Answer:
C. 1.3 x 10-11 F
I took the test and got this correct, hope this helps
Explanation:
Explanation:
Distance given to travel in south =4m
Distance given to travel in east=3 m
Total distance would be 4+3=7 M
&
Total displacement would be also 7 because he walks in south and east
And not in the same direction.

1. Eat a balanced diet and regular exercise. This is the best way because eating right and exercising are is more beneficial than just exercising.

Answer:
Approximately 
(assuming that the projectile was launched at angle of 
above the horizon.)
Explanation:
Initial vertical component of velocity:
.
The question assumed that there is no drag on this projectile. Additionally, the altitude of this projectile just before landing 
is the same as the altitude 
at which this projectile was launched: 
.
Hence, the initial vertical velocity of this projectile would be the exact opposite of the vertical velocity of this projectile right before landing. Since the initial vertical velocity is 
(upwards,) the vertical velocity right before landing would be 
(downwards.) The change in vertical velocity is:
.
Since there is no drag on this projectile, the vertical acceleration of this projectile would be 
. In other words, 
.
Hence, the time it takes to achieve a (vertical) velocity change of 
would be:
.
Hence, this projectile would be in the air for approximately .
