The moment of inertia of the flywheel is approximately 0.0337 kg·m^2.

To solve this problem, we can use the formula for rotational kinetic energy:

KE = (1/2) I ω²

where KE is the kinetic energy of the flywheel, I is its moment of inertia, and ω is its angular velocity.

We can first convert the angular velocity from revolutions per minute (rpm) to radians per second (rad/s):

ω = (11000 rpm) * (2π rad/rev) * (1 min/60 s) = 1146.13 rad/s

Next, we can plug in the values for KE and ω and solve for I:

KE = 4.9 MJ = 4.9 × 10⁶ J

ω = 1146.13 rad/s

(1/2) I ω² = KE

(1/2) I (1146.13 rad/s)² = 4.9 × 10⁶ J

I = (2 * 4.9 × 10⁶J) / (1146.13 rad/s)²

I = 0.0337 kg·m²

Therefore, the moment of inertia of the flywheel is approximately 0.0337 kg·m².

The power of the man is approximately 43.87 Watts.

First, let's convert the time taken to run up the hill from minutes to seconds:

t = 15 minutes = 900 seconds

Next, let's calculate the work done by the man to climb the hill:

Work = force x distance

= weight x height

= mgΔh

= (100 kg)(9.87 m/s^2)(40 m)

= 39,480 Joules

Now, let's calculate the power:

Power = Work / Time

= 39,480 J / 900 s

= 43.87 Watts

Therefore,  the power of a man weighing 100kg if he runs to the top of a hill of height 40meters on 15minutes is 43.87 Watts.

The final form that a star takes when it dies depends on its mass. For a star with a mass similar to that of the Sun, it will eventually exhaust the nuclear fuel in its core and evolve into a red giant star, expanding to hundreds of times its original size. After the red giant phase, the outer layers of the star will be expelled into space in a process called a planetary nebula, leaving behind a hot, dense core called a white dwarf.

For more massive stars, the final stages of their evolution can include supernova explosions, leaving behind a neutron star or a black hole. The exact details of a star's evolution and final form depend on its mass and other properties, such as its metallicity and rotation rate.

In summary, a star that is 10 billion years old may eventually become a red giant and then a white dwarf, but the exact fate of the star depends on its mass and other properties.

The distance travelled by an object is equal to the magnitude of the displacement when the object moves in a straight line without changing direction.

Distance refers to the total length covered by an object during its motion, regardless of the direction. Displacement, on the other hand, is a vector quantity that represents the shortest path between the initial and final positions of an object, considering the direction.

When an object moves in a straight line without changing direction, the distance travelled is equal to the magnitude of the displacement because the path followed by the object coincides with the displacement vector. This occurs when there are no changes in direction, such as when an object moves along a straight road or a linear track.

However, when an object changes direction during its motion, the distance travelled will be greater than the magnitude of the displacement.

Answer:

Explanation:

Acceleration is the change in velocity with respect to time.

Acceleration = change in velocity/Time

Acceleration = final velocity - initial velocity/Time

Given initial velocity = 10m/s

Final velocity = 20m/s

Time taken = 4s

Acceleration = 20-10/4

Acceleration = 10/4

Acceleration =2.5m/s²

For the second part of the question:

Given parameters

initial velocity = 15m/s

acceleration = -3m/s²

time = 4seconds

a = v-u/t

-3 = v-15/4

cross multiply

-12 = v-15

add 15 from both sides

-12+15 = v-15+15

3 = v

Hence the final velocity of the car is 3m/s

Similitudes y diferencias entre los músculos de los peces y los de los animales terrestres.

Explicación:

Los músculos de los peces se diferencian del músculo de los animales terrestres porque los peces tienen músculos rojos, rosados y blancos. También tienen tejido muscular de pescado que se compone de músculo estriado al igual que el músculo de los animales terrestres. La mayor parte del tejido muscular de los peces es de color blanco, pero muchos peces también tienen una cierta cantidad de tejido oscuro de color marrón o rojizo. El músculo oscuro se encuentra justo debajo de la piel a lo largo del costado del cuerpo.

Coulomb's law is express as:

1.0 c of charge is at one corner of a square of side 0.30 m. -1.0 c is at an adjacent corner. the potential is chosen so that v approaches 0 very far from the charges. the potential at point a is zero,

The potential at point A in the square can be calculated by summing the contributions from the charges, considering the distances between the charges and point A. Now, let's explain the answer in more detail. We can use the formula for the potential due to a point charge, which is given by:

\(\[ V = \frac{kQ}{r} \]\)

Where V is the potential, k is the electrostatic constant (approximately \(8.99 \times 10^9 N m^2/C^2\)), Q is the charge, and r is the distance from the charge to the point where the potential is being calculated.

In this case, we have a charge of +1.0 C at one corner and a charge of -1.0 C at an adjacent corner. Let's assume that point A is located at the midpoint of the side of the square between these two charges. The distance between the charges and point A is equal to the length of the side of the square, which is 0.30 m. To calculate the potential at point A, we can sum the contributions from each charge. The potential due to the +1.0 C charge can be calculated as:

\(\[ V_1 = \frac{kQ_1}{r_1} \]\)

And the potential due to the -1.0 C charge can be calculated as:

\(\[ V_2 = \frac{kQ_2}{r_2} \]\)

Since the potential approaches zero very far from the charges, we can assume that the contributions from each charge cancel each other out, resulting in a net potential of zero at point A. Hence, the potential at point A is zero.

The potential at point A is 0 volts.

The potential at point A can be found by considering the contribution from each charge to the total potential. Let's start by calculating the potential due to the first charge (1.0 C) at point A. The potential due to a single point charge is given by the equation V = k * Q / r, where V is the potential, k is the electrostatic constant (9 x 10^9 Nm^2/C^2), Q is the charge, and r is the distance between the charge and the point of interest.

In this case, the distance between the first charge and point A is the diagonal of the square, which can be calculated using the Pythagorean theorem as d = √(0.3^2 + 0.3^2) = 0.424 m. Plugging in the values, we have V1 = (9 x 10^9 Nm^2/C^2) * (1.0 C) / (0.424 m) = 2.12 x 10^10 V.

Now, let's calculate the potential due to the second charge (-1.0 C) at point A. Following the same steps, we find V2 = (9 x 10^9 Nm^2/C^2) * (-1.0 C) / (0.424 m) = -2.12 x 10^10 V.

Finally, to find the total potential at point A, we add the potentials due to each charge: V_total = V1 + V2 = 2.12 x 10^10 V + (-2.12 x 10^10 V) = 0 V.

Therefore, the potential at point A is 0 volts.

4. Hana interviews and advises a person who has been accused of a crime.

6. Dewayne creates the paperwork for a business contract.

For strings between blocks:

(a) The largest upward acceleration is 0.014 m/s²

(b) The string between the two blocks break.

To find the largest upward acceleration, the tension in the string between the blocks is equal to the gravitational force acting on the lower block. The tension in the string pulling the combination upward is equal to the gravitational force acting on the combination.

a) The gravitational force acting on the lower block is the weight of the lower block (mass x acceleration due to gravity) = (240g x 9.8m/s²) = 2352 N.

The gravitational force acting on the combination is the weight of the combination (mass x acceleration due to gravity) = (540g x 9.8m/s²) = 5292 N.

Since the tension in the string between the blocks must not exceed 3.6 N, and the tension in the string pulling the combination upward must not exceed 7.8 N, the largest acceleration on the blocks without breaking either string is:

a = (3.6 N + 7.8 N) / 540 g = 0.014 m/s²

b) If the acceleration is slightly higher than this, the string that breaks is the one between the two blocks, as it is already under a lower tension than the string pulling the combination upward.

The length of the copper wire must be approximately 44.2 meters for it to have a resistance of 0.128 ohms, assuming a 14-gauge wire with a diameter of 1.63 mm and using the resistivity of copper.

To find the length of the wire, we can use Ohm's Law, which states that the resistance (R) is equal to the product of the resistivity (ρ), the length (L), and the cross-sectional area (A) of the wire, divided by the diameter (d) of the wire squared.

The formula can be written as:

R = ρ * (L / A)

Resistance (R) = 0.128 ohms

Resistivity of copper (ρ) = (1.68 × 10^-8) ohm-meter (at 20°C)

Diameter (d) = 1.63 mm = 0.00163 meters (converted from millimeters to meters)

We need to find the length (L) of the wire.

To calculate the cross-sectional area (A) of the wire, we can use the formula for the area of a circle:

A = π * (d/2)^2

Plugging in the values, we have:

A = 3.14159 * (0.00163 / 2)^2

A  ≈ 2.08 x 10^-6 square meters

Rearranging Ohm's Law to solve for the length (L), we get:

L = (R * A) / ρ

Substituting the given values:

L = (0.128 * 2.08 x 10^-6) / (1.68 x 10^-8)

L  ≈ 44.2 meters

The length of the copper wire must be approximately 44.2 meters for it to have a resistance of 0.128 ohms, assuming a 14-gauge wire with a diameter of 1.63 mm and using the resistivity of copper.
