Answer: N has to be lesser than or equal to 1666.
Explanation:
Cost of parts N in FPGA = $15N
Cost of parts N in gate array = $3N + $20000
Cost of parts N in standard cell = $1N + $100000
So,
15N < 3N + 20000 lets say this is equation 1
(cost of FPGA lesser than that of gate array)
Also. 15N < 1N + 100000 lets say this is equation 2
(cost of FPGA lesser than that of standardcell)
Now
From equation 1
12N < 20000
N < 1666.67
From equation 2
14N < 100000
N < 7142.85
AT the same time, Both conditions must hold true
So N <= 1666 (Since N has to be an integer)
N has to be lesser than or equal to 1666.
Answer:
9.7g / cm^3
Explanation:
To calculate a conbined density we must find the ratio between the sum of the masses and the sum of the volumes remembering that the equation to find the density is α=m/v, taking into account the above the following equation is inferred.
αc=copper density
αs=silver density
Vs=volume of silver
Vc=volume of copper
α= density of alloy
the density of the alloy is 9.7g / cm^3
Answer:
rB / rA = 3
Explanation:
The resistance of any conductor, can be expressed by the following equation:
where:
ρ = resistivity of the material
A = area through which the current is flowing
L = length of the object
If we are talking about wires, usually we approximate them as cylindrical objects, where A is the circular cross-section of the wire.
So, we can write the value of the resistance, as follows:
If we know that wire B is to have nine times the resistance of wire B, we can establish the following proportion between them:
Taking square roots on both sides, we finally get:
