The third one
Explanation:
That's how reflections work.
Answer:
the mechanical advantage David had when using the pulley is 2.
Explanation:
Given;
load moved by David, L = 350 N
effort applied by David, E = 175 N
The mechanical advantage David had when using the pulley is calculated as;
Therefore, the mechanical advantage David had when using the pulley is 2.
The points with highest amplitudes are the antinodes. Antinodes are the points at which displacement of particle is maximum.
Hope this much clarifies your doubt.
(GABS) Overnight, all of the particles settled down to the bottom , and the larger particles were on the bottom and the smaller particles were on the top. Therefore, clay was on top, hummus was in the middle, and soil was on the bottom.
Particles dissolve is an unique way
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
