Answer:
Diameter of riser =6.02 mm
Explanation:
Given that
Dimensions of rectangular plate is 200mm x 100mm x 20mm.
Volume of rectangle V= 200 x 100 x 20 
Surface area of rectangle A
A=2(200 x 100+100 x 20 +20 x 200)
So V/A=7.69
We know that
Solidification times given as
-----1
Lets take diameter of riser is d
Given that riser is in spherical shape so V/A=d/6
And
Time for solidification of rectangle is 3.5 min then time for solidificartion of riser is 4.2 min.
Lets take 

Now from equation 1

So by solving this d=6.02 mm
So the diameter of riser is 6.02 mm.
Answer:
D. a measure of how fast a machine performs work
Explanation:
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
Hence, the best description of power is that, it is a measure of how fast a machine performs work.
This can be calculated by using the mathematical expression below;

But we know that,
Answer:
Area required = 9.5 ft²
Explanation:
Step by step explanation is given in the attached document.
Answer:
Option C (IaaS) will be the correct answer.
Explanation:
- IaaS is essentially a cloud strategy that enables an individual or company to rent resources including such servers, networking devices including data or storage management. IaaS is a digital storage facility.
- PaaS can not provide root privileges as even the hosting company would control the network. Here, SaaS as well as DBaaS aren't important.
That will be the right answer to the question.
