Question

an aeroplane taking off from a field has a run of 500 m what is its acceleration and takeoff speed if its leaves at the ground after 10 seconds after the start

Answer 1

So according to the condition of the question

s=500
u=0
t=10

so by formula

s=ut+1/2at^2

500=0+1/2 a 10*10

500=5*10*a

a=500/50

a=10 m/s^2

now by another formula

v=u+at

v=0+1(10)

v=100 m/s

Answer 2

Answer:Lewis structure.

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

atoms.

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

Lewis structure.
