Answer:

Answer:

Opaque object

Explanation:

Shadow forms when an opaque object comes in the way of light. Because opaque objects does not allow light to pass through them and light travels in a straight line. Hence a retreating figure of the same opaque object ,forms and it's black in colour without any detail just outline.

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>

Misha Larkins [42]

Complete Question:

Which technology is set up on the marketing team's phones?

a) Bluetooth

b) Tethering

c) NFC

d) Hotspot

Answer:

NFC

Explanation:

Near Field Communication (NFC) is a short-range wireless connectivity standard that uses magnetic field induction to enable communication between devices when  brought within a few centimetres from each other. NFC offers a secured communication between connected electronic devices with simple setup that can be used to bootstrap more-capable wireless connections. It only covers a range of 10 cm to 20 cm.

None of the other options can transmit or share information for payments among the team except the NFC. NFC is also suitable for this setup because only a small range is expected to be covered.

Three short square wood blocks measuring 3.5 per side support a machine weighing 29500 lbs. What is the compressive stress in th
Ilya [14]

Answer:

D. 803 lbs

Explanation:

In order to find the compressive stress on all three blocks we first need to find the normal surface area of each:

Surface Area of 1 Block = 3.5 x 3.5

Surface Area of 1 Block = 12.25

Surface Area of all 3 Blocks = A = 3 x 12.25

Area = 36.75

Now, the stress is given by the following formula:

Stress = Force/Area

Stress = 29500 lbs/36.75

Stress = 802.72 lbs

Hence, the correct option will be:

<u>D. 803 lbs</u>
