Adittional Information:

The Universal Containers company used Einstein Analytics to create two datasets:

Dataset A: contains a list of activities with an "activitylD" dimension and a "userlD" dimension

Dataset B: contains a list of users with a "userlD" dimension

Answer Choices:

A. Use the dataflow transformation "delete" and set "userlD" as the deletion ID.

B. Use a combination of dataflow transformations: "augment" and "filter."

C. Use an external ETL tool to extract both datasets and delete records.

D. Use the recipe operation "delete" and set "userlD" as the deletion ID.

B. Use a combination of dataflow transformations: "augment" and "filter."

Answer:

B. Use a combination of dataflow transformations: "augment" and "filter."

A cube measures 3 cm on each side and has a mass of 25 g. What is its density.
Snowcat [4.5K]

Answer:

The density is:   0.926 \,\frac{g}{cm^3}

Explanation:

Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:

Vol = (3 \,cm)^3 = 27 \,\,cm^3

then the density becomes:

density=\frac{mass}{Vol} =\frac{25}{27} \,\frac{g}{cm^3} \approx 0.926 \,\frac{g}{cm^3}

The greatest ocean depths on the earth are found in the marianas trench near the philippines, where the depth of the bottom of t
Doss [256]
To find the pressure with a given data for the height, you are asked to get the hydraulic pressure. Hydraulic pressure has the following formula:

P = density*acceleration due to gravity*height

Assume that the density of seawater is the same as that for pure water,density = 1000 kg/m^3.

P = 1000 kg/m3*9.81m/s2*9100m
P = 89271000 Pascals or 89.271 megapascals

A girl on a spinning amusements park is 12m from the center of the ride and has a centripetal acceleration of 17 m/s^2. What is
Tanya [424]

Answer: 14.28 m/s

Explanation:

Assuming the girl is spinning with <u>uniform circular motion</u>, her centripetal acceleration a_{c} is given by the following equation:  

a_{c}=\frac{V^{2}}{r} (1)

Where:  

a_{c}=17 m/s^{2} is the <u>centripetal acceleration</u>

V is the<u> tangential speed</u>

r=12 m is the <u>radius</u> of the circle

Isolating V from (1):

V=\sqrt{a_{c}r} (2)

V=\sqrt{(17 m/s^{2})(12 m)}

<u />

Finally:

V=14.28 m/s This is the girl's tangential speed

If a beaker of water is placed under a broiler so that the heating coil is above the beaker. It is observed that only the surfac
bija089 [108]

Answer:

a

Explanation:

The most reasonable conclusion of the above phenomenon is that water is a poor conductor of heat. Basically water is an insulator. The heat from surface to the bottom of the beaker will take a lot of time. Moreover, no convection current is formed so, heat might not even reach the bottom surface. Hydrogen bonding also play a vital role in determining the thermal properties of water.

hence option A is correct

The light from many stars can be seen from earth. but there is a time delay between the time the light is emitted from the star
mrs_skeptik [129]
Stars are located at a distance which are measured in terms of light years. Light year is an Astronomical unit used to measure distance between distant Celestial bodies. 
1 light year = 9460730472580<span>800 metres 
But no star is located at a distance of 1 light year. Some stars are located at millions of light years and light travels ~ 3 x 10</span>⁸ m/s. Thus light takes time to reach our atmosphere.
