Answer:
2. mechanical weathering can produce smaller pieces of rock that have more surface area for chemical weathering to work Explanation:
Mechanical weathering involves activities of living organisms or some geological processes. The bigger rocks are usually reduced to smaller rocks and further reduction might be limited or not posibble mechanically. This reduced rocks now increases the surface area available for chemical weathering; which further reduces the sizes of the rocks below the size range of mechanical weathering. one will recall that the rate of chemical reaction increases with exposed surface area.
Answer:
10seconds
Explanation:
use the formula a=v final_v inital/time
The second one is the answer
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
Natural gas is the answer.
