Answer:
The wolf's kinetic energy is 12000 J.
Explanation:
Kinetic energy is calculated as follows:
Where m stands for mass (in kg) and v for velocity in m/s, thus:
<h2>Answer with Explanation</h2>
A biozone is a portion of a layer of Earth’s crust where fossils are found. Biozones help scientists to excavate the fossils and help trace the path of evolution over time as it is a stratigraphic unit which is defined by its fossil content. There are several different ways in which biozones can be designated in terms of the zone fossils that they contain and often, some environmental factors that take place to consider the definition and interpretation of biozones.
Answer:
The speed of sound in this gas is 409.6 m/s.
Explanation:
The length of the column changes from 20 cm from resonance to resonance. Thus,
The length change from one resonance to resonance. so, there is 1 loop change. So,
ΔL = 1 loop = λ/2
ΔL = 20 cm (given)
Also, 1 cm = 0.01 m
So,
ΔL = 0.2 cm (given)
The wavelength is:
λ = ΔL×2
λ = 2x0.2 = 0.4 m
Given:
Frequency (ν) = 1024 Hz
<u>Velocity of the sound in the gas = ν×λ = 1024×0.4 m/s = 409.6 m/s</u>
