At the beach in San Francisco (0 meters) the pressure of the atmosphere is 101.325 kPa
Korvikt [17]

Answer:

P = -\frac{17978}{1609344}(h)+101.325

Explanation:

Given

h = height

P = Pressure

(h_1,P_1) = (0,101.325)

(h_2,P_2) = (1609.344 ,83.437 )

Required

Determine the linear equation for P in terms of h

First, we calculate the slope/rate (m);

The following formula is used:

m = \frac{P_2 - P_1}{h_2 - h_1}

Substitute values for P's and h's

m = \frac{83.347 - 101.325}{1609.344- 0}

m = \frac{-17.978}{1609.344}

m = -\frac{17.978}{1609.344}

Multiply by 1000/1000

m = -\frac{17.978 * 1000}{1609.344*1000}

m = -\frac{17978}{1609344}

The equation is then calculated using:

P - P_1 = m(h - h_1)

Substitute values for m, h1 and P1

P - P_1 = m(h - h_1)

P - 101.325 = -\frac{17978}{1609344}(h - 0)

P - 101.325 = -\frac{17978}{1609344}(h)

Make P the subject

P = -\frac{17978}{1609344}(h)+101.325

<em>The above is the required linear equation</em>

Julia margaret cameron used a short focal length lens that allowed only a small area of sharp focus. what kind of effect would a
Klio2033 [76]

Julia margaret cameron used a short focal length lens that allowed only a small area of sharp focus. The effect that the lens like this produce would be Less Magnification and Wide Angle of view.

A lens having short focal length will produce Less Magnification and Wide Angle of view.

Short focal length gives a deeper depth of the present field in addition to the wide angle of view. They capture maximally that lies in their front of the camera to the infinity.

A lens with large focal length captures a narrow field band as compared to the one with short focal length.

The lower focal length shows the short depth of focus leading to less magnification.

Short focal length is determined by the radius of curvature of both the curvature of the lens, the medium of the surrounding and the refractive index of the lens given.

Focal length of camera shows how much band the camera is able to capture.

How does a pedometer help people reach their fitness goals?
Greeley [361]

Answer:

Pedometers are designed to detect vertical movement at the hip and so measure the number of steps and provide an estimate of distance walked. They cannot provide information on the temporal pattern of physical activity or the time spent in different activity at different intensity.
