Answer:
Option A
,
Explanation:
When the ball its thrown up, at half way of its flight it means half of its vertical height which is
.
potential energy = mgh
since it moved half way of height
P.E = 
This means for the body to have gained half of its P.E, it will loose half of its kinetic energy.
Final kinetic energy(
) = E/2
kinetic energy = 
let the final velocity at halfway flight be v1
= E/2
=
cross multiply we have
=
cancel m from both sides
= 
take the square root of both sides,


Thus our final velocities will be E/2 and 
Answer:
Release the pressure on the gas peddle
Explanation:
If you turn around to fast you cant make a tighter turn around but if its slow you can turn around tighter.
I think it’s cause no change i think
<span>the information gathered in a scientific investigation is called : Data
Data consists of qualitative measurement (which cannot be counted with numbers) and quantitative measurement (which could be counted with numbers), and the scientists rely on these datas to create a correct conclusion regarding the question that experimented within the investigation</span>
