of gas and coal that can be purchased at the given expenditures or price changes.

The maximum force, in newtons, can you exert horizontally on the crate without moving it is 515.025 N. If you continue to exert this force once the crate starts to slip, its acceleration will be, in 1.962 meters per square second.

(A) To find the maximum force without moving the crate, we can use the formula for static friction: \(f_{static} = f_s * N\), where \(f_s\) is the coefficient of static friction and N is the normal force. In this case, N = m * g (mass times gravity), so N = 105 kg * 9.81 \(m/s^2\) = 1030.05 N. Therefore, the maximum force is \(f_{static\) = 0.5 * 1030.05 N = 515.025 N.

(B) Once the crate starts to slip, we can use the formula for kinetic friction: \(f_{kinetic\) = \(f_k * N\), where \(f_k\) is the coefficient of kinetic friction. In this case, \(f_{kinetic\) = 0.3 * 1030.05 N = 309.015 N. To find the acceleration, use Newton's second law: F = m * a. Rearrange to find a: a = F / m. The net force is the applied force minus the kinetic friction, so a = (515.025 N - 309.015 N) / 105 kg = \(1.962 m/s^2.\)

A) The maximum force that can be exerted horizontally on the crate without moving it is 514.53 N

B) Once the crate starts to slip, its acceleration will be 1.05 m/s².

(A) The maximum force that can be exerted horizontally on the crate without moving it can be found using the equation:

Fs = μsN, where Fs is the force of static friction, μs is the coefficient of static friction, and N is the normal force.

N = mg, where m is the mass of the crate and g is the acceleration due to gravity.

Substituting the given values, we get:

Therefore, the maximum force that can be exerted horizontally on the crate without moving it is 514.53 N.

(B) Once the crate starts to slip, the force of friction changes to the force of kinetic friction, which is given by:

Fx = μkN, where Fx is the force of kinetic friction and μk is the coefficient of kinetic friction.

Substituting the given values, we get:

The net force acting on the crate is given by the difference between the applied force and the force of friction:

where Fa is the applied force.

The acceleration of the crate can be found using the equation:

Substituting the values, we get:

Substituting the maximum force that can be exerted without moving the crate, we get:

Therefore, once the crate starts to slip, its acceleration will be 1.05 m/s².

The electric field at a point halfway is 18.37 x 10⁵ N/C.

We need to know about the electric fields to solve this problem. The electric field produced by a single-point positive charge is a radial field, whose strength is given by the equation

E = k.Q/r²

where E is the electric field, Q is the charge and r is the radius.

From the question above, we know that

k = 9 x 10⁹ Nm²/C²

Q1 = -5μC = -5 x 10¯⁶ C

Q2 = 4μC = 4 x 10¯⁶ C

x = 21 cm = 0.21 m

from midpoint (r = 0.105 m)

The electric field directly outward from Q2 to Q1 so that the total electric field between the charges will be added up.

Etotal = E1 + E2

Etotal = k.Q1/r² + k.Q2/r²

Etotal = k/r² x (Q1 + Q2)

The new temperature of the gas inside the cylinder is 594 K.

The temperature of a gas is directly proportional to its pressure when the volume is constant. This relationship is expressed mathematically in Charles' law, which states that for a fixed mass of gas at a constant volume, the temperature and pressure of the gas are directly proportional. Therefore, if a cylinder of fixed mass of petroleum gas at a temperature of 24 °C had a pressure inside the cylinder of 100 KPa above the atmospheric pressure, when exposed to an open flame, the pressure inside the cylinder increased to 300 KPa above atmospheric pressure. To calculate the new temperature of the gas inside the cylinder assuming no change in volume, we use the combined gas law equation which relates the pressure, volume, and temperature of a gas. The equation is given as:P1V1/T1 = P2V2/T2Where P1V1/T1 = (100 + 100)kPa = 200 kPa P2V2/T2 = (100 + 300) kPa = 400 kPa, and T1 = 24 + 273 = 297 KThe volume of the gas is constant, which implies that V1 = V2; hence we can write the equation above as follows:V/T = constant, where V is volume, and T is temperatureTherefore, V1/T1 = V2/T2 and substituting the values we have, we can solve for T2 as follows:V1/T1 = V2/T2 => T2 = T1 × (P2/P1)T2 = 297K × (400/200)T2 = 594K

When vast air masses with disparate temperatures and densities collide, cyclonic storms are produced. A weather front develops as the warmer, lower-density air mass rises and the colder air mass descends.

Low pressure zones are where cyclones can originate. This occurs as a result of the tendency of winds that blow from regions of high pressure to regions of low pressure to blow toward the center of a low pressure area.

Since the cubes have the same mass and specific heat capacity, the only difference is the change in temperature. Therefore, both cubes gained the same amount of heat. Q = mcΔT where Q is the heat gained, m is the mass of the cube, c is the specific heat capacity, and ΔT is the change in temperature.
Given that both cubes are pure tungsten and have the same specific heat capacity, they will also experience the same temperature change of 10 K.
