A Boulder drops in the water and creates a wave with a period of 2s/cycle and a wavelength of .75 m/cycle. How fast is the wave moving ?
Answer:
v = 0.375 m/s
Explanation:
Given that,
The wavelength of a wave is 0.75 m/cycle
The period of a wave is 2s/cycle
We need to find the speed of the wave. We know that,
[tex]v=\dfrac{d}{t}[/tex]
Substitute all the values,
[tex]v=\dfrac{0.75}{2}\\\\v=0.375\ m/s[/tex]
So, the speed of the wave is equal to 0.375 m/s.

A particle of mass M is moving in the positive x direction with speed v. It spontaneously decays into 2 photons, with the original particle disappearing in the process. One photon has energy 233 MeV and moves in the positive x direction, and the other photon has energy 21 MeV and moves in the negative x direction. (5) (a) Draw a picture of this process. What is the total relativistic energy of the particle before its decay
Solution :
Mass of the particle = M
Speed of travel = v
Energy of one photon after the decay which moves in the positive x direction = 233 MeV
Energy of second photon after the decay which moves in the negative x direction = 21 MeV
Therefore, the total energy after the decay is = 233 + 21
= 254 MeV
So by the law of conservation of energy, we have :
Total energy before the decay = total energy after decay
So, the total relativistic energy of the particle before its decay = 254 MeV

Tristan is an engineer working on a design for a new roller coaster. He wants the car to shoot out of the station very fast but needs a superconductor to be able to accomplish this. He is looking at different materials to use on the tracks of the roller coaster. What is necessary for his material to function as a superconductor? Check all that apply. ОТ< То a solid metal conductivity a very cold temperature a low boiling point no resistance
Answer:
Superconducting materials can transport electrons with no resistance, and hence release no heat, sound, or other energy forms. Superconductivity occurs at a specific material's critical temperature (Tc). As temperature decreases, a superconducting material's resistance gradually decreases until it reaches critical temperature. At this point resistance drops off, often to zero, as shown in the graph at right.

Measure the resistance of the inductor using the DMM of the myDAQ and then write an equation that can predict the final (nonzero) value of the voltage across the inductor in your measurement. If the variations of the current of the inductor with time is desired, explain how either of the two voltages you measured can be used to calculate the current of the inductor
From the wording of the question, I'm suspecting that you have ...

anomalous expansion of water
Answer: Anomalous Expansion of water & its effects When water is heated from 00C to 40C it contracts continously instead of expanding. Conversely expands when cooled down from 40C to 00C . This expansion of water from 40C to 00C is called anomalous expansion. When heated from 40C to 1000C its expansion is normal like the expansion of other liquids. Since water contracts when heated from 00C to 40C and expands from 40C to 1000C , its volume is smallest and the density is maximum at 40C. Hence water is heaviest at 40C.
3. A boulder drops in the water and creates a wave with a period of 2 s/cycle and a wavelength of
.75 m/cycle. How fast is the wave moving?
Answer:
The wave moves with a velocity of 37.5 m/s
Explanation:
We know that the speed of a wave is given by:
V = f*λ
Where f is the frequency (the inverse of the period)
Then:
f = 1/T
And we know that T = 2 s/cycle
f = 1/(2 s/cycle) = (1/2) cycle/s
And λ is the wavelength, we know that:
λ = 75m/cycle.
Then the speed of the wave is:
v = ( (1/2) cycle/s)*(75m/cycle) = (75/2) m/s = 37.5 m/s
If distance between particle become half, the electric force
The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

Explanation:
A 6.80 $\mu C$ particle moves through a region of space where an electric field of magnitude 1230 N/C points in the positive $x$ direction, and a magnetic field of magnitude 1.32 T points in the positive $z$ direction. If the net force acting on the particle is 6.18E-3 N in the positive $x$ direction, calculate the magnitude of the particle's velocity. Assume the particle's velocity is in the $x$-$y$ plane.
Answer:
v = -227.785 m/s
Explanation:
The electric field exerts the following force on the electric particle:
F = qE
[tex]F = 6.65 \times 10^{-6} \times 1230[/tex]
[tex]F = 0.0081795 \ N[/tex]
The magnetic field exerts the following force on the particle::
F = qvB
[tex]F = 6.65\times 10^{-6} \times v \times 1.32[/tex]
[tex]F = 8.778 \times 10^{-6} \times v[/tex]
Total force acting is:
F = qvB + qE
[tex]6.18 \times 10^{-3} = 0.0081795 + 8.778 \times 10^{-6} \times v[/tex]
[tex]v = \dfrac{6.18 \times 10^{-3} -0.0081795 }{8.778 \times 10^{-6}}[/tex]
v = -227.785 m/s
A coin is resting on the bottom of an empty container. The container is then fi lled to the brim three times, each time with a diff erent liquid. An observer (in air) is directly above the coin and looks down at it. With liquid A in the container, the apparent depth of the coin is 7 cm, with liquid B it is 6 cm, and with liquid C it is 5 cm. Rank the indices of refraction of the liquids in descending order (largest fist).
a. nC, nA, nB
b. nA, nB, nC
c. nB, nA, nC
d. nC, nB, nA
e. nA, nC, nB
when we placed in the container of real depth assuming = d
if the container filled with liquid A then its apparent depth d' = 7cm
so the refractive index nA = real depth / apparent depth
= d/7cm = 0.1428d
if the container filled with liquid B then its apparent depth d' = 6cm
so the refractive index nB = real depth / apparent depth
= d/6cm = 0.166d
if the container filled with liquid C then its apparent depth d' = 5cm
so the refractive index nC = real depth / apparent depth
= d/5cm = 0.2d
Since the refractive index is inversely proportional to the apparent depth
then the refractive indices are nC > nB > nA

2. Compare and Contrast A fault cuts through
two layers of rock. Above sits a layer of sand-
stone. How does the age of the fault compare
to the ages of all three rock layers?
Explanation:
The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault labeled "E" cuts through all three sedimentary rock layers (A, B,and C) and also cuts through the intrusion (D). So the fault must be the youngest formation that is seen and known of.
The age of the fault A is in between rock B and intrusion D. Hence A is the youngest rock and C be the oldest rock here.
What are faults?A fault is a crack or region of cracks that separates two rock blocks. The blocks might move in relation to one another due to flaws. This movement may happen suddenly, like an earthquake, or it may happen gradually, like creep.
From a few millimeters to thousands of kilometers, faults can vary in length. Over geologic time, most faults cause recurrent displacements. The rock on one side of the fault abruptly shifts in relation to the other during an earthquake. The fault surface may be vertical, horizontal, or at any other arbitrary angle.
The principal of superposition states that, the oldest layer will be the bottom of the young rocks. Here, rock is A is above B and C. Hence, rock A is youngest than layer B and C.

A wave has a frequency of 35 Hz and a wavelength of 15 meters,
what is the speed of the wave?
Answer:
f lamda = c
Explanation:
525 m/s is the speed
A wave has a frequency of 35 Hz and a wavelength of 15 meters, Then the speed of the wave is 525 meters per second(m/s).
What is the speed of the wave?The speed of a wave is the distance that a wave travels per unit of time. It is a measure of how quickly the disturbance created by the wave is propagated through a medium. The speed of a wave can be calculated using the formula:
Speed = Frequency x Wavelength
Where the frequency = is the number of wave cycles per second
wavelength = is the distance between two consecutive points on the wave that is in phase (i.e., at the same point in their oscillation).
The speed of a wave depends on the properties of the medium through which it is traveling, such as its density, elasticity, and temperature.
Here in the question,
Speed = Frequency x Wavelength
Speed = 35 Hz x 15 meters
Speed = 525 meters per second(m/s).
Therefore, the speed of the wave is 525 meters per second.

A bicycle pump contains 200 cm3 of air and is connected to a bicycle tyre. The volume of the tyre is 800 cm3. The pressure of the air in the tyre (it is ‘flat’) is 1.0 atmosphere, the same as the air in the pump. (= volume1). What is the total volume of the air initially?
Please help me
Answer:
The total volume of the air is 1000 cubic centimeters.
Explanation:
Since the bicycle pump and the bicycle tyre have the same pressure, then the total volume of the air is the sum of the volume of each element, then we translate this into the following artihmetical expression:
[tex]V = 200\,cm^{3}+800\,cm^{3}[/tex]

An object of mass 12.9 kg enters a rough floor with speed of 10.1 m/s. The coefficient of friction between the floor and the object is 0.30 and the object moves 2.07 m before returning to a smooth surface (frictionless). What is the velocity of the object once it returns to the smooth surface
Answer:
vf = 9.48 m/s
Explanation:
From the law of conservation of energy we can write:
[tex]Kinetic\ Energy\ Lost = Work\ Against\ Friction\\\frac{1}{2}m(v_i^2 - v_f^2) = fd\\\frac{1}{2}m(v_i^2 - v_f^2) = (\mu W)d\\\frac{1}{2}m(v_i^2 - v_f^2) = (\mu mg)d\\\frac{1}{2}(v_i^2 - v_f^2) = \mu gd\\v_f^2 = v_i^2 - 2\mu gd[/tex]
where,
vf = final speed = ?
vi = initial speed = 10.1 m/s
μ = coefficient of friction = 0.3
g = acceleration due to gravity = 9.81 m/s²
d = distance covered = 2.07 m
Therefore,
[tex]v_f^2 = (10.1\ m/s)^2 - 2(0.3)(9.81\ m/s^2)(2.07\ m)\\v_f^2 = 102.01\ m^2/s^2 - 12.18\ m^2/s^2\\v_f = \sqrt{89.83\ m^2/s^2}\\[/tex]
vf = 9.48 m/s
