Answer: D)The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut.

Explanation:

The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut. Gravity is a very weak force and varies with mass and the inverse square of distance. The astronaut's distance from Earth and the relative small mass of ISS result in gravitational force near zero.

Calculate the number of moles of solute present in 185.0 mL of a 1.50 mol/L solution of HCl.
____ [38]

Answer:

0.278 mol HCl

Explanation:

We currently have 185.0 mL of a 1.50 mol/L solution of HCl. We want to find the number of moles there are.

Based on the given information, our volume is 185.0 mL and our molarity is 1.50. Because molarity is defined as moles / Litre, we can easily find the moles given volume by multiplying molarity by volume.

First, though, we must convert millilitres to litres. There are 1000 mL in 1 L, so divide 185.0 by 1000:

185.0 / 1000 = 0.185 L

Now, multiply 0.185  by 1.50:

0.185 L * 1.50 mol/L = 0.278 mol HCl

Thus the answer is 0.278 mol HCl.

Which scatterplot shows the correct division for using the Divide-Center of Data method to draw the trend line?
nlexa [21]

The appropriate scatter plot that depicts the correct division for using Divide center to draw trend line is the plot D.

<h3>What are Scatter plots?</h3>

Scatter plots are used to show how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the position of which is determined by the values of the columns set on the X and Y axes. Scatter plots are graphs that show the relationship of two variables in a data set. It is a two-dimensional plane or a Cartesian system that represents data points.

In order to draw a trend line correctly, divide the points using the divide center method. The dividing vertical line must be drawn at the midpoint (a position where the number of data points to the left and right of the vertical line is equal).

Only option D has a vertical line dividing the 6 data points into two equal portions when the options are evaluated based on this condition.

The diagram is attached.
