OA is B -The figure shows a normal distribution with mean m and standard deviation d, including approximate percents of the distribution in each of the six regions shown. For a population of 800,000 subway riders, the numbers of subway trips taken per rider last January are approximately normally distributed with a mean of 56 trips and a standard deviation of 13 trips. Approximately how many of the riders took between 30 and 43 trips last January?

The surface tension of water in air is approximately 0.00518 lbf/ft. if the atmospheric pressure is 14.7psia, what is the pressu
strojnjashka [21]

Based on the calculations, the pressure inside this droplet is equal to 2,909.35 kPa.

<u>Given the following data:</u>

  • Surface tension = 0.00518 lbf/ft to N/m = 0.00702 N/m.
  • Atmospheric pressure = 14.7psia to kPa = 101.35 kPa.
  • Diameter = 0.01 mm to m = 0.00001 m.

Radius, r = \frac{diamter}{2} =\frac{0.0001}{2} = 0.000005 m.

<h3>How to determine the pressure inside a droplet.</h3>

For a droplet with only one surface, its pressure is given by this formula:

P_1-P_2=\frac{2 \tau}{r} \\\\P_1=\frac{2 \tau}{r}+P_2

Substituting the given parameters into the formula, we have;

P_1=\frac{2 \times 0.00702}{0.000005} + 101.35\\\\P_1=2808+ 101.35

Inside pressure = 2,909.35 kPa.

Distinguish between catabolism and anabolism giving an example of each
Alex
Catabolism is what happens when you digest food and the molecules break down in the body for use as energy. Large, complex molecules in the body are broken down into smaller, simple ones.

What is the initial direction of deflection for the charged particle entering the magnetic field shown in (Figure 1) (a) ?
lesya692 [45]

If the current is pointing into the page, the direction of the magnetic field will be upwards.

<h3>What is direction of magnetic field?</h3>

The Maxwell right-hand thumb rule is used to indicate the direction of the magnetic field in the direction of the current or charge.

According to this rule, "if the thumb of the right-hand points along the direction of the current, then the remaining curled fingers of the same hand give the magnetic field direction due to the current".

Thus, when the current is pointing into the page, the direction of the magnetic field will be upwards.
