Answer:
The radius of the loop is 20.66 km
Explanation:
let the radius of the loop be r
mass of airplane is m
At the top, the pilot experiences two radial forces, which are
1) Gravitational force is mg
2) Centrifugal forces mv²/r out of the center
When the pilot experiences no weight,
then, mg = mv²/r
r = v² / g
= 450² / 9.8
= 20.66 x 10³3
= 20.66 km
i believe it is c but i could be wrong. (i’m sorry if i am)
Neither do.beacuse diffusion occurs due the random movement a substance's particals move from a higher concentration to a lower concentration down the concentration gradient.On the other hand osmosis is the movement of water molecules from a high water potential to a low water potential through a partially permeable membrane.thus no energy is required for them to do so.Active transport is a process that requires energy.
Answer:
B) krypton
Explanation:
Electron configuration of Br: [Ar] 3d10 4s2 4p5
Since we have the bromide ion with a negative charge, Br's atom acquired an electron and therefore another electron is added to the electronic configuration
.
Electron configuration of Br-: [Ar] 3d10 4s2 4p6
And now this electronic configuration coincides with that of Krypton as we see below
:
Electron configuration of Kr: [Ar] 3d10 4s2 4p6
Newton's third law<span> is for every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. </span>
