Given that,
mass m = 110 lbs
Force of gravity in Newton, F =?
Since,
1 lbs = 0.45 kg
110 lbs = 110* 0.45 = 49.5 kg
Since, force of gravity equals the weight of the body.
F = W = mg = 49.5 * 9.81
F = 485.595 N
Force of gravity will be 485.595 N.
In order for motion to occur net force is greater than 485.595 N.
Answer:
1.147 %
Explanation:
= Density of mercury =
g = Acceleration due to gravity = 9.81 m/s²
h = Height of mercury = 8.69 m
Standard atmospheric pressure =
6.55 mmHg converting to Pa
Dividing air pressure by the above value
The fraction of atmospheric pressure is 1.147 %

Answer:
83km
Explanation:
Distance from the 256km marker to 138km marker.....is (256 - 138) = 118km
Then when he traces back to the 173km marker....he moves (173 - 138) = 35km but its in the opposite direction...so hence..its -35km(since when calculating displacement...direction has to be accounted for)...
Total displacement from the 256km marker
; 118 + (-35) = 83km
