Natasha and Reanna observe a large airplane in the troposphere. Which experimental setup below would best determine how changing wind speeds might affect the airplane’s flight time to its destination?
The airplane's flight time is the test variable (independent variable), the wind speed is the outcome variable (dependent variable), and the airplane is the constant.
The airplane's flight time is the outcome variable (dependent variable), the wind speed is the test variable (independent variable), and the airplane is the constant.
The airplane's flight time is the constant, the wind speed is the outcome variable (dependent variable), and the airplane is the test variable (independent variable).
The airplane's flight time is the test variable (independent variable), the airplane is the outcome variable (dependent variable), and the wind speed is the constant.
Answer:
i am pretty sure the answer is a
Explanation: because the airplane's flight time has to be the independent variable for it to affect the dependent variable that is the speed of how fast the airplane is going.
Independent variables are test variables where we are testing its effects on the dependant variables. Here wind speed is the independent variable and time of flight is dependant variable.
What are variables?Variables are values or components in an experiment which can be measured and will change by time. In an experiment there are two kinds of variables namely independant and dependant variables.
Dependant variables are those which changes with effect of independent variables. For example if we are studying the effect of water quality in the population of fish in a pond. The independent variable is the quality of water and fish population is the dependent variable.
Here the time of flight depends on the wind speed. Thus, flight time is the dependant variable and wind speed is the test variable or independent variable.

If body fat has a density of .94g/mL and 4.0L of fat is removed, how many pounds of fat were removed?
Answer:
8.3lb of fat were removed
Explanation:
To solve this problem we need to convert the liters of fat removed to mL. Using the mL and density we can find the grams. To convert grams to pounds we must use (1lb = 453.592g):
mL fat:
4.0L * (1000mL / 1L) = 4000mL
g fat:
4000mL * (0.94g / mL) = 3760g of fat
lb fat:
3760g of fat * (1lb / 453.592g) =

3.A sample of chlorine contains 75% of 35
17Cl and 25% of 37
17Cl.
Calculate the relative molecular mass of chlorine.
Answer:
35.5
Explanation:
Given parameters:
Abundance of chlorine Cl - 35 = 75%
Mass of Cl - 35 = 35
Abundance of Cl - 37 = 25%
Mass of Cl - 37 = 37
Unknown:
Relative molecular mass = ?
Solution:
The relative molecular mass of the chlorine can be deduced using the expression below:
Relative molecular mass = (abundance x mass of Cl - 35) + ( abundance x mass of Cl - 37)
Relative molecular mass = (75% x 35) + (25% x 37) = 35.5

B.
A skin cell provides protection, but skin tissue does not.
C.
A skin cell grows more than skin tissue grows.
D.
A skin cell contains fluid, but skin tissue does not.
Answer:
A. A skin cell has a less complex structure than skin tissue has.
Explanation:
A skin cell has a less complex structure than skin tissue has. Hence option A is correct.
What is cell?Cell is defined as the smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The three essential parts of a cell are the cell membrane, nucleus, and cytoplasm. From bacteria to humans, cells give all living things their structure and functionality.
The tiniest, structurally and functionally distinct, and typically microscopic, unit of an organism is called a cell. The several forms of material made up of specialized cells and their byproducts are referred to as tissues. Cells are very small. The size of tissues is macro.
Thus, a skin cell has a less complex structure than skin tissue has. Hence option A is correct.

What frequency is radiation with a wavelength of 5.00 x 10^-6 cm? In what region of the electromagnetic spectrum is this radiation?
P.S it's due today
Answer:
f = 6 × 10^15 Hz in the ULTRAVIOLET (UV) region
Explanation:
Using λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
According to this question, λ = 5.00 x 10^-6 cm
= 5.00 x 10^-8 m
λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 5.00 x 10^-8
f = 0.6 × 10^(8+8)
f = 0.6 × 10^16
f = 6 × 10^15 Hz
In the electromagnetic spectrum (EM), a frequency of 10^15 is found in the ULTRAVIOLET region. This means that this radiation with a wavelength of 5.00 x 10^-6 cm and frequency of 6 × 10^15 Hz is in the ULTRAVIOLET region of the EM spectrum.

What does the calculated value of the equilibrium constant, Keq indicate regarding the degree of completeness of the reaction? In other words, at equilibrium, are there mostly products, reactants, or relatively large amounts of both?
Answer:
both
Explanation:
because equilibrium means that both sides of the reaction are equal
The concentration of the products is high at equilibrium if Keq is a large number (Keq > 1). The reaction in this instance encourages the production of products. The concentration of the reactants is high at equilibrium if Keq is a small number (Keq1).
What is equilibrium ?Chemical equilibrium is the condition where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties.
The size of a reaction when it is at equilibrium is represented by the equilibrium constant, K. It creates a ratio using the concentrations and coefficients of each reactant and product.
K is regarded as intermediate if it is larger than or equal to 0.001 but less than or equal to 1000. Significant quantities of reactants and products will be present. When the equilibrium constant K is big, products predominate at equilibrium, but when it is small, reactants predominate.
Thus, The concentration of the products is high at equilibrium if Keq is a large number.
