Answer: c. A person who gains unauthorized access to digital data
Explanation:
Explanation:
the acceleration will be unchanged according to newton second law of motion
A standard 60 W light bulb has a voltage of 130 volts. So, we use this conversion, the Faraday's constant which is equal to approximately 96,500 Coulombs per mole electron, and the Avogadro's number equal to 6.022×10²³ particles/mole . The solution is as follows:
W = Energy/time
60 W = x J/1 s
x = 60 J = 60 C·V
(60 C·V)*(1/130 V)*(1 mole e/96,500 C)*(6.022×10²³ electrons/mole electron)
= 2.88×10¹⁸ electrons
It will provide a clear picture of current system functions before any modifications or improvements are made is a benefit if they use the four-model approach.
<u>Option: D</u>
<u>Explanation:</u>
The four model approach is followed by number of analyst which showcase that they construct the physical and logical model of both current and new system. The most important advantage of such approach is it portrays transparent image of ongoing system, before one apply any modification or variation. This is necessary because the flaws which generated earlier in system may affect the SDLC phases and outcome of such process may result into unsatisfied user by paying additional cost. This can be avoided by taking additional steps which make it worth it. The major disadvantage of such approach is the added time and cost of constructing model in both current system.
