A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the period of the wave. (Unit = s)
Answers
Velocity of the wave is 1.7 m/s
Explanation:
As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second
So here we will have
Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength
So here the wavelength of the wave is given as
now we have
The wave period will be 1.42 s.
What is wave period?The time interval, expressed in seconds, separating two waves as they pass throughout a stationary point has been known as the wave period.
What is wave?A pulse seems to be a single disturbance, whereas a wave would be a persistent, repeated interruption of a medium.
Calculation of wave period
The frequency = 7 / 10 = 0.7 Hz
Wave period can be calculated by the formula:
Wave period = 1 / frequency
Put the value of frequency in above equation.
Wave period = 1 / 0.7
Wave period = 1.42 s
Therefore, the wave period will be 1.42 s

Describe the movement of molecules in an ice cube at the temperatures shown, and indicate whether the ice cube will change state.
Answers
Answer: The ice molecules expand and become stuck since the water is frozen and start to vibrate
Explanation:
According to the concept of thermal energy, as the temperature rises thermal energy increases and molecules start vibrating faster and ice changes it's state to water that is from solid to liquid.
What is thermal energy?Thermal energy is defined as a type of energy which is contained within a system and is responsible for rise in temperature.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.
Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance containing molecules or atoms are vibrating faster.
These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the number of collision of particles , higher is the thermal energy.

What is the gamma factor for an object moving at 0.5c?
A. 0.866
B. 0.707
C. 1.15
D. 1.41
Answers
Answer:1.15
Explanation:
Answer:
C. 1.15
Explanation:
We can calculate the gamma factor for an object moving at 0.5c, using the formula:
γ = 1/√(1 - v^2/c^2)
--------
where v is the velocity of the object and c is the speed of light.
Substituting v = 0.5c, we get:
γ = 1/√(1 - 0.5^2) = 1/√(1 - 0.25) = 1/√0.75 ≈ 1.155
--------
Therefore, the gamma factor for an object moving at 0.5c is approximately 1.155.

What do scientists know about the future of the universe?
what dark matter is made of
why the expansion of the universe is accelerating
that stars will eventually burn out causing the universe to become cold and dark
that galaxies spin much slower than they should based on visible matter
Answers
Answer:
Gravity will cause a closed universe to collapse back on itself ending in the Big Crunch. scientific predictions about the future of the universe are based on the idea that the effect of gravity on matter determines the shape of the universe which then determines its future
Scientists know about the future of the universe and that stars will eventually burn out causing the universe to become cold and dark. Therefore, option C is correct.
What is the future of the universe?All of the stars and galaxies will ultimately run out of energy as the universe expands, and the universe will cool down, resulting in the "Big Chill." It will take an indefinite amount of time for gravity to stop the universe's expansion if its density is equal to the critical density.
There won't be any other galaxies visible outside of our own. The universe will then actually become cold, dark, and empty once the stars have burned out.
Scientists know about the future of the universe and that stars will eventually burn out causing the universe to become cold and dark. Therefore, option C is correct.

Answer:

When a lens produces light rays that are parallel, the image is: C. non-existent.
A ray diagram can be defined as the graphical representation of the possible paths light takes from one point (source) to another.
Hence, a ray diagram is a graphical representation of how light interacts with a boundary, so as to help us view a point on the image of an object.
Basically, the characteristics of an image produced from a lens or mirror can be determined by drawing a ray diagram of the possible paths taken by light.
On a ray diagram, an image produced from a lens is non-existent when the lens produces light rays that are parallel because the refracted rays of light neither diverge nor converge.
In conclusion, an image cannot be formed (non-existent) when a lens produces light rays that are parallel, due to refraction.

Si la rapidez lineal de un móvil que se desplaza con MCU se triplica y el radio se mantiene constante, entonces la fuerza centrípeta:
Answers
Answer:
F' = 9 F
Explanation:
The question says that, "If the linear speed of a mobile moving with MCU is tripled and the radius remains constant, then the centripetal force:"
The formula for the centripetal force is given by :
[tex]F=\dfrac{mv^2}r{}[/tex]
Where
m is the mass of the object
v is the velocity
r is the radius of path
If the linear speed us tripled, v' = 2v, r = constant, then the new centripetal force is given by :
[tex]F'=\dfrac{mv'^2}r{}\\\\F'=\dfrac{m(3v)^2}{r}\\\\=\dfrac{mv^2}{r}\times 9\\\\F'=9F[/tex]
So, the new force becomes 9 times of the initial force.

This object is located 13.0 cm to the left of the lens and the image forms at 20.8 cm to the right of the lens.
What is the focal length of the lens?
Answers
Answer:
0.125 cm
Explanation:
1/f = 1/d¡ + 1/d。
Find the focal point
(13.0^-1 + 20.8^-1) = 0.125 m
Focal point = 0.125 m
The object placed in front of mirror forms an image on the opposite side of the mirror. The focal length of the lens is 0.125 m.
What is focal length?Focal length is the distance between the lens and the image sensor when the object is in focus.
The focal length can be find out by using lens maker formula.
1/f = 1/d¡ + 1/d。
1 / 13.0 + 1 / 20.8
f = 0.125 m
Thus, the focal length of the lens is 0.125 m.
