Answer:
0.021 kgm/s
Explanation:
using energy
change potential energy of the egg = change in kinetic energy of the egg
mgh = 1/2 mv² m in kg, h in meters
5.0g = 5.0/1000 kg= 0.005 kg
90 cm = 90 / 100 = 0.9 m
cancel m on both side
gh = 1/2 v²
make v subject of the formula
v = √2gh = √2×9.81×0.9 = √17.658 = 4.2 m/s that is the velocity of the egg on impact with floor and the initial velocity of the egg is zero.
impulse = m × Δv = 0.005 × 4.2 = 0.021 kgm/s
Natural Selection: <span>the process whereby organisms better adapted to their environment tend to survive and produce more offspring. hope this helps</span>
<span>Loss of biodiversity can result in a reduction in goods and services that are derived from the environments that have an impact on human health. This includes the availability of fresh water, food, and natural genes and chemical products important for human health. An example of effects of biodiversity loss is its impact on agriculture. Biodiversity loss leads to reduced agricultural yields</span>
i believe it is c.
because the amount of energy a consumer receives is decreased by 90% every trophic level.
for example, a herbivore would receive 10% of the energy that a plant would have stored.
