What is the distance between (-1,4) and (-5,0) in simplest radical form

Answer:

transformers

Explanation:

A transformer is a device that increases or decreases voltage.

A change in temperature frequently causes substances to change phases. Most substances are solid at low temperatures; as the temperature rises, they become liquid; and at still greater temperatures, they become gaseous.

Melting is the conversion of a solid into a liquid (an older term that you may see sometimes is fusion). Solidification is the process where a liquid turns into a solid. The melting point, or the temperature at which a pure substance begins to melt, is a property of that substance. A solid must expend energy to become a liquid. A specific quantity of energy is required by every pure substance in order to transform from a solid to a liquid. This amount is known as the substance's enthalpy of fusion (or heat of fusion).

By using the blackbody radiation formula, the temperature of the filament inside the bulb is changed by a factor of 10⁰'²⁵.

We need to know about black body radiation to solve this problem. The energy radiated by a black body object is proportional to the area and the fourth power of temperature. It can be determined as

P = A . e . σ . T⁴

where P is power, A is surface area, e is emissivity, σ is Stefan Boltzmann's constant ( 5.67 x 10¯⁸ W/m²K⁴) and T is temperature.

From the question above, we know that

P1 = 10 watt

P2 = 100 watt

T1 = T1

By using the black body radiation formula, the ratio of temperature is

T1⁴ / T2⁴ = P1 / P2

Hence,

T1⁴ / T2⁴ = P1 / P2

T1⁴ / T2⁴ = 10 / 100

T1⁴ / T2⁴ = 1 / 10

T2⁴ = 10T1⁴

T2 = ⁴√(10T1⁴)

T2 = T1 x 10⁰'²⁵

Thus, the temperature of the filament inside the bulb is changed by a factor of 10⁰'²⁵.

The minimum index of refraction of the prism is 1.414.

What does light ray is incident mean?

Light ray incident is a term used to describe when a light ray strikes a surface. This can refer to light from any source, such as the sun, a light bulb, or a laser. When light rays are incident on a surface, they may be reflected, absorbed, or transmitted. The behavior of the light depends on the properties of the surface, such as its color, texture, and composition.

This double internal reflection requires that the angle of incidence (45º) at the 1st prism side is at least = critical angle. This reflected ray then meets the other prism side at the same angle of incidence (45º). so we only need to consider the first internal reflection.

Applying [ n sin i = constant ] to the prism-air boundary.

(np= ref.index for prism material, nₒ = ref.index for air =1.0 )

At a critical angle of incidence 45º, external angle = 90º

np sin 45 = nₒ sin90

np = nₒ sin90 / sin45=1 x 1 / 0.7071

np(min) = 1.414

In 6 hours the total decrease in temperature is 15 degrees Celcius and it reaches -18 degrees Celcius.

Option A is the correct answer.

Given that the temperature at noon is -3 degrees Celsius.

The temperature is expected to decrease by 2.5 degrees Celsius each hour until the temperature reaches -18 degrees Celsius.

Current temperature = \(-3^\circ \;\rm C\).

D.physical model

Explanation:

it is the evolution of butterfly

The athlete is pushing with a force of 24.5 N.

When an athlete compresses a horizontal spring with a spring constant 350 N/m attached to a wall, the force exerted by the athlete can be calculated using Hooke’s law, which states that the force required to extend or compress a spring by some distance x from its original position is directly proportional to that distance x (F = kx). Where, k is the spring constant and it is given as 350 N/m. x is the distance by which the spring is compressed, which is given as 7.0 cm. Therefore, the force applied by the athlete can be calculated as: F = kx

= (350 N/m)(0.07 m)

= 24.5 N Hence, the athlete is pushing with a force of 24.5 N.

To calculate the force applied by the athlete on the horizontal spring attached to the wall, Hooke's law formula is used. Hooke's law states that the force required to extend or compress a spring is directly proportional to the distance x from its original position. It can be expressed mathematically as: F=kx where F is the force applied, k is the spring constant and x is the distance by which the spring is compressed. The spring constant is given as 350 N/m, and the distance by which the spring is compressed is given as 7.0 cm. On substituting the values in the above formula, we get: F = kx

= (350 N/m)(0.07 m)

= 24.5 N Hence, the athlete is pushing with a force of 24.5 N.

The mean and variance for a Bernoulli random variable with p = 0.73 are 0.73 and 0.1971, respectively.

The values and calculate the mean and variance for the given distributions:

For the Bernoulli distribution:

The parameter p (probability of success) is given as 0.73.

The mean (μ) of the distribution is equal to p.

Mean (μ) = p = 0.73

To find the variance (σ²), we can use the formula: σ² = p(1 - p).

Variance (σ²) = 0.73(1 - 0.73) = 0.73 × 0.27 = 0.1971

For the binomial distribution with parameter p = 0.34 and sample size n:

The mean (μ) of the binomial distribution is given by μ = np.

Mean (μ) of X = np = n × 0.34

The variance (σ²) of the binomial distribution is given by σ² = np(1 - p).

Variance (σ²) of X = n × 0.34 × (1 - 0.34)

Now, considering the random variable Y defined as Y = nX:

Two examples of waves reflecting are: A voice echo and  Your image in a mirror. Hence, option (B) and (D) is correct.

A wave is the regular, coordinated transmission of disturbances from one location to another. The waves that travel on water's surface are the most well-known, but waves also exist in sound, light, and the movement of subatomic particles. The disturbance periodically oscillates with a set frequency and wavelength in the simplest waves.

When two different media come together at an interface, a wavefront might change direction so that it returns to the first medium, which is known as reflection. The reflection of light, sound, and water waves are typical examples.

The correct prediction about the angular momentum and rotational kinetic energy of the sphere-rod system immediately before the collision and immediately after the collision is: Before the collision, the sphere has linear momentum (mass mo multiplied by velocity to) while the rod has zero angular momentum since it is at rest.

After the collision, the sphere and rod form a single system, and the conservation of angular momentum dictates that the final angular momentum of the system should equal the initial angular momentum of the sphere. Therefore, the sphere-rod system will have non-zero angular momentum after the collision.

Regarding rotational kinetic energy, before the collision, the sphere has linear kinetic energy (1/2 mo * to²) and the rod has zero rotational kinetic energy. After the collision, the sphere-rod system will have rotational kinetic energy (as they both rotate around the pivot with a common angular velocity). Due to the inelastic nature of the collision, some linear kinetic energy from the sphere will be converted to rotational kinetic energy in the sphere-rod system, but not all of it, as some energy will be lost as heat and sound during the collision.

The beyond-use-date for a solution would be 1/2020. The beyond-use-date for the solution containing water would be determined by the ingredient with the earliest expiration date, which is Ingredient B with an expiration date of 1/2020.

To determine the beyond-use-date for the solution, we need to identify the ingredient with the earliest expiration date. The beyond-use-date should not extend beyond the expiration date of any of the active ingredients.

Ingredient A: Expiration date 10/2025

Ingredient B: Expiration date 1/2020

Ingredient C: Expiration date 3/2021

Since Ingredient B has the earliest expiration date (1/2020), the beyond-use-date for the solution cannot exceed this date. Therefore, the beyond-use-date for the solution containing water would be 1/2020.

The beyond-use-date for the solution would be determined by the ingredient with the earliest expiration date, which in this case is Ingredient B with an expiration date of 1/2020. It is important to adhere to the expiration dates of the active ingredients to ensure the effectiveness and safety of the solution.
