The nuclear power plant needs 95.217 kg of nuclear fuel or uranium 235 is used during the whole year to operate.

Here the nuclear power plant produces 1000MW of energy.

So, for one year the total energy that can be produced = 1000× 365× 24 = 8760000 MWh

Since the reactor has a 75% capacity, energy produced = 8760000×75/100 = 6750000 MWh. = 6.75×10⁹ kWh

Converting to joules = 6.75× 10⁹× 3.6× 10⁶ = 2.365×10¹⁶

Thermal efficiency is 33%. So, 2.365×10¹⁶ × 0.33

                                                 = 7.80×10¹⁵ J.

To find out the mass, we need to know the number of atoms. So converting the energy to meV.

7.80× 10¹⁵ × 6.242× 10¹² = 4.87 ×10²⁸ meV

From one atom 200 meV is produced.

So, number of atoms =  4.87 ×10²⁸/200 = 2.44×10²⁶ atoms.

No of moles = number of atoms/ Avogadro's number = 2.44×10²⁶/ 6.022 ×10²³ = 405.18 moles.

Mass = Number of moles× molar mass

        =405.18 × 235 = 95217.52 g = 95.217 Kg

So the amount of uranium 235 required by the nuclear reactor for an year is 95.217 g.

No, the normal force exerted on the book by the inclined plane and the weight force exerted on the book by the earth are not equal in magnitude.

The normal force acts perpendicularly to the inclined plane, while the weight force is a downward force. Since they are not in the same direction, their magnitudes cannot be determined.

The magnitude of the normal force is determined by the angle of the inclined plane. Since the normal force acts perpendicularly to the inclined plane, it can be calculated by finding the cosine of the angle of the inclined plane multiplied by the weight of the object.

For example, if the inclined plane has an angle of 30°, the normal force would be cos(30°) times the weight of the object. On the other hand, the weight force is determined by the gravitational force, which is a constant and always acts in the downward direction. Thus, the magnitude of the weight force is always equal to the weight of the object.

As a result, when an ultrasonic wave goes from muscle to bone, roughly 53.29% of it is reflected.

Ultrasound refers to sound waves with frequencies greater than the human hearing's highest audible limit. In terms of physical qualities, ultrasound is identical to "regular" sound, except that humans cannot hear it. This limit varies from person to person, but in healthy young individuals it is around 20 kilohertz.

Here,

So, we can first calculate the acoustic impedance of the muscle and bone:

Z1 = ρ1 * c1 = 1.06 × 10^3 kg/m^3 * 1540 m/s = 1.62 × 10^6 kg/m^2s

Z2 = ρ2 * c2 = 1.89 × 10^3 kg/m^3 * 1540 m/s = 2.88 × 10^6 kg/m^2s

And then use these values to calculate the reflection coefficient:

R = (Z2 - Z1) / (Z2 + Z1) = (2.88 × 10^6 kg/m^2s - 1.62 × 10^6 kg/m^2s) / (2.88 × 10^6 kg/m^2s + 1.62 × 10^6 kg/m^2s) = 0.73

The percentage of the ultrasound wave that is reflected can be calculated as the square of the reflection coefficient:

Reflection Percentage = R^2 * 100% = 0.73^2 * 100% = 53.29%

So, approximately 53.29% of the ultrasound wave is reflected when it passes from muscle into bone.

We know that (from Newton’s third law) the magnitude of the force on the second particle due to the first particle [tex]F_{12}[/tex] equals the magnitude of the force on the first particle due to the second particle [tex]F_{21}[/tex] , so:

                            [tex]F_{12} = F_{21}[/tex]

Given:

The initial acceleration of the first particle, a1 = 7.0 m/s^2

The initial acceleration of the second particle, a2 = 9.0 m/s^2

Mass of the first particle, m1 = 6.3 * 10^(-7) kg

Separation between the two particles, d = 3.2 * 10^(-3) m

Using Coulomb's law, the force between two charges q1 and q2 is given by:

F = k * |q1 * q2| / d^2

Where k is Coulomb's constant.

Coulomb's law is a fundamental law of electrostatics that describes the interaction between charged particles. It states that the force between two point charges is proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

Since the acceleration of a particle is directly proportional to the net force acting on it, we can write:

m1 * a1 = k * |q1^2| / d^2

m2 * a2 = k * |q2^2| / d^2

Dividing the first equation by the second equation, we get:

m1 * a1 / m2 * a2 = q1^2 / q2^2

(m1 * a1) / (m2 * a2) = (q1^2) / (q2^2)

m2 = m1 * (a1 / a2)

Substituting the known values:

m2 = 6.3 * 10^(-7) kg * (7.0 m/s^2 / 9.0 m/s^2)

m2 = 4.9 * 10^(-7) kg

The mass of the second particle is 4.9 * 10^(-7) kg.

To find the magnitude of the charge of each particle, we can rearrange the first equation:

q1^2 = m1 * a1 * d^2 / k

Substituting the known values:

q1^2 = 6.3 * 10^(-7) kg * 7.0 m/s^2 * (3.2 * 10^(-3) m)^2 / k

q1 = sqrt(6.3 * 10^(-7) kg * 7.0 m/s^2 * (3.2 * 10^(-3) m)^2 / k

=> q1 = q2 = 7.09 × 10^-11 C

Frictionless ramp: The acceleration of a box sliding down a frictionless ramp inclined at 30 degrees can be determined using the equation for gravitational acceleration:

a = g * sin(θ)

where a is the acceleration, g is the acceleration due to gravity (9.8 m/s^2), and θ is the angle of the ramp (30 degrees).

a = 9.8 * sin(30) = 4.9 m/s^2

Ramp with friction: If the coefficient of friction between the box and ramp is 0.34, the acceleration can be determined using the equation:

a = g * sin(θ) - μ * g * cos(θ)

where μ is the coefficient of friction.

a = 9.8 * sin(30) - 0.34 * 9.8 * cos(30) = 2.86 m/s^2

So the acceleration of the box sliding down a frictionless ramp inclined at 30 degrees is 4.9 m/s^2, and the acceleration if the coefficient of friction is 0.34 is 2.86 m/s^2.

The angular acceleration of the big wheel would be 0.59 rad/s².

The linear speed of a point on the circumference of a wheel can be related to its angular velocity (ω) by the equation v = ωr, where r is the radius of the wheel.

The angular acceleration (α) of the wheel can be found using the equation α = Δω/Δt, where Δω is the change in angular velocity and Δt is the time interval over which the change occurs.

In this scenario, the linear speed of the big wheel is given as 5.0 m/s and its radius is 0.50 m. Therefore, the initial angular velocity of the wheel is ω = v/r = 5.0 m/s / 0.50 m = 10 rad/s. The time interval over which the speed increases is given as 8.5 s.

The final angular velocity can be calculated using the equation ωf = ωi + αt, where ωi is the initial angular velocity and t is the time interval.

In physics, the final speed of an object in freefall (with no friction) depends only on the initial height from which it falls and the acceleration due to gravity, not on its mass.

According to the equation of motion, the final velocity of an object in freefall is given by v = sqrt(2gh), where v is the final velocity, g is the acceleration due to gravity (approximately 9.8 m/s^2 on the Earth's surface), and h is the initial height.

In this scenario, all objects, regardless of their mass, will reach the same final velocity if they are dropped from the same height. This is because the force of gravity acting on an object is proportional to its mass, but the acceleration due to gravity is the same for all objects. So, the final velocity of an object in freefall is not affected by its mass.

The angle at which William Tell must aim the arrow is approximately 32.2 degrees.

To find the angle at which William Tell must aim the arrow to hit the apple, you need to use the equation of motion for a projectile under constant gravitational acceleration.

Let's call the angle at which William aims the arrow "θ". Then, the horizontal velocity of the arrow (vx) can be found using vx = 35 m/s x cos(θ). The vertical velocity of the arrow (vy) can be found using vy = 35 m/s x sin(θ).

Using the kinematic equation for vertical motion under constant acceleration, we can find the time it takes for the arrow to reach the height of the apple:

vy = v0 + a x t

0 = 35 m/s x sin(θ) - 9.8 m/s² x t

t = (35 m/s x sin(θ)) / 9.8 m/s²

Next, use the horizontal velocity of the arrow and the time found above to find the horizontal distance it travels:

x = vx x t

x = 35 m/s x cos(θ) x (35 m/s x sin(θ)) / 9.8 m/s²

Finally, set x equal to the distance to the apple (27 m) and solve for θ using trigonometry:

27 m = 35 m/s x cos(θ) x (35 m/s x sin(θ)) / 9.8 m/s²

cos(θ) = sqrt(9.8 m/s² x 27 m / (35 m/s)²)

θ = arc cos(sqrt(9.8 m/s² x 27 m / (35 m/s)²))
