Answer:

1. Clepsydra

2. Barometer

3. Chronometer

4. Se*tant

Explanation:

1. A clepsydra is a device that measures time by using a regulated fluid flow. It looks like a hour glass.

2. A barometer is a device that measures pressure. The level of liquid inside of its tubes changes with the atmospheric pressure change.

3. A chronometer is used to determine a position while knowing latitude, longitude, and altitude.

4. A se*tant has an arc of a circle and a movable arm pivoted at the center of the circle. It is used to view the horizon and also celestial bodies.

A pipe of 0.3 m outer diameter at a temperature of 160°C is insulated with a material having a thermal conductivity of k = 0.055

Alekssandra [29.7K]

Answer:

Q=0.95 W/m

Explanation:

Given that

Outer diameter = 0.3 m

Thermal conductivity of material

$K= 0.055(1+2.8\times 10^{-3}T)\frac{W}{mK}$

So the mean conductivity

$K_m=0.055\left ( 1+2.8\times 10^{-3}T_m \right )$

$T_m=\dfrac{160+273+40+273}{2}$

$T_m=373 K$

$K_m=0.055\left ( 1+2.8\times 10^{-3}\times 373 \right )$

$K_m=0.112 \frac{W}{mK}$

So heat conduction through cylinder

$Q=kA\dfrac{\Delta T}{L}$

$Q=0.112\times \pi \times 0.15^2\times 120$

Q=0.95 W/m

Time complexity of quick short

Irina-Kira [14]

Answer:

The time complexity will be "O(n log n)".

Explanation:

Many realistic Quick sort implementations choose a randomized special edition. The time complexity variable O(n Logn) was predicted in the randomized edition.
Throughout the randomized version, probably the most disgusting case is also conceivable, but by far the worst scenario for something like a given pattern does not exist as well as randomized Quick sort performs well throughout the practice.
