state two things are necessary for a rainbow to form
Answers
Answer:
Sunlight (The sun should be behind us)
Water droplets (Raindrops)
How is a rainbow formed?Rainbows are an optical phenomenon caused by light refracting through airborne water droplets. The angle between you, the water droplet, and the sun determines the apparent color of the water droplets. Rainbows appear to float in the sky and move as you walk. The sky is serving as a screen for an optical illusion.
The most important thing to understand about rainbows is that they are not an item or region "out there," and hence rainbows do not have a location (which is why you can never reach the end when walking toward them). They are also not arc-shaped, but rather round.
When the air is misty, each water droplet functions like a little prism, refracting light from a single point source (the sun) and dispersing colored light (unmixed single-frequency light) in all directions. The rainbow optical illusion is caused by millions of water droplets taking on a certain hue from a specific point of view. Water droplets that give color to your eyes are those that are at a specific geometric angle in space related to the sun and your specific position. They are usually far away, with the sun behind you.
A rainbow would create a complete circle if not for the earth, which cuts the circle into a half-arc. Rainbows seem to be a full circle when viewed through airplane windows.
Light from the sun behind you enters a distant water droplet, refracts at the spherical surface of the drop, reflects off the rear of the drop, and then heads your way. The refraction process divides the light so that just a small color band penetrates your eye, imparting a luminous color to the drop.
The second rainbow of a double rainbow reflects twice within the drop before reaching you, which is why it is weaker (light is lost on each reflection) and reversed in hue (the second reflection makes the color order a mirror image).

Which auxilliary label should be placed on the container?A Protect from lightB Take with a full glass of waterC Caution: flammable substancesD Shake well before usingE May discolor the urine
Answers
"Protect from light," is the correct auxiliary label that should be placed on the container.
Tetracycline hydrochloride is an antibiotic used to treat a variety of bacterial infections. However, tetracycline is susceptible to photolysis, which means that it can break down when exposed to light. This can reduce the effectiveness of the medication.
In the context of the statement, a pharmacist has prepared a tetracycline hydrochloride 2.2 mg/mL topical solution. Since tetracycline is susceptible to photolysis, an auxiliary label should be placed on the container to remind patients and healthcare providers to protect the medication from light.
Option A, "Protect from light," is the correct auxiliary label that should be placed on the container. This label will remind patients and healthcare providers that tetracycline hydrochloride is susceptible to photolysis and should be protected from light. This will help to ensure that the medication remains effective and provides the intended treatment for the bacterial infection.
Option B, "Take with a full glass of water," is not relevant in this context since it does not address the issue of tetracycline's susceptibility to photolysis. Option C, "Caution: flammable substances," is also not relevant since tetracycline hydrochloride is not a flammable substance. Option D, "Shake well before using," is also not relevant in this context since the statement refers to a topical solution, not an oral medication. Option E, "May discolor the urine," is also not relevant in this context since it does not address the issue of tetracycline's susceptibility to photolysis.
In conclusion, the correct auxiliary label that should be placed on a container of tetracycline hydrochloride 2.2 mg/mL topical solution is "Protect from light." This will help to ensure that the medication remains effective and provides the intended treatment for the bacterial infection by avoiding photolysis.

Two sources of light of wavelength 700 nm are 12 m away from a pinhole of diameter 0.7 mm. How far apart must the sources be for their diffraction patterns to be resolved by Rayleigh's criterion
Answers
The sources must be 0.042 meters (42 mm) apart for their diffraction patterns to be resolved by Rayleigh's criterion.
To find the distance between the sources, we can use Rayleigh's criterion formula:
θ = 1.22 * (λ / D)
where θ is the angular separation, λ is the wavelength, and D is the diameter of the pinhole. First, calculate the angular separation:
θ = 1.22 * (700 nm / 0.7 mm) = 1.22 * (700 * 10^(-9) m / 0.7 * 10^(-3) m) ≈ 1.22 * 0.001 = 0.00122 radians
Next, we can use the formula for angular separation to find the distance between the sources:
distance = θ * L
where L is the distance from the pinhole to the sources (12 m in this case). So,
distance = 0.00122 radians * 12 m ≈ 0.042 meters (42 mm)
Summary: For the two sources of light with a wavelength of 700 nm and 12 m away from a pinhole of diameter 0.7 mm, they must be 0.042 meters (42 mm) apart for their diffraction patterns to be resolved by Rayleigh's criterion.

Reflecting telescopes use mirrors to bring light to a focus. All large telescopes are reflectors because_____
Answers
All large telescopes are reflectors since they offer these benefits and are better suited for large telescopes.
Specifically: It is feasible to manufacture telescopes with wider apertures (larger diameter mirrors), which can collect more light and provide higher resolution images, because mirrors can be produced larger than lenses without sagging under their own weight.
Thin metal sheets can be applied to mirrors to improve reflectivity and decrease light loss.
Mirrors can be supported from the back, which increases their rigidity and solves the lens flexure issues that plague refracting telescopes.
Although producing huge lenses to exact specs is more expensive and complex than producing large mirrors, reflectors are typically less expensive to produce than refractors.

determine the magnitude and direction of the force between two parallel wires 35 m long and 4.0 cm apart, each carrying 35 a in the same direction.
Answers
The magnitude of the force between the two parallel wires can be calculated using the formula:
F = μ0 * I1 * I2 * L / (2πd)
Where F is the force, μ0 is the permeability of free space (4π x 10^-7 Tm/A), I1 and I2 are the currents in the two wires, L is the length of the wires, and d is the distance between the wires.
Plugging in the given values, we get:
F = (4π x 10^-7 Tm/A) * 35 A * 35 A * 35 m / (2π * 0.04 m)
F = 0.61 N
The direction of the force can be determined using the right-hand rule. If the current in the first wire is flowing from south to north, and the current in the second wire is also flowing from south to north, then the force between the wires will be attractive, and will act towards the center of the wires.
The force between two parallel wires carrying current is due to the interaction of the magnetic fields produced by the currents. The magnetic field around a current-carrying wire is circular, and the direction of the field depends on the direction of the current. When two wires are placed parallel to each other, the magnetic fields around them interact and produce a force between the wires.
The force is proportional to the currents in the wires, the length of the wires, and inversely proportional to the distance between the wires. The direction of the force can be determined using the right-hand rule, which states that if the thumb of the right hand points in the direction of the current in the first wire, and the fingers point in the direction of the current in the second wire, then the palm of the hand will indicate the direction of the force. If the force is attractive, it will act towards the center of the wires, and if it is repulsive, it will act away from the center.

Answers
If the current through the resistor is 2.80 A the terminal voltage of the battery is 23.2 V.
We can use Ohm's law to find the voltage drop across the resistor:
V = IR
Where V is the voltage drop, I is the current through the resistor, and R is the resistance.
Substituting the given values, we get:
\(V = (2.80)*(4.00) = 11.2 V\)
This is the voltage drop across the resistor. The voltage across the battery terminals will be higher than this by the amount of the battery's internal resistance, which we can assume to be negligible. Therefore, the terminal voltage of the battery is:
\(V_{Ter} = V + V_r\)
Where \(V_r\) is the voltage drop across the resistor.
\(V_{Ter}= 11.2 V + 12.0 V = 23.2 V\).

The temperature of the chemical product at the outlet of the reactor is 120°C and the length of the pipe connecting between the reactor and the storage tank is 3 meters. The convective coefficient of the chemical product flowing inside the internal surface of the pipe is estimated as h = 4000 W/m² °C. The entire pipe is exposed to a free convection surrounding condition with h = 6.5 W/m² °C and temperature of 30°C. As a process engineer, you have noticed that there was a huge temperature drop between the adiabatic reactor and the storage tank due to the heat loss during the transfer process. You have been assigned to insulate the outer surface of the steel pipe. iv) If the entire insulated pipe as calculated above is exposed to a forced convection surrounding condition with h = 30 W/m².°C and temperature of 30 °C, estimate the total heat loss under this condition. Compare and evaluate the heat loss under the free and forced convection conditions. In your opinion, which type of convection do you prefer for this problem? Provide your reasons.
Answers
The total heat loss under the given condition is 599.21 W. The heat loss is higher under free convection surrounding conditions as compared to forced convection surrounding conditions. Forced convection should be preferred for this problem as it helps to minimize heat loss.
Given: Length of the pipe, L = 3 m
Thermal conductivity, k = 43 W/m°C
Convective coefficient, h1 = 4000 W/m²°C
Convective coefficient of free convection, h2 = 6.5 W/m²°C
Convective coefficient of forced convection, h3 = 30 W/m²°C
The outlet temperature of a chemical product, T1 = 120°C
External temperature, T2 = 30°C
Under steady-state conditions, the rate of heat loss through the insulated pipe under free convection can be expressed as:
Q = (T1 - T2)/{[1/(h1 . D)] + [(ln(ro/ri))/(2π k L)] + [1/(h2 . D)]}
Here, D is the diameter of the pipe, ro, and ri are the outer and inner radius of the pipe, respectively.
The outer radius of the insulated pipe is given as:
ro = ri + 2 × insulation thickness
= 1.25 + 2 × 0.05= 1.35 mri
= 1.25 m
D = 2.5/1000 = 0.0025 m
Substitute the given values to find the heat loss:
Q1 = (120 - 30)/{[1/(4000 × 0.0025)] + [(ln(1.35/1.25))/(2π × 43 × 3)] + [1/(6.5 × 0.0025)]}
= 1.1204 WK
Under forced convection, the rate of heat loss through the insulated pipe can be expressed as:
Q = (T1 - T2)/{[1/(h1 . D)] + [(ln(ro/ri))/(2π k L)] + [1/(h3 . D)]}
Substitute the given values to find the heat loss:
Q2 = (120 - 30)/{[1/(4000 × 0.0025)] + [(ln(1.35/1.25))/(2π × 43 × 3)] + [1/(30 × 0.0025)]}= 0.5212 WK
So, the total heat loss under forced convection is lower than the free convection, and hence, it should be preferred.
