Question

How to calculate time ratio in vertically up with different velocities?

Answer 1

Things you need to know before we begin:

1. Equations of Kinematics
 v = u + at
 s = ut + 1/2 at^2
 v^2 - u^2 = 2as
 where,
 t - time
 v - velocity at time t
 u - velocity at time t = 0
 a - acceleration of the object
 s - distance traveled in t time

2. Value of Acceleration due to gravity ( 

Answer 2

Answer:

Explanation:Formal charges help in the selection of the lowest energy structure from the number of possible

Lewis structure.

Lowest energy structure is the one with a factor based on a pure covalent bond between the two

atoms.
