d) False
e) False
Explanation:
a) False
For a diverging lens, the focal length is negative while it is positive for a converging lens
b) True
Image distances for virtual images are always negative and it also forms on the the same side of the lens as the object and is enlarged
c) True
d) False

e) False
Image distances for virtual images are always negative and it also forms on the the same side of the lens as the object and is enlarged
Since my givens are x = .550m [Vsub0] = unknown
[Asubx] = =9.80
[Vsubx]^2 = [Vsub0x]^2 + 2[Asubx] * (X-[Xsub0]
[Vsubx]^2 = [Vsub0x]^2 + 2[Asubx] * (X-[Xsub0])
Vsubx is the final velocity, which at the max height is 0, and Xsub0 is just 0 as that's where it starts so I just plug the rest in
0^2 = [Vsub0x]^2 + 2[-9.80]*(.550)
0 = [Vsub0x]^2 -10.78
10.78 = [Vsub0x]^2
Sqrt(10.78) = 3.28 m/s
Answer:
he peaks are the natural frequencies that coincide with the excitation frequencies and in the second case they are the natural frequencies that make up the wave.
Explanation:
In a resonance experiment, the amplitude of the system is plotted as a function of the frequency, finding maximums for the values where some natural frequency of the system coincides with the excitation frequency.
In a Fourier transform spectrum, the amplitude of the frequencies present is the signal, whereby each peak corresponds to a natural frequency of the system.
From this explanation we can see that in the first case the peaks are the natural frequencies that coincide with the excitation frequencies and in the second case they are the natural frequencies that make up the wave.

Physical science is the study of matter and energy, and the relationship between matter and energy.
E. The study of matter and energy, and the relationship between matter and energy
<u>Explanation:</u>
The study of issue and vitality and the associations between physicists concentrate such subjects as gravity, light, and time. Albert Einstein, a well known physicist, built up the Theory of Relativity.
Material science is the investigation of issue and vitality at all scales—from the littlest particles of the issue to the whole universe.
A geologist has practical experience throughout the entire existence of Earth. A sea-life scholar contemplates sea plants and creatures. A physicist ponders matter, vitality, and how they are connected.
There are three primary parts of science: physical science, Earth science, and life science. Physical science is the investigation of lifeless common items and the laws that administer them. It incorporates material science, science, and cosmology.
