Nuclear energy is the stored potential energy in the nucleus of an atom. This form of energy is released either when unstable nucleus splits into smaller nuclei , known as fission, or when nuclei fuse together, a process known as fusion. Compared to this, light energy is a form of electromagnetic radiation such that it is composed of photons, which are small packets of light energy. Each photon has a characteristic wavelength, frequency, etc. Light energy has photons which have no mass whereas nuclear energy comes from nucleus, and involves mass.

Lisa [10]

Out of the following given choices;

A) It is always difficult to get a project like this approved. This study will help them convince the local community to support the project.

B) If they do not perform the study, and there is a problem during the dredging project, the media could make them look bad.

C)The study will weigh the benefits against the negative impacts so an informed decision can be made.

D)The study will demonstrate the local government's concern for the community's safety.


The answer is; C

Dredging can have a negative impact on the marine environment. Destruction of this ecosystem could have reverberating effects that affect the communities that rely on this ecosystem for livelihoods, such as fishermen. An environmental and feasibility study will help weigh the benefits and demerits of the project and allow for an informed decision to be made.

A student plucks a fixed-end string, creating a standing wave with 6.00 nodes (including any nodes at the ends). The string is t
Vesna [10]

1) 2.5 wavelengths

2) 0.208 m

3) 1731 Hz

Explanation:

1)

Standing waves are waves that do not propagate, but instead the particles of the medium just oscillate around a fixed position. Examples of standing waves are the waves produced on a string with fixed ends.

The points of a standing wave in which the amplitude of the oscillation is always zero are called nodes.

The two fixed ends of the string are two nodes. In this problem, we have a total of 6 nodes along the string: this means that there are 4 additional nodes apart from the two ends of the string.

Therefore, this also means that the string oscillate in 5 different segments.

One wavelength is equal to 2 segments of the oscillation: therefore, since here there are 5 segments, this means that the number of wavelengths that we have in this string is

n=\frac{5}{2}=2.5

2)

The wavelength of a wave is the distance between two consecutive crests (or throughs) of the wave.

The wavelength of a standing wave can be also measured as the distance between the nth-node and the (n+2)-th node: so, basically, the wavelength in a standing wave is twice the distance between two nodes:

\lambda = 2 d

where

\lambda is the wavelength

d is the distance between two nodes

Here the length of the string is

L = 0.520 m

And since it oscillates in 5 segments, the  distance between two nodes is

d=\frac{L}{5}=\frac{0.520}{5}=0.104 m

And therefore, the wavelength is

\lambda=2d=2(0.104)=0.208 m

3)

The frequency of a wave is the number of complete oscillations of the wave per second.

The frequency of a wave is related to its speed and wavelength by the wave equation:

v=f\lambda

where

v is the speed

f is the frequency

\lambda is the wavelength

In this problem:

v = 360 m/s is the speed of the wave

\lambda=0.208 m is the wavelength

Therefore, the frequency is

f=\frac{v}{\lambda}=\frac{360}{0.208}=1731 Hz
