In Figure 20.15, a rectangular current loop is carrying current I1 = 7.0 A, in the direction indicated near a long wire carrying a current Iw. The long wire is parallel to the sides of the rectangle. The rectangle loop has length 0.80 m and its sides are 0.10 m and 0.70 m from the wire. If the net force on the loop is to have magnitude 1.7x10^-6 and is to be directed towards the wire, what must be the (a) magnitude and (b) direction (from top to bottom or from bottom to top in the sketch) of the current Iw in the wire?

Note that:

\(\mu_{0}=4 \pi \times 10^{-7} \mathrm{~T} \cdot \mathrm{m} / \mathrm{A} .\)

The results of a study showed that heterosexual? women, during? ovulation, were significantly better at correctly identifying the marriage status of a man from a photograph of his face than women who were not ovulating. Near? ovulation, on average women correctly identified the marriage status of about 69?% of the 100 men shown to them. Assume that the sample distribution for this study is unimodal and symmetric and that the samples are collected randomly. If this is the probability of correctly identifying the marriage status of a man in any given? photograph, what is the probability a woman would correctly classify 78 or more of the? men?

The probability is ( ) ?

(Round to five decimal places as? needed.)

Explain steps please

What determines how well a regression equation will predict values of the y-variable from known values of the x-variable? (A) What values or points make-up the regression line? (B) What two points are always found on the regression line? (Hint: These two points can be used to quickly draw the regression line) Explain why the regression line the “best fitting” line that can be plotted through the points in a scatter diagram? Describe how predicted y-values plotted near the point of averages differ in their accuracy compared to predicted y-values plotted further away from the point of averages.

Wilson is a 36-year-old migrant worker. He was admitted to the Hospital with a cough, unintended weight loss, and night sweats. He is staying with 6 friends in a one bedroom apartment near the strawberry field where he works. The ED physician suspects Tuberculosis (TB).

What diagnostic testing will the Provider order to confirm a diagnosis of TB?

What Isolation precautions do you expect to be put in place and why?

Describe the recommended treatment regimen for TB, including the rationale for combination drug therapy.

Identify the reason compliance to medication therapy is often a concern in the patient with TB.

What should be done for Wilson's 6 roommates?

Suppose we perform a double-slit experiment with a detector placed at a position of minimum intensity (maximum destructive interference), off-center where the path lengths differ by half a wavelength. The light source is alternately turned on and off (or blocked and unblocked near the source) and the intensity over time is recorded. I interpret the uncertainty principle to mean that there will be a peak in intensity at the times when the switch is flipped (whether on-to-off or off-to-on). i.e., it will look something like this (in ASCII art):

Is this correct? I have had trouble convincingly explaining my reasons for thinking so. What will be the measured intensity over time and why?

This question was from a test and we cannot figure out how to get the correct answer. We already have the concentration and can in theory get to ppm by getting to 10^-6 rather than -4 given, but how does it change from 3.14 to 375 of some decimal combination. Can someone please explain step by step?

The mole fraction of carbon dioxide in dry air near sea level is 3.14×10⁻⁴ where the molar mass of carbon dioxide is 44.010. The concentration of carbon dioxide in the atmosphere is __________ ppm.

A farsighted woman breaks her current eyeglasses and is using an old pair whose refractive power is +5/3 diopters. Since these eyeglasses do not completely correct her vision, she must hold a newspaper 42.00 cm from her eyes in order to read it. She wears the eyeglasses 2.00 cm from her eyes.

a.      What is the focal length of the lenses?

b.      Are the lenses converging or diverging? Why?

c.       How far is her near point from her eyes?

D. In order to be able to read the newspaper at 25cm from her eyes, what must her new prescription (diopters) be?
