Answer:
55.80 g/s
Explanation:
From the question,
Flow rate = density×Area×velocity.
φ = ρ×A×V................... Equation 1
Where φ = flow rate of blood, ρ = density of blood, A = cross sectional area of blood, V = velocity of blood.
Given: ρ = 0.846 g/cm³, A = 1.36 cm², V = 48.5 cm/s.
Substitute these values into equation 1
φ = 0.846×1.36×48.5
φ = 55.80 g/s
Hence, the flow rate of the blood = 55.80 g/s
Matter is any substance that has mass and takes up space.
Answer:
7] Force = mass × acceleration
Force = 2 × 5
<u>Force = 10 N</u>
<u></u>
8] Velocity = acceleration due to gravity × time taken
Velocity = 9.8 × 12
<u>Velocity = 117.6 m/s</u>
Answer:
There's a video called Drawing Position vs Time Graphs made by MrDGenova that may help you, it's only three minutes long.
Explanation:
Hope that helps, if not, you could tell me what you don't understand and I could try explaining it in further detail.
Answer:
-20,000N
Explanation:
Force (N) = mass (kg) x acceleration (m/s²)
So,
Force = 2000 x -10
= -20,000N (Newtons)
