Answer:
Habitat manipulation
Explanation:
Habitat manipulation, otherwise known as ecological engineering, is a technique of promoting natural enemies within an ecosystem by making thriving conditions more suitable for them.
<em>In this case, thriving conditions for the species (which happens to be predators and hence, natural enemies) were promoted via artificial introduction of food. </em>
To find momentum you multiply the mass and velocity.
91 × 7 = 637 kg-m/s
Answer:
Ei = 40J
Explanation:
Given the following data;
Efficiency = 50%
Energy output, Eo = 20 J
To find the amount of energy used by the mixer:
Efficiency = Eo/Ei * 100
Where;
Eo is the output energy.
Ei is the input energy.
Substituting into the formula, we have;
50 = 20/Ei * 100
Cross-multiplying, we have;
50Ei = 2000
Ei = 2000/50
Ei = 40J
Physical characteristics of matter include its mass<span>, weight, volume, and </span>density<span>. It also specifically describes its odor, shape, texture, and </span>hardness<span>. In addition, physical properties describe whether the object is a solid, a liquid, or a gas – its phase of matter at room temperature.</span>
