Answer:
Effort = 120 Newton
Explanation:
Given the following data;
Mechanical advantage = 6
Load = 780 N
To find the effort required to lift the weight;
Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.
Mathematically, the mechanical advantage is given by the formula;
Making effort the subject of formula;
Substituting into the formula, we have;
Effort = 120 Newton.
Answer:
B)because otherwise the packets will bounce back and forth from end to end repeatedly
Explanation:
Bus topology can be regarded as a kind of topology for a Local Area Network, it is one that has it's nodes connected to a single cable(backbone) and any break in the so called backbone, there will be failure in the entire segment. However a Terminator is usually attached to the end-points of a bus network so that the signal is absorbed by the Terminator and as a result of this the signal will not reflect back down the line. If there is no Terminator there would be bouncing back and forth of packet in an endless loop.It should be noted that a bus topology require a terminator because otherwise the packets will bounce back and forth from end to end repeatedly
