A 200 g ball and a 530 g ball are connected by a 49.0-cm-long massless, rigid rod. the structure rotates about its center of mass at 130 rpm. Its rotational kinetic energy is approximately 1.39 Joules.

To find the rotational kinetic energy of the connected balls, we can use the formula:

Rotational Kinetic Energy (KE) = (1/2) * I * ω^2

where I is the moment of inertia and ω is the angular velocity.

The moment of inertia for a system of particles rotating about an axis can be calculated by adding the individual moments of inertia of each particle. In this case, we have two balls connected by a rod.

The moment of inertia of a point mass rotating about an axis passing through its center of mass is given by:

I = m * r^2

where m is the mass of the point mass and r is the distance of the mass from the axis of rotation.

Given:

Mass of the first ball (m1) = 200 g = 0.2 kg

Mass of the second ball (m2) = 530 g = 0.53 kg

Distance from the axis of rotation (r) = 49.0 cm = 0.49 m

Angular velocity (ω) = 130 rpm = 130 * 2π / 60 rad/s (converted to radians per second)

Calculating the moment of inertia for each ball:

I1 = m1 * r^2

I2 = m2 * r^2

Calculating the total moment of inertia for the system:

I_total = I1 + I2

Calculating the rotational kinetic energy:

KE = (1/2) * I_total * ω^2

Substituting the given values:

I1 = 0.2 kg * (0.49 m)^2

I2 = 0.53 kg * (0.49 m)^2

I_total = I1 + I2

ω = 130 * 2π / 60 rad/s

Calculate the rotational kinetic energy:

KE = (1/2) * (I1 + I2) * (130 * 2π / 60)^2

Substituting the values:

KE = (1/2) * ((0.2 kg * (0.49 m)^2) + (0.53 kg * (0.49 m)^2)) * ((130 * 2π / 60) rad/s)^2

Calculating the expression:

KE ≈ 1.39 J

Therefore, the rotational kinetic energy of the connected balls is approximately 1.39 Joules.

Answer:

neutron

Explanation:

So here, we use the equation:

W = ΔKE + ΔPE

Recall that: KE = 0.5mv^2, and PE = qdΔV/D

ΔKE = 0.5m(v2)^2 - 0.5m(v1)^2, where v2 and v1 are Initial and final velocity respectively.

ΔPE = PE2 - PE1

PE2 = 0, since all energy is converted to other forms, mainly kinetic energy.

PE1 = q(d1)ΔV/D

Here, W = 0.

0 = 0.5m(v2)^2 - 0.5m(v1)^2 + 0 - q(d1)ΔV/D

Simplifying a bit, and knowing that d1 = D,

0 = 0.5m((v2)^2 - (v1)^2) - qΔV

Moving qΔV to the other side,

qΔV = 0.5m((v2)^2 - (v1)^2)

Dividing by q and isolating ΔV,

ΔV = 0.5m * ((v2)^2 - (v1)^2) / q

Now, we have ΔV, which is the electric potential difference, in terms of all the variables we know.

m = 9.1 * 10^-31

v2 = 1 * 10^6

v1 = 5 * 10^6

q = 1.602 * 10^-19 (this is a well known constant)

ΔV = 0.5*9.1*10^-31 * ((5*10^6)^2 - (1*10^6)^2) / 1.602*10^-19

Solving and simplifying all of this, we get that

ΔV = 68.25 V

The bullet takes 0.0025 seconds to pass through the wooden plank of 5 cm thickness when it is traveling horizontally with an initial speed of 30 m/s and a final speed of 10 m/s.

The time taken by the bullet to pass through the wooden plank can be determined using the equation of motion for constant acceleration.

Given:
Initial speed (u) = 30 m/s

Final speed (v) = 10 m/s

Distance (s) = 5 cm = 0.05 m

To find the time taken (t), we need to calculate the acceleration (a) first. We can use the equation:

v² = u² + 2as

Rearranging the equation, we have:

a = (v² - u²) / (2s)

Substituting the given values:

a = (10² - 30²) / (2 * 0.05)

Simplifying the expression:

a = (-800) / (0.1)

a = -8000 m/s²

The negative sign indicates that the acceleration is in the opposite direction of the initial velocity.

Next, we can use the equation of motion:

v = u + at

Substituting the values:

10 = 30 + (-8000) * t

Simplifying the equation:

-8000t = -20

Dividing by -8000:

t = 20 / 8000
t = 0.0025 s

Therefore, the time taken by the bullet to pass through the wooden plank of 5 cm thickness is 0.0025 seconds.


To find the time taken by the bullet to pass through the wooden plank, we need to calculate the acceleration first using the equation of motion.

By rearranging the equation and substituting the given values, we can find the acceleration.

Then, using the equation of motion again, we can solve for time.

The negative sign in the acceleration indicates that it is in the opposite direction of the initial velocity.

The resulting time is 0.0025 seconds.

El automóvil recorre una distancia de 11.806 metros antes de deternerse por completo.

Explanation:

De acuerdo con el enunciado, el conductor nota la luz roja, empieza a decelerar 0.5 segundos después y decelera hasta detenerse. La distancia total recorrida por el automóvil desde el instante en que el conductor nota la luz roja (\(\Delta s_{T}\)), medida en metros:

\(\Delta s_{T} = \Delta s_{1}+\Delta s_{2}\) (1)

Donde:

\(\Delta s_{1}\) - Distancia recorrida a velocidad constante, medida en metros.

\(\Delta s_{2}\) - Distancia recorrida hasta alcanzar el reposo, medida en metros.

Si suponemos que la segunda etapa describe un movimiento uniformemente acelerado, entonces la distancia recorrida total que representada por la siguiente fórmula:

\(\Delta s_{T} = v_{o}\cdot \Delta t_{o} + \frac{v_{f}^{2}-v_{o}^{2}}{2\cdot a}\) (2)

Donde:

\(v_{o}\) - Velocidad inicial del automóvil, medida en metros por segundo.

\(v_{f}\) - Velocidad final del automóvil, medida en metros por segundo.

\(\Delta t_{o}\) - Tiempo de reacción del conductor, medido en segundo.

\(a\) - Aceleración, medida en metros por segundo al cuadrado.

Si conocemos que \(v_{o} = 16.667\,\frac{m}{s}\), \(v_{f} = 0\,\frac{m}{s}\), \(\Delta t_{o} = 0.5\,s\) y \(a = -40\,\frac{m}{s^{2}}\), entonces la distancia recorrida total es:

\(\Delta s_{T} = \left(16.667\,\frac{m}{s} \right)\cdot (0.5\,s)+\frac{\left(0\,\frac{m}{s} \right)^{2}-\left(16.667\,\frac{m}{s}\right)^{2}}{2\cdot \left(-40\,\frac{m}{s^{2}} \right)}\)

\(\Delta s_{T} = 11.806\,m\)

Explanation:

Answer:

A. manipulate the independent variable

9) A vector describe as a quantity that has both magnitude and direction. 10) We use vectors to describe in physics in physical quantities, including displacement, velocity, acceleration, force, momentum, and torque.

The vector is typically represented by an arrow, with the length of the arrow representing the magnitude of the vector and the direction of the arrow representing the direction of the vector. In addition to the magnitude and direction, vectors also have a starting point and an end point. Vectors can be added together to obtain a resultant vector that represents the sum of the individual vectors. Vectors can also be subtracted, multiplied by a scalar, or divided by a scalar.

For example, displacement is a vector that describes the distance and direction between two points. Velocity is a vector that describes the speed and direction of motion and acceleration is a vector that describes the rate at which velocity changes. Force is a vector that describes the push or pull on an object and momentum is a vector that describes the motion of an object and its resistance to change. Torque is a vector that describes the rotational motion of an object. So therefore vectors are an important tool for physicists because they allow them to describe physical quantities in a way that is both concise and precise.

The interference causes certain wavelengths of light to cancel out, resulting in the appearance of colored fringes. In this case, the thickness of the disk causes destructive interference for wavelengths of light that appear red-blue, leaving only the green-red fringes visible.

The temperature of lemonade decreases from 29 °C to 8 °C.

The mass of lemonade, M = 0.32 kg = 320 g

The specific latent heat of fusion of ice = 3.4 × 10⁵ J/kg

Specific heat capacity of water = 4.2 × 10³ J/kg °C

a) The heat energy required to melt 1 kg of ice = 3.4 × 10⁵ J

So, the heat energy to melt 1 gram of ice = 340 J

Therefore, the energy required to melt 80 grams of ice = 340 × 80 = 27200 J

b) The formula for the energy gained by the melted ice from the lemonade is:

Q = mCΔT

Where m is the mass, C is the specific heat capacity, and ΔT is the change in temperature.

If a coherent light of wavelength 519 nm passes through two slits, the separation of the two slits is approximately 0.0604 mm.

To calculate the separation of the two slits in a double-slit interference pattern, we can use the equation for the fringe separation:

d * sinθ = m * λ

Where:

d is the separation of the slits,

θ is the angle of the bright fringe,

m is the order of the fringe, and

λ is the wavelength of the light.

In this case:

λ = 519 nm = 519 × 10⁻⁹ m,

m = 1 (assuming we're considering the first-order bright fringe),

θ = tan⁻¹(y / L), where y is the fringe separation and L is the distance to the screen.

Given that adjacent bright fringes are 4.00 mm apart (y = 4.00 mm = 4.00 × 10⁻³ m) and the screen is 4.6 m away (L = 4.6 m), we can calculate the angle θ:

θ = tan⁻¹(y / L) = tan⁻¹(4.00 × 10⁻³ / 4.6) ≈ 0.00087 rad

Now, substituting the values into the equation, we can solve for the separation of the slits (d):

d * sin(0.00087) = (1) * (519 × 10⁻⁹)

d = (519 × 10⁻⁹) / sin(0.00087)
