Answer:
A Standard Lens
Explanation:
Since David wants to take pictures of people around him and also the objects far away, a standard lens would be fit for that.
Answer:
5, 10 and 16
Explanation:
The sum of their ages is √961 = 31
If Joe is x years old, the equation that follows is:
x + (x+5) + (x+5+6) = 31
This simplifies to
3x = 31 - 11 - 5 = 15
so x=5
From that you can find
Joe = x = 5
Kate = x+5 = 10
Jody = x+5+6 = 16
Answer:
Centrifugation.
Explanation:
When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in centrifugation.
Centrifugation can be defined as the process of separating particles from a liquid solution according to density, shape, size, viscosity through the use of a centrifugal force. In order to separate these particles, the particles are poured into a liquid and placed in a centrifuge tube. A centrifuge is an electronic device used for the separation of particles in liquid through the application of centrifugal force. Once the centrifuge tube is mounted on the rotor of the centrifuge, it is spun rapidly at a specific speed thereby separating the solution; denser particles are forced to the bottom (by moving outward in the radial direction) and the lighter particles stay at the top as a result of their low density.
Answer:
a. WS-Trust
Explanation:
WS-Trust can be defined as a WS-specification as well as OASIS standard that help to provides extensions to WS-Security, in order to facilitate a mechanism for issuing, renewing, as well as validating of security tokens which is why the aim and objectives of WS-Trust is to help and enable applications to construct trusted SOAP message exchanges.
Nevertheless WS-Trust enables the issuance as well as the dissemination of credentials within several and various trust domains.
