Answer:
Approximately , assuming that .
Step-by-step explanation:
When the force is constant, moving by in the direction of the force would do a work of .
However, in this example, as an increasing portion of the chain gets lifted up, the force lifting the chain would increase in size. Hence, apply the integral form of this equation.
Let denote the force required to lift the chain when the height above the ground is meters. At that moment, exactly of the chain would be above the ground. The mass of that much of the chain would be the mass of the whole chain.
.
Integrate with respect to :
.
In other words, it would take approximately of energy to raise one end of the chain to that height of .

Answer:
B
Step-by-step explanation:
That the answer Plss follow me thanks
Well to do this, we need to know the least common multiple (LCM) of 6 and 8. Lets list the factors out.
6, 12, 18, 24, 30, 36
8, 16, 24, 32, 40, 48
As we can see, the least common multiple of 6 and 8 is 24.
Now we know that there are 8 plates per package and 8 goes into 24 3 times, so naturally Shaniya needs 3 packages of plates
Hope this helped!!! :)
