Answer:
thus the coulomb force is F – 8.19x10-8N. this is also an attractive force, although it is traditionally shown as positive since gravitational force is always attractive. the ratio of the magnitude of the electrostatic force to gravitational force in this case is,thus,FFG – 2.27x1039 F F G – 2.27x 10 39.

It is false that scientific advances have led to decreased energy efficiency and waste reduction.
To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,

Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.

Replacing,


The height of the acorn above the meter stick can be calculated as,




Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is
