Lever: see saw, pry bar, lever action door latches.
Wedge: scissors, screw, a knife.
Wheel and axle: office chairs, carts, wheeled carry-on luggage and toy cars.
Inclined Plane: stairs
The factors which are affected will be based on the distance or range between the charged objects A and B
<u>Explanation:</u>
<u>Definition:</u>
- The force, F among the two-point size charges A and B are divided by a range r is given by Coulomb formula.
F=9x10^9 AB/r²
<u>Factors:</u>
- If the range among them is doubled the force will be decreased to 1/4 of the initial value. And if the range is split, the force will be four times.
- If the range among them is tripled, the force will be decreased to 1/9 of the initial value. If the range is decreased to one-third of the new value, the force will rise to Nine times the initial value.
B. If all plants are watered at least once a day then they will all grow at least 1 cm a day.
All plants grow at different rates.
Hope this helps! XD
