I believe the answer should be the last option. upon interaction, both objects should have the same charge after the electrons are transferred.
It is by gaining! I just learned this in school. Hope this helps:)
Answer:
Height = 53.361 m
Explanation:
There are two balloons being thrown down, one with initial speed (u1) = 0 and the other with initial speed (u2) = 43.12
From the given information we make the following summary
= 0m/s
= t
= 43.12m/s
= (t-2.2)s
The distance by the first balloon is

where
a = 9.8m/s2
Inputting the values

The distance traveled by the second balloon

Inputting the values

simplifying

Substituting D of the first balloon into the D of the second balloon and solving

Now we know the value of t. We input this into the equation of the first balloon the to get height of the apartment

I’ll say c Bc it make more since to find the travel distance
On a flat surface a moving bicycle has more kinetic energy than a stationary car
