Answer:
6402.86 N
Explanation:
taking into account the energy-work theorem, we can write the following equation
Where F is the force, d is the distance, m is the mass, vf is the final velocity and vi is the initial velocity.
Solving for F, we get:
Replacing m = 830 kg, vf = 0 m/s, vi = 1.8 m/s, and d = 0.210 m, we get:
Therefore, the magnitude of the force is 6402.86 N
Answer:
Explanation:
given,
velocity factor = 4
Cross-sectional area of venules(A₁) = 10 cm²
cross sectional area of capillaries(A_2) = ?
continuity equation = Q = AV
now,
hence, the area of capillaries is equal to 2.5 cm₂
Density <em>ρ</em> is mass <em>m</em> per unit volume <em>v</em>, or
<em>ρ</em> = <em>m</em> / <em>v</em>
Solving for <em>v</em> gives
<em>v</em> = <em>m</em> / <em>ρ</em>
So the given object has a volume of
<em>v</em> = (130 g) / (65 g/cm³) = 2 cm³
