<span>It is false that energy in higher trophic levels is greater than energy at lower trophic levels. In the first trophic level you find the producers, in the second the primary consumers in the level following that the secondary consumers and in the last level the tertiary consumers. And only 10% of energy at one level is available to the next level. </span>
Answer:
a = 10 m/s²
F = 2000 N
m = 8.57 Kg
Explanation:
1) What is the acceleration of a 40 kg object pushed with a force of 400 N?
Acceleration of object = ?
Mass of object = 40 Kg
Force on object = 400 N
Solution:
Formula:
F = ma
by putting values,
400 N = 40 Kg × a
a = 400 N/ 40 Kg ( N = Kg.m /s²)
a = 10 m/s²
2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?
Acceleration of object = 2.5 m/s²
Mass of object = 800 Kg
Force on object = ?
Solution:
Formula:
F = ma
by putting values,
F = 800 Kg × 2.5 m/s²
F = 2000 Kg. m/s² ( N = Kg.m /s²)
F = 2000 N
3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?
Acceleration of object = 3.5 m/s²
Mass of object = ?
Force on object = 30 N
Solution:
Formula:
F = ma
by putting values,
30 N = m × 3.5 m/s²
m = 30 N / 3.5 m/s² ( N = Kg.m /s²)
m = 8.57 Kg
Disadvantages of asexual reproduction include: offspring compete for food and space, extreme temperatures can wipe out entire colonies, negative mutations can destroy many offspring.
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Answer:
Origin and Insertion
Explanation:
The origin is the point of attachment of a muscle that remains relatively fixed during contraction.
The insertion is the point or mode of attachment of a skeletal muscle to the bone or other body part that it moves.
