Firstly removing off one strip and it leaves electrons behind, so the strip becomes positively charged.
2. The roll however is not negatively charged because it is "earthed " by the hand holding it, thus excess negatives repel each other away through the hand.
3.Tearing off the next strip and once more it leaves electrons behind, the new strip is also positively charged and will repel the first strip.
4. Then, tear two strips apart and one will leave electrons behind on the other. Meaning that one strip is positive and the other is negative and they will attract each other.
Answer:
This conveyor belt should be connected to fixed pulleys in case their total effort is less than the load. But if it's not that, the belt should be connected to movable pulleys.
Explanation:
The volume of snow is on the lawn, in cubic meters is 5.75 x 10⁻³ m³.
<h3>
Volume of the lawn in cubic meters</h3>
The volume of snow is on the lawn, in cubic meters is calculated as follows;
V = ²/₃πr³
where;
r is the uniform depth
r = 14 cm = 0.14 m
V = ²/₃π(0.14)³
V = 5.75 x 10⁻³ m³
Thus, the volume of snow is on the lawn, in cubic meters is 5.75 x 10⁻³ m³.
