The displacement of the bird is 1.8 km...because displacement is the distanse of the object from mean position to the travelled position.....hope it helps
I think that the answer is c. good luck
Explanation:
According to the energy conservation,



= 
= 
v = 
= 
Formula for distance from the orbit is as follows.
S = 
= 
= 
Now, relation between time and distance is as follows.
T = 

or, f =
=
= 
Thus, we can conclude that the orbital frequency for an electron and a positron that is 1.50 apart is
.
Answer:
If theta is equal to 90, then both projectiles strike at the same distance from the projection point and projectiles are in air for the same time interval.
