The net force is determined is basically who is pushing harder in a specific direction.Like since there bith pushing in the same direction the net force is in the direction that they are pushing.
Speed = distance travelled/time
S = 6m/2s
S = 3m/s
Answer:
0.00188 m²
37500000
Explanation:
= Area of aorta
Radius of aorta = 0.01 m
= Velocity of blood through aorta = 0.3 m/s
= Area of capillaries
= Velocity of blood through capillaries =
= Radius of capillaries =
From continuity equation as the mass is conserved
Effective cross sectional area of the capillaries is 0.00188 m²
Area of capillaries is also given by
The number of capillaries is 37500000
So if a valid argument does have a false conclusion, it cannot have all true premises. Thus at least one premise must be false. ... If an invalid argument has all true premises, then the conclusion must be false. FALSE: It is possible for an invalid argument to have all true premises and a true conclusion.
