Answer:

La fuerza que se ejerce entre las dos cargas es 2880 N.

Explanation:

La ley de Coulomb indica que los cuerpos cargados sufren una fuerza atractiva o repulsiva al acercarse. La fuerza es atractiva si las cargas son del signo opuesto y repulsión si son del mismo signo. El valor de la fuerza es proporcional al producto del valor de sus cargas e inversamente proporcional al cuadrado de la distancia que los separa. Esto se expresa matemáticamente como:

\(F=k*\frac{Q*q}{r^{2} }\)

Explanation:

The escape velocity at the event horizon of a black hole is 300,000 km/s, which is the speed of light.

The escape velocity is the minimum velocity required for an object to escape the gravitational pull of a celestial body. It is directly proportional to the mass of the celestial body and inversely proportional to the distance from the center of the body. The escape velocity at the event horizon of a black hole is calculated using the formula v = √(2GM/r), where G is the gravitational constant, M is the mass of the black hole, and r is the radius of the event horizon.

The event horizon is the point of no return, beyond which nothing, not even light, can escape. Given the mass of a black hole, the event horizon can be calculated, and then the escape velocity can be determined. For a black hole, the escape velocity at the event horizon is approximately 300,000 km/s, which is the speed of light.

If an object is speeding up its acceleration can be positive or negative depending on the direction of motion.

According to mathematics, a negative acceleration indicates that the velocity will be subtracted, while a positive acceleration indicates that the velocity will be increased.

In physics,

A positive acceleration indicates a rising velocity over time.

Negative acceleration describes a speed decrease over time.

A bus or car going at an accelerating rate is said to have positive acceleration.

We may say that it is speeding up in the direction it is moving.

The maximum possible value for distance, d is calculated as equal to 80.9 meters. This means that if the car is farther away than 80.9 meters, the bear will catch up to the tourist before the tourist reaches the car.

The tourist's speed is given as 5.66 m/s, so we can find the time it takes for the tourist to reach the car by dividing the distance d by 5.66 m/s: time = d / 5.66

Now we need to figure out how far the bear can run in this amount of time. We can use the formula: distance = speed x time

The bear's speed is given as 7.46 m/s, and the time it takes for the tourist to reach the car is d / 5.66. So the distance the bear can run in this time is: distance = 7.46 x (d / 5.66)

Now we can set up an equation to find the maximum possible value for d. We know that the bear starts 25.9 m behind the tourist, and the tourist reaches the car safely, which means the bear doesn't catch up. So the maximum distance the bear can run is equal to the distance between the tourist and the car, which is: d - 25.9

Setting this equal to the distance the bear can run, we get: d - 25.9 = 7.46 x (d / 5.66)

Now we can solve for d: d - 25.9 = 1.32d
0.32d = 25.9

Thus, d = 80.9

So, the maximum possible value for d is 80.9 meters.

The chi-square test assumes that the variables being analyzed are measured at a nominal or ordinal level of measurement.

In statistics, the level of measurement refers to the nature and properties of the data being collected. There are four levels of measurement: nominal, ordinal, interval, and ratio. Nominal and ordinal levels are considered categorical, while interval and ratio levels are considered numerical. The chi-square test is specifically designed for analyzing categorical data, where the observations can be classified into distinct categories or groups. It is used to determine whether there is a significant association or relationship between two categorical variables.

The test calculates the difference between the observed frequencies and the expected frequencies under the assumption of independence between the variables. It compares the observed and expected frequencies using a chi-square statistic and determines the p-value to assess the statistical significance of the association. Therefore, the chi-square test assumes that the variables being analyzed are measured at a nominal or ordinal level because it deals with categorical data and evaluates the relationship between different categories or groups.

The flaw in the experiment on water recycling is that the student did not see water dripping off the glass plate as expected. To correct this flaw, the student should use a cold glass plate instead of a hot glass plate.

The correct option to the given question is option 4.

When the student holds the hot glass plate above the beaker, the water vapor in the atmosphere will come into contact with the cold surface of the plate and condense, forming water droplets. However, if the glass plate is already hot, it will not be able to cool down the water vapor quickly enough for condensation to occur.

By using a cold glass plate, the temperature difference between the plate and the water vapor will be greater, allowing for faster condensation. This will result in water droplets forming on the glass plate and dripping off, demonstrating the process of water recycling through the atmosphere.

Therefore, the correct method to correct the flaw in this experiment is to use a cold glass plate instead of a hot glass plate. This will enable the student to observe water droplets on the glass plate as expected.

Explanation:

1)Melting:

Melting is the process by which a substance changes from the solid phase to the liquid phase. ... Melting occurs when the internal energy of a solid increases, usually through the application of heat or pressure, such that the molecules become less ordered.

2) liquefication:

In physics and chemistry, the phase transitions from solid and gas to liquid (melting and condensation, respectively) may be referred to as liquefaction. The melting point (sometimes called liquefaction point) is the temperature and pressure at which a solid becomes a liquid.

3) vaporization:

Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.

4) Sublimation occurs as molecules of a substance in the solid state go to the vapor state directly, rather than through the liquid state. ... ⭕In terms of the kinetic molecular theory, we know that molecules are in constant random motion, even when the substance is below the melting point.

The jovian planets bulge around the equator, that is, have a "squashed" appearance is C) Their rapid rotation flings the mass near the equator outward.

The jovian planets, such as Jupiter and Saturn, have a "squashed" or bulging appearance due to their rapid rotation. The centrifugal force generated by their rotation causes the mass near the equator to be pushed outward, creating a noticeable bulge. This effect is similar to how the equator of Earth bulges slightly due to its rotation.

While options A, B, and D may have some influence on the overall shape of jovian planets, it is the rapid rotation that primarily accounts for their flattened appearance.

The massive size of these planets (option A) contributes to their gravitational influence on their moons and rings, but it does not directly cause the equatorial bulge. Internal heat sources (option D) primarily affect the planets' overall structure and atmosphere, rather than their shape.

Answer:

6.25 sec

Explanation:

Given: initial velocity = 15 m/s final velocity = 25 m/s, and distance = 125 m

average velocity = (25 + 15)/2

Distance(D) = Rate(R) x Time(T)

125 = ((25 + 15)/2) x T

125 = 20T

T = 6.25 sec

Hence the required time to achieve final speed is 6.25 sec

Answer:

See below

Explanation:

Here is another way

d = vo t + 1/2 a t^2        a = change vel /change t =  10/t

125 = 15 t + 1/2 (10/t) t^2

125 = 20 t

t = 125/20 = 6.25 s

The magnitude of the acceleration due to gravity on this distant planet is approximately 9.8 m/s².

To determine the acceleration due to gravity on the distant planet, we can follow these steps:

1. Find the time period (T) of one oscillation:
Since the pendulum completes 100 oscillations in 360 seconds, the time period for one oscillation is:
T = 360 s / 100 oscillations = 3.6 s

2. Use the formula for the period of a simple pendulum:
T = 2π√(L/g)
where L is the length of the pendulum (1.20 m) and g is the acceleration due to gravity.

3. Solve for g:
Square both sides of the equation:
T² = 4π²(L/g)
Now, isolate g:
g = 4π²L/T²

4. Substitute the known values:
g = (4 * π² * 1.20 m) / (3.6 s)²
g ≈ 9.8 m/s²

The magnitude of the acceleration due to gravity on this distant planet is approximately 9.8 m/s².
