Bridget is in science class. her teacher gives her two unknown substances and asks her to determine their relative ph. she places a piece of red litmus paper into both substances. the litmus paper turns purple when she places it into substance i. the litmus paper turns blue when she places it into substance ii.
Answer:
Explanation:
Litmus paper is often used to determine the range of pH of an aqueous solution. Litmus paper specifically contains 10-15 natural dyes, in the presence of acidic solution it turns red, it turns purple when the solution is neutral and blue when dealing with basic solutions. Red litmus paper stays red for a neutral and acidic solution but changes to blue in the presence of alkaline solutions. On the other hand, blue litmus paper turns red when a solution is acidic but stays blue for neutral and alkaline solutions. Since the paper turns purple in the presence of solution 1 we know that is neutral, meanwhile, since it turns blue for the second solution we know that solution II is a base correct answer is Substance I is a neutral substance and substance II is a base.

Answer:
Answer 1) Decomposing (Electrolysis) Answer 2) Solar energy
Explanation:
Answer 1) Decomposing (Electrolysis)
Explanation :
Hydrogen can be created by decomposing water. Electrolysis which is a method of passing electricity from the water and obtaining the products as hydrogen and oxygen is done by decomposition of water. The water molecule is broken down into its constituents.
Answer 2) Solar energy
Explanation :
If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is Solar energy.
Solar energy from the sun can be used to lower the energy of activation during the decomposition of water. Solar energy is a renewable energy source as it comes from the sun and is replenish-able unlike fuels which cannot be replenished. The solar energy can be collected and utilized for production of hydrogen.

Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m. which group describes 16% of the oarfish population? select each correct answer.
Answer:
Explanation:
oarfish that are shorter than 5 m
Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99
This indicates that the sample mean is lower than the population mean
Therefore,
- 0.99 = (x - 6.5)/1.5
- 0.99 × 1.5 = x - 6.5
- 1.5 = x - 6.5
x = - 1.5 + 6.5
x = 5m
The correct answer is
oarfish that are shorter than 5 m

A container with a fixed volume filled with hydrogen gas
Based on the calculations, the new temperature of this hydrogen gas at a fixed volume is equal to 258.72°C.
How to determine the new temperature?In order to calculate the new temperature of this hydrogen gas at a fixed volume, we would apply Gay Lussac's law.
Mathematically, Gay Lussac's law is given by this formula;
P α T
P = kT
Where:
P is the pressure.T is the temperature.k is the constant of proportionality.Given the following data:
Initial temperature = -104°C to K = 273 - 104 = 169 K.Final pressure = 71.8 kPa.Initial pressure = 225.9 kPa.Substituting the given parameters into the formula, we have;
[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2} \\\\\frac{71.8}{169} =\frac{225.9}{T_2} \\\\71.8T_2 =38177.1\\\\T_2 = 38177.1/71.8[/tex]
T₂ = 372.5/0.96
New temperature = 531.72 K.

Of the 318 sophomores, 140 are taking algebra 2 and 102 are taking chemistry. of those that are taking chemistry, 76 are not taking algebra 2. if a sophomore is chosen at random, find the probability that they are taking algebra 2, if it is known that they take chemistry.
The probability that the sophomores are taking algebra 2 is equal to 0.63.
How to find the probability?In order to determine the probability that the sophomores are taking algebra 2, we would calculate the number of sophomores that takes algebra 2 but not chemistry and those that do not take chemistry.
For algebra 2 but not chemistry, we have:
Algebra 2 but not chemistry = 140 - 76
Algebra 2 but not chemistry = 64.
For those not taking chemistry, we have:
Not taking chemistry = 318 - 102
Not taking chemistry = 216.
Now, we can find the probability that the sophomores are taking algebra 2:
P(A) = 64/102
P(A) = 32/51
P(A) = 0.63.

The cross-sectional areas of a triangular prism and a right cylinder are congruent. the triangular prism has a height of 10 units, and the right cylinder has a height of 7 units. which conclusion can be made from the given information? the volume of the prism is half the volume of the cylinder. the volume of the prism is not equal to the volume of the cylinder. the volume of the prism is twice the volume of the cylinder. the volume of the prism is equal to the volume of the cylinder.
The volume of the right-angle prism and the right-cylinder shapes is not equal. Thus, option A is correct.
What is Volume?Volume is given as the scalar quantity that can measure the space occupied by a three-dimensional object.
The volume of the prism is given as:
Volume of prism = Area * Height
The volume of right cylinder is given as:
Volume of cylinder = Area * Height
The given two shapes are congruent to each other, thereby the area of the base of the prism and cylinder are equal. Substituting the height of both the shapes:
The volume of Prism = 10 Area
Volume of right cylinder = 7 Area
The ratio of the volume of both shapes gives:
Volume of Prism/ Volume of Cylinder = 10 Area/ 7 Area
Volume of Prism/ Volume of Cylinder = 1.42
Volume of Prism = 1.42 Volume of Cylinder
Thus, the volume of Prism is 1.42 times more than the volume of a cylinder. Hence, the volume of both shapes is not equal. Thus, option A is correct.

Research the use in the military of magnetic anomaly detectors, mads. write a brief 300-word essay answer the following questions on mads. what is the main idea behind mads? what can be detected by using mads? a brief history of the mad development.
Answer:
MADs are Magnetic Anomaly Detectors and the main idea behind MADs is that they follow the principle rule that objects with metallic properties get in the way of the magnetic lines of the Earth's forces. Metallic things such as submarines are normally detected using MADs. MAD development started around 1917. The function of the MADs was to identify anomalies in the Earth’s magnetic field that were caused by submarines. Later on, around 1941 in the US and Britain, there was a development of magnetic detection devices. These were meant to measure Earth’s magnetic field. So ultimately after this in 1943, MADs were now installed in ASW aircrafts. However, due to its limited range and its incapacity to detect the magnetic variances of different sources, MADs started to be used along with sonobuoys which was the opposite of what they were intended to be used for.
Explanation:
The primary concept underlying MADs, which stand for Magnetic Anomaly Detectors, is that they adhere to the general notion that things with metallic qualities obstruct the magnetic lines of the Earth's forces.
What is Magnetic Development?MADs are used to find metallic objects, like submarines. Around 1917, MAD development first began.
The purpose of the MADs was to locate submarine-related magnetic anomalies in the Earth's magnetic field. Later, about 1941, magnetic detecting technology developed in the US and Great Britain.
These were designed to gauge the magnetic field of the planet. As a result, MADs were eventually deployed in ASW aircraft in 1943. However, MADs have a restricted range and are unable to detect the magnetic variations of many sources.
Therefore, The primary concept underlying MADs, which stand for Magnetic Anomaly Detectors, is that they adhere to the general notion that things with metallic qualities obstruct the magnetic lines of the Earth's forces.
