The movie 'Contagion' features a virus called MEV-1 that spreads based on factors like nutrition, underlying conditions, socioeconomic factors, and clean drinking water. Dr. Cheever's statement about these factors' influence on disease spread is valid, and the irony lies in the fact that shaking hands, once a symbol of trust, can actually spread diseases.
1. The pathogenic agent in the movie 'Contagion' was a virus called MEV-1.
2. Dr. Ellis Cheever's statement about the spread of the disease is valid. Nutrition, underlying conditions, socioeconomic factors, and access to clean drinking water can all affect a person's immune system and ability to fight off infections.
3. The irony in Dr. Cheever's statement is that shaking hands, which was once seen as a sign of trust and nonviolence, can actually spread diseases like the one depicted in the movie.

Answer:
Independent Variable = Years
Dependent Variable = Number of Mobiles phone owners
Explanation:
Independent variables are plotted on x-axis and the dependent variables are plotted on y-axis.
In given graph the "Years" belong to x-axis hence, years are the independent variables.
Also, "Number of Mobile phones owners" belong to y-axis hence, this number is the dependent variable.

Introduction:
Understanding the amount of energy required to change the temperature of a substance is fundamental in many fields, from chemistry and physics to engineering and everyday applications. In this case, we're looking at how much energy it takes to heat a 75 g sample of aluminum.
Specific Heat Capacity of Aluminum:
To determine the energy required, we first need to consider the specific heat capacity of aluminum. The specific heat capacity (c) is a unique property of each material and represents the amount of heat energy needed to raise the temperature of 1 gram of that substance by 1 degree Celsius (or 1 Kelvin). For aluminum, the specific heat capacity (c) is approximately 0.897 J/g°C (joules per gram per degree Celsius).
Mass of the Sample:
The next piece of the puzzle is the mass of the aluminum sample. You mentioned that it's 75 grams, so we'll use that value in our calculations.
Change in Temperature:
We're looking to raise the temperature of the aluminum from 22.4°C to 94.6°C. To find the change in temperature (ΔT), we subtract the initial temperature from the final temperature:
ΔT = 94.6°C - 22.4°C = 72.2°C
Calculating the Energy:
Now, we can use the specific heat capacity formula to calculate the energy (Q) needed to raise the temperature of the aluminum sample:
Q = m * c * ΔT
Where:
Q is the energy in joules (J).
m is the mass of the sample (75 g).
c is the specific heat capacity of aluminum (0.897 J/g°C).
ΔT is the change in temperature (72.2°C).
Plugging in these values:
Q = 75 g * 0.897 J/g°C * 72.2°C
Q ≈ 4863.15 J
Conclusion:
Therefore, approximately 4863.15 joules of energy are needed to raise the temperature of a 75 g sample of aluminum from 22.4°C to 94.6°C. This calculation is essential in various scientific and practical applications, from cooking to materials engineering, and helps us understand the energy requirements for temperature changes in different substances.

An atom is electrically neutral when it has an equivalent number of protons and electrons. Therefore, an atom with 35 protons in the nucleus will also have 35 electrons orbiting the nucleus.
In atomic theory, an atom is neutral when the number of protons present in the nucleus is equal to the number of electrons orbiting the nucleus. For example, hydrogen atoms all have one proton in the nucleus and one electron orbiting the nucleus. Therefore, if an atom has 35 protons in the nucleus, it will also have 35 electrons orbiting the nucleus. This is due to the characteristic of atomic structure that aims for neutrality by maintaining an equal number of positive protons and negative electrons.
