Answer: C) Exiting
Explanation:
If the string connecting the puck to the center is cut, there will be no net force on the puck. (The force of gravity is offset by the turntable.) The puck will not accelerate or change direction, so it will move at a constant speed in the direction it was moving at the time the string was cut. How does this relate to the boy whirling a yo-yo given at the start of this Exploration sheet
Solution :
In the context, it is given that a boy is whirling a yo-yo in the counter clockwise direction above his head.
Similarly when a pink puck is floating above the circular table in uniform circular motion. Now when the string connecting the pink puck is cu at the center, no net force will be acting on the puck and it will not change its direction nor accelerate. But the puck will move at a constant speed.
Both the scenarios are same . But incase of the boy playing with the yo-yo, we consider the gravity force.

Se infla hasta 3dm3 un globo de goma a una temperatura de 20ºC y se lo lleva a una temperatura de
30ºC. Calcular su nuevo volumen
Answer:
V2 = 4.5 dm³
Explanation:
Dados los siguientes datos;
Volumen inicial = 3 dm³
Temperatura inicial = 20°C Temperatura final = 30°C
Para encontrar el nuevo volumen V2, usaríamos la ley de Charles.
Charles afirma que cuando la presión de un gas ideal se mantiene constante, el volumen del gas es directamente proporcional a la temperatura absoluta del gas.
Matemáticamente, Charles está dado por;
[tex] VT = K[/tex]
[tex] \frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]
Dónde;
V1 y V2 representan los volúmenes inicial y final respectivamente.
T1 y T2 representan las temperaturas inicial y final, respectivamente.
Haciendo V2 como la fórmula del sujeto, tenemos;
[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]
[tex] V_{2}= \frac{3}{20} * 30 [/tex]
[tex] V_{2}= 0.15 * 30 [/tex]
V2 = 4.5 dm³

Light of wavelength 519 nm passes through two slits. In the interference pattern on a screen 4.6 m away, adjacent bright fringes are separated by 4.0 mm. What is the separation of the two slits
Answer:
The appropriate solution is "0.597 mm".
Explanation:
Given that:
Wavelength,
[tex]\lambda = 519 \ nm[/tex]
or,
[tex]=519\times 10^{-9}[/tex]
Distance,
[tex]D=4.6 \ m[/tex]
Separated by,
[tex]\beta = 4.0 \ mm[/tex]
or,
[tex]=4.0\times 10^{-3}[/tex]
As we know,
⇒ [tex]\beta=\frac{\lambda D}{d}[/tex]
or,
The separation of two slits will be:
⇒ [tex]d=\frac{\lambda D}{\beta}[/tex]
By putting the values, we get
[tex]=\frac{(519\times 10^{-9})(4.6)}{4.0\times 10^{-3}}[/tex]
[tex]=5.97\times 10^{-4}[/tex]
or,
[tex]=0.597 \ mm[/tex]
• Develop an explanation to demonstrate how frequency, wavelength, and infrared light are all
related to each other.
• Using this explanation, describe why each animal image is different from the other.
Answer:
The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
Explanation:
just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.

A boy stands between two vertical walls and fires a rifle. Under what condition will he hear a single echo from both walls? Calculate the distance between the walls if the single echo is heard six seconds later.
Answer:
d = 1,029 m
Explanation:
When the young man shoots the rifle the sound travels in all directions, if the young man is at the same distance from the two walls, as the speed of the wave is constant, he takes the same time to go to the wall and return for which he hears a single echo.
To calculate the distance let's use the uniform motion relationships
v = d / t
d = v t
As the speed is constant, the time to reach the wall is the same as it takes to go from the wall to the young man,
t = to / 2
t = 6/2
t = 3 s
d = 343 3
d = 1,029 m
A Piatma is a very hot gas comprised of freely moving positive and negative suale particles that are in random motion. Which of the following microscopic properties, together alwama held to have an observable macroscopic effect on the plasma when the plan is placed in the region that contains the magnetic field?
A. The particles have subatomically mal dimensions
B. The particles are charged
C. The particles are not all classified as fundamental particles
D. The particles are in random motion
Answer:
B. The particles are charged
Explanation:
We know that a moving charge particle in magnetic field experiences a magnetic force given by :
[tex]$\vec F = q (\vec v \times \vec B)$[/tex]
In the context, a very hot gas of piatma consists of freely moving positive particles as well as negative particles. Now when the plasma is placed in the region of a magnetic field, then it experiences a force and thus it shows that the particles are charged particles.
Hence , option (B) is correct.

In a double-slit experiment, the third-order maximum for light of wavelength 510 nm is located 17 mm from the central bright spot on a screen 1.6 m from the slits. Light of wavelength 670 nm is then projected through the same slits. Part A How far from the central bright spot will the second-order maximum of this light be located
Answer:
14.9 mm
Explanation:
We know dsinθ = mλ where d = separating of slit, m = order of maximum = 3 and λ = wavelength = 510nm = 510 × 10⁻⁹ m
Also tanθ = L/D where L = distance of m order fringe from central bright spot = 17 mm = 0.017 m and D = distance of screen from slit = 1.6 m
So, sinθ = mλ/d
Since θ is small, sinθ ≅ tanθ
So,
mλ/d = L/D
d = mλD/L
Substituting the values of the variables into the equation, we have
d = 3 × 510 × 10⁻⁹ m × 1.6 m/0.017 m
d = 2448 × 10⁻⁹ m²/0.017 m
d = 144000 × 10⁻⁹ m
d = 1.44 × 10⁻⁴ m
d = 0.144 × 10⁻³ m
d = 0.144 mm
Now, for the second-order maximum, m' of the 670 nm wavelength of light,
m'λ'/d = L'/D where m' = order of maximum = 2, λ' = wavelength of light = 670 nm = 670 × 10⁻⁹ m, d = slit separation = 0.144 mm = 0.144 × 10⁻³ m, L' = distance of second order maximum from central bright spot and D = distance of screen from slit = 1.6m
So, L' = m'λ'D/d
So, substituting the values of the variables into the equation, we have
L' = 2 × 670 × 10⁻⁹ m × 1.6 m/0.144 × 10⁻³ m
L' = 2144 × 10⁻⁹ m²/0.144 × 10⁻³ m
L' = 14888.89 × 10⁻⁶ m
L' = 0.01488 m
L' ≅ 0.0149 m
L' = 14.9 mm

g PRACTICE ANOTHER Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 30.3 m/s and train 2 at a speed of 22.5 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)
Answer:
f'= 607.8 Hz
Explanation:
This is a Doppler effect exercise due to the relative velocity of the sound source and the observer.
By the time the source and the observer are getting closer the expression is
f ’=[tex]f_o \ \frac{ v+ v_o}{v - v_s}[/tex]
where vs is the speed of the source, vo is the speed of the observer, if the bodies move away the signs are exchanged
in this case, train 1 emits sound, so its speed is v_s = 30.3 m / s and train 2 is the receiver of the sound v₀ = 22.5 m / s
let's calculate
f ’= [tex]520 \ ( \frac{343 + 22.5}{343 - 30.3} )[/tex]520 (343+ 22.5 / 343 - 30.3)
f'= 607.8 Hz

A charged particle of mass 0.0050 kg is subjected to a 5.0 T magnetic field which acts at a right angle to its motion. If the particle moves in a circle of radius 0.20 m at a speed of 2.0 m/s. what is the magnitude of the charge on the particle
Answer:
0.01 C
Explanation:
Applying,
F = qvBsinФ................ Equation 1
Where F = Force on the charged particle, q = charge on the particle, v = velocity, B = magnetic field, Ф = angle
Since the charged particle noves in a circle,
F = mv²/r................. Equation 2
Where m = mass of the particle, v = velocity of the particle, r = radius of the circle
Substitute equation 2 into equation 1
mv²/r = qvBsinФ
make q the subject of the equation
q = mv/(rBsinФ)............. Equation 3
Given: m = 0.005 kg, v = 2 m/s, r = 0.2 m, B = 5 T, Ф = 90° (Act at right angle)
Substitute these values into equation 3
q = (0.005×2)/(0.2×5×sin90°)
q = 0.01/(1)
q = 0.01 C

Suppose you have a Frisbee with a mass of 0.10 kg. You first throw it with a force of 5N and then change the force you throw it at to 20N. As your force increases, what is happening to the acceleration of your Frisbee?
Answer:
The acceleration increases.
Explanation:
From Newton's 2nd Law, we have [tex]\Sigma F=ma[/tex]. We can see that force is directly proportional to mass and acceleration. Therefore, as force increases, either mass or acceleration must increase as well, and vice versa. Since mass is maintained here, if you increase the force applied to the Frisbee, the acceleration will increase as well.
