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.

A negative charge is moving across a room from south to north. A magnetic field runs from east to west. In what direction is the

erica [24]

Here is your answer

C. towards the floor

REASON:

Using Fleming's Left hand rule we can determine the direction of force applied on a moving charged particle placed in a magnetic field.

The direction of current will be just opposite to the direction of electron(negative charge) because current moves from positive to negative terminal whereas electron moves from negative to positive terminal.

So, direction of current- North to South

Now applying Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.
