Explanation:

The work done against gravity to lift the solid rectangular box to its final position is 439,040 J.

Volume of the box can be calculated as follows:Volume = Base area × Height = (2 m × 2 m) × 4 m = 16 m³Since density = Mass/Volume, we can rearrange this formula to find the mass: Mass = Density × VolumeTherefore, the mass of the box is: Mass = 700 kg/m³ × 16 m³ = 11,200 kg

Now, we need to find the work done against gravity to lift the box to its final position. The formula for work done against gravity is: W = F × d × cos θ where W is the work done, F is the force required, d is the distance moved, and θ is the angle between the force and the direction of movement.In this case, the force required is the weight of the box,

which can be calculated using the formula: F = m × g where m is the mass of the box and g is the acceleration due to gravity, which is approximately 9.8 m/s². Therefore: F = 11,200 kg × 9.8 m/s² = 109,760 N The distance moved is the height of the box, which is 4 m. The angle between the force and the direction of movement is 0°, since the force is acting directly upwards.

Therefore, θ = 0°.Substituting these values into the formula for work done against gravity, we get: W = 109,760 N × 4 m × cos 0° = 439,040 J

Answer:

The required second-degree polynomial is:

\(p(x) = 3x^2-5x+5\\\)

Explanation:

We want to find a second-degree(quadratic) polynomial p(x) with the following properties:

\(p(2)=7 ,p'(2)=7 ,p''(2)=6\)

We let the quadratic polynomial be,

\(p(x) = ax^2+bx+c\\\)

Then we get a set of three equations using the given values that is,

                                               \(4a+2b+c=7\\4a+b=7\\2a=6\)

This was obtained using differentiating the polynomial first and then substituting the respected values. The derivatives of the polynomial are as follows:

\(p'(x) = \frac{d}{dx} (ax^2+bx+c) = 2ax+b\\p''(x) = \frac{d}{dx}(2ax+b) = 2a\)

Solving the given set of equations can be achieved as the last equation gives us a=3. Now putting this in the second equation gives us,

\(4\times 3+b=7\\b=7-12=-5\)

Similarly putting a=3 and b=-5 in the first equation gives us,

\(4\times3 + 2(-5)+c=7\\c=7-12+10=5\\\)

Therefore we have discovered all coefficients and thus the required polynomial is:

\(p(x) = 3x^2-5x+5\)

Answer:

Resistencia = 12.5 Ohmios

Explanation:

Dados los siguientes parámetros;

Voltaje = 3.5 Volts

Corriente = 0.28 Amps

Para encontrar el resistencia;

La ley de Ohm establece que a temperatura constante, la corriente que fluye en un circuito eléctrico es directamente proporcional al voltaje aplicado en los dos puntos e inversamente proporcional a la resistencia en el circuito eléctrico.

Matemáticamente, La ley de Ohm viene dada por la fórmula;

Voltaje = corriente * resistencia

Resistencia = voltaje/corriente

Resistencia = 3.5/0.28

Resistencia = 12.5 Ohmios

Por tanto, la resistencia del filamento de una linterna de bolsillo es de 12,5 ohmios.

In this experiment, time represents the variable that is independent and graphed on the horizontal axis.

The period of the pendulum does not depend on the mass of the sphere, only on the length of the chord. Two pendulums with different masses but the same length have the same period. Two pendulums of different lengths have different periods with the pendulum with the longer string having a longer period.

For small deflections of less than 15 degrees, the pendulum experiences simple harmonic oscillations. This means that its restoring force is directly proportional to its deflection. A simple pendulum is called a simple pendulum. The longer the pendulum is, the longer it will take to travel the distance it swings from side to side. The period of a pendulum is the time it takes for the weight to swing and return to its original position so it means a longer period.

The spectrum observed from the Sun (or any star) would exhibit an absorption spectrum. This is because the outer gaseous atmosphere of the star absorbs specific wavelengths of light, resulting in dark absorption lines in the spectrum.

In the cooler, lower-density outer atmosphere, where white light from the star travels, some atoms or molecules in the atmosphere absorb photons with particular energy. In the spectrum, these absorptions show up as black lines at specific wavelengths. The specific set of absorption lines that each element or molecule generates results in a distinctive pattern that can be used to identify the elements that are present in the star's atmosphere.

The absorption spectrum offers insightful data on the chemical make-up and physical characteristics of the star. Astronomers can ascertain the elements present, their abundances, and other characteristics like the temperature, pressure, and velocity of the star's atmosphere by examining the absorption lines.

Before moving away from the right curb to enter traffic, it is essential to perform several important checks to ensure a safe maneuver.

First, ensure that your vehicle is properly positioned close to the right curb, allowing enough space for traffic to pass on your left. Adjust your side and rearview mirrors to provide maximum visibility.

Once your vehicle is properly positioned, activate your turn signal to indicate your intention to merge into traffic. Check your rearview mirror to assess the speed and distance of approaching vehicles. Then, glance over your left shoulder to check your blind spot, an area that may not be visible in your mirrors.

This last shoulder check is critical as it helps you identify any vehicles, cyclists, or pedestrians that may be approaching from behind and could potentially be in your path as you move away from the curb. By performing this check, you can ensure that there are no hidden hazards and that it is safe to merge into the traffic lane.

Remember, maintaining awareness of your surroundings and performing the necessary checks before entering traffic is vital for a safe and successful merge.

The velocity of the ion released from rest and accelerated through a potential difference of 152V is 6.34 × 10^5m/s.

The electric potential difference is a scalar quantity that measures the energy required per unit of electric charge to transfer the charge from one point to another. The electric potential difference between two points in an electric circuit determines the direction and magnitude of the electric current that flows between those two points. A lithium-ion containing three protons and four neutrons has a mass of 1.16 × 10-26 kg. The ion is released from rest and accelerates as it moves through a potential difference of 152 V.

The change in electric potential energy of an object is equal to the product of the charge and the potential difference across two points. The formula to calculate the velocity of the ion released from rest and accelerated through a potential difference of 152V is:

v = √(2qV/m) where q is the charge of the ion, V is the potential difference, and m is the mass of the ion.

Substituting the values in the formula, we get:

v = √(2 × 1.6 × 10-19 C × 152 V/1.16 × 10-26 kg)v = 6.34 × 10^5m/s

Therefore, the velocity of the ion released from rest and accelerated through a potential difference of 152V is 6.34 × 10^5m/s.

When the earth wire is connected to the metal case of the washing machine, it provides an alternative pathway for electric current to flow if there is a fault, such as if the live wire touches the metal case. The earth wire is connected to the ground, which has zero potential, so any current that flows through the earth wire will not harm a person who touches the metal case. This is because the person's body is also at zero potential (ground potential) and there will be no potential difference (voltage) across the person's body, which means no electric current will flow through the person's body. Therefore, connecting the earth wire to the metal case of the washing machine ensures that any electrical faults will be safely conducted away from the person, reducing the risk of electric shock or electrocution.

The total mass of blood in the average human is approximately 5.3 kilograms.

To find the total mass of blood in the average human, we need to multiply the volume of blood by its density.

Given that the average human body contains approximately 5 liters of blood and the density of blood is 1060 kg/m^3, we can proceed as follows:

1. Convert 5 liters to cubic meters:
1 liter = 1/1000 cubic meters
So, 5 liters = 5/1000 = 0.005 cubic meters

2. Multiply the volume of blood by its density:
Mass = Volume × Density
Mass = 0.005 cubic meters × 1060 kg/m^3

3. Calculate the total mass of blood:
Mass = 5.3 kg

Therefore, the total mass of blood in the average human is approximately 5.3 kilograms.
