Answer:
The maximum allowable distance = 5 m
Explanation:
Data:
There will be three forces on the jib. Let the forces be denoted as:
, and the force on pole AB
To find the angle AB makes with the horizontal beam:
The load has a mass of 2 000 kg then, the force will be:
F = mg, where g = 9.81 m/s²
=
Breaking AB into its x and y coordinates:
Then,
∑ = 0
∑
∑
so the components of the forces will be 30 656.2 N and - 3 372.18 N

Answer:
c. A program that offers discounts to libraries and schools ensuring they have affordable access to modern telecommunications and information services.
Explanation:
Federal E-Rate program refers to the Schools and Libraries Program of the Universal Service Fund managed by the Universal Service Administrative Company (USAC) and being directed by the Federal Communications Commission (FCC).
The program offers telecommunications and internet access to schools and libraries in the United States at discounts of between 20% and 90% in order to make the services affordable to them.
The discounts received by each of he beneficiary schools receive which is between the rage of 20% and 90% is determined by the degree of poverty and the urban/rural status of the population or students being served.
In the program, connectivity and maintenance services are provided by the Schools and Libraries Program, while school that applied to the program has to provide other items like software, hardware (e.g. computers), and among other items that will make then to use the connectivity provided.
I wish you the best.
Answer:
a)5.28 Å , b)3.73 Å , c)3.048 Å
Explanation:
the atoms are situated only at the corners of cube.Each and every atom in simple cubic primitive at the corner is shared with 8 adjacent unit cells.
Therefore, a particular unit cell consist only 1/8th part of an atom.
The lattice constant of a simple cubic primitive cell is 5.28 Å
We know formula of distance,
d =
a)(100)
a=5.28 Å
Distance = =5.28 Å
b)(110)
Distance = = 3.73 Å
c)(111)
Distance= = 3.048 Å
