Explanation:

The plane is 300000 kg

It is 11000 meters about the earth's surface.

g = 9.81

PE = mgh

PE = 300000 * 9.81 * 11000

PE = 3.24* 10^10

The Kinetic Energy

KE = 1/2  m * v^2

m = 300000

v = 250 m/s

KE = 1/2 300000 * (250 m/s)^2

KE = 9.375 * 10^9

Total Energy = 3.24 * 10^10 + 9.375 * 10^9

Total Energy = 4.17 * 10^10

9.375 * 10^9

The outlet velocity is found to be approximately 200 m/s, while the mass flow rate is approximately 1.26 kg/s.

To calculate the outlet velocity, we can use the principle of conservation of mass. According to this principle, the mass entering the pipe per unit time is equal to the mass exiting the pipe per unit time. Since the volumetric flow rate is constant, the product of velocity and cross-sectional area remains constant along the pipe. Using this principle, we can find the outlet velocity.

Given that the inlet velocity is 50 m/s and the inlet diameter is 40 mm (0.04 m), we can calculate the inlet cross-sectional area using the formula for the area of a circle: A = πr², where r is the radius. The inlet cross-sectional area is approximately 0.00126 m².

Similarly, using the outlet diameter of 20 mm (0.02 m), we can calculate the outlet cross-sectional area, which is approximately 0.000314 m².

Applying the conservation of mass principle, we can set up the equation:

Inlet velocity * Inlet cross-sectional area = Outlet velocity * Outlet cross-sectional area

Plugging in the known values, we get:

50 m/s * 0.00126 m² = Outlet velocity * 0.000314 m²

Solving for the outlet velocity, we find it to be approximately 200 m/s.

To calculate the mass flow rate, we multiply the density of water (considering the standard value of 1000 kg/m³) by the volumetric flow rate. Since the volumetric flow rate is constant, multiplying it by the density gives us the mass flow rate.

Therefore, the mass flow rate is approximately:

Mass flow rate = Volumetric flow rate * Density of water

Mass flow rate = Constant * 1000 kg/m³

Mass flow rate = 0.00126 m³/s * 1000 kg/m³

Mass flow rate ≈ 1.26 kg/s

Thus, the outlet velocity is approximately 200 m/s, and the mass flow rate is approximately 1.26 kg/s.

Interpolation gives more accurate data or points compared to extrapolation.

Interpolation can be a little easier than extrapolation.

Interpolation does not require one to extend the already existing data points, where extrapolation requires elaboration of the pattern, curve, or line.

Extrapolation:

This is a statistical method used to predict unknown values for points outside the range of the recorded data. It is used to extend a known sequence of values beyond the sampled area

Extrapolation: with Extrapolation, we can be less confident with the unknown values derived using this method. The method includes values from outside the sampled area, which makes the predictions diverge away from the true values. In curve fitting, this method is not preferred.

Extrapolation:

the ability to retrieve negative answers is one characteristic that makes it unique for interpolation. This statistical method allows one to extend the values in the range either forward or backward. This technique of extending values is responsible for attaining the negative values.

The angle of refraction for the light ray with the wavelength of 589nm traveling through air strikes a crown glass at 30.0° incidence is 19.2°.

Refraction is the quantity used to measure the amount of refraction taking place at any boundary when light passes between the two mediums.

Refractive index can be calculated using Snell's law, the formula for calculating angle of refraction is as follows:

n₁/n₂ = sinФ₁/sinФ₂

n₁. sin(i) = n₂. sin(r)

where, n₁ = refractive index of medium 1

n₂ = refractive index of medium 2

i = angle of incidence in air

r = angle of refraction in glass

Therefore, by putting the values in this formula we can get the angle of refraction.

(1) × sin(30°)=(1.52) × sin(r)

sin(r)= 1/2 × 1.52

sin(r) = 1/ 3.04

r = sin⁻¹(0.328)

The total distance traveled by the car is approximately 87.68 kilometers.

To find the total distance traveled, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, the car travels 50.0 km west and 72 km north. These distances form the legs of a right triangle, and the total distance traveled is the hypotenuse.

Using the Pythagorean theorem:

Total distance² = (Distance traveled west)² + (Distance traveled north)²

Total distance² = (50.0 km)² + (72 km)²

Total distance² = 2500 km² + 5184 km²

Total distance² = 7684 km²

The hydrogen transition that represents the absorption of a photon in the UV portion of the electromagnetic spectrum is Option E: n=1 to n=4.

In the hydrogen atom, the energy levels of the electrons are quantized, and transitions between these energy levels result in the emission or absorption of photons. The energy of a photon is directly related to the difference in energy between the initial and final states of the electron.

In this case, the transition from n=1 to n=4 represents the absorption of a photon in the UV portion of the electromagnetic spectrum. When an electron in the hydrogen atom absorbs a photon, it gains energy and jumps from the ground state (n=1) to the higher energy state (n=4). This transition corresponds to the absorption of UV light.

The energy of the photon absorbed is equal to the difference in energy between the n=4 and n=1 levels. The energy difference increases as the electron transitions to higher energy levels, which corresponds to shorter wavelengths in the UV portion of the electromagnetic spectrum.

It comes to a stop when ω = 0, which happens for

0 = 27 rad/s - (0.15 rad/s²) t

Answer:

False.

Explanation:

Mass is the amount of matter in a given object. Weight is the force acting on an object due to gravity.

Answer:

False

Explanation:

Weight is the act of pulling an object towards the earth surface so weight is a force to amount

To determine the position u of the mass at any time t, we can use the equation of motion for a mass-spring system without damping:n m * u''(t) + k * u(t) = 0

m = 2 lb / (32.2 ft/s^2) = 0.062 lb·s^2/ft

The spring constant k can be determined using Hooke's law:

k = F / x

where F is the force exerted by the mass and x is the displacement. In this case, the force F is the weight of the mass, and the displacement x is 6 in:

k = (2 lb) / (6 in) = (2 lb) / (6 in) * (1 ft/12 in) = 0.111 lb/ft

The equation of motion now becomes:

0.062 * u''(t) + 0.111 * u(t) = 0

To solve this second-order linear homogeneous differential equation, we assume a solution of the form u(t) = A * cos(ωt + φ).

Substituting this assumed solution into the equation of motion, we get:

-0.062 * A * ω^2 * cos(ωt + φ) + 0.111 * A * cos(ωt + φ) = 0

-0.062 * ω^2 + 0.111 = 0

Solving for ω, we get:

ω = sqrt(0.111 / 0.062) = 2.258 rad/s

From ω, we can determine the frequency f and period T:

f = ω / (2π) = 2.258 / (2π) ≈ 0.359 Hz

T = 1 / f ≈ 2.786 s

The amplitude A is determined by the initial conditions. When the mass is pulled down an additional 3 in (0.25 ft) and released, it reaches its maximum displacement, so A = 0.25 ft.

Therefore, the position u of the mass at any time t is given by:

u(t) = 0.25 * cos(2.258t)

To draw the graph of u(t), plot the position u on the y-axis and time t on the x-axis, using the equation u(t) = 0.25 * cos(2.258t). The graph will be a cosine wave with an amplitude of 0.25 ft.

The moment of inertia about the rotation axis for the given playground toy, with two children sitting opposite each other, is approximately 145.35 kg·m².

To determine the moment of inertia about the rotation axis for the given playground toy, we need to consider the contributions from the seats and the two children.

Given:

Mass of each seat = 6.4 kg

Length of the rods (r) = 1.5 m

Mass of the first child (m₁)= 16 kg

Mass of the second child (m₂) = 23 kg

The moment of inertia of each seat can be calculated using the formula for the moment of inertia of a point mass about an axis:

\(I_{seat} = m_{seat times} r^2\)

For each seat, the moment of inertia is:

\(I_{seat} = 6.4 kg times (1.5 m)^2= 14.4 kg\cdot m^2\)

Now, to calculate the moment of inertia contributed by the children, we need to consider that the children are located opposite each other. Assuming the axis of rotation passes through the center of mass of the children-seats system, the moment of inertia for each child is:

\(I_{child} = m_{child times} r^2\)

For the first child (m₁):

\(I_1 = 16 kg times (1.5 m)^2 = 36 kgm^2\)

For the second child (m₂):

\(I_2 = 23 kg times (1.5 m)^2 = 51.75 kgm^2\)

Finally, we can calculate the total moment of inertia by summing the contributions from the seats and the children:

Total moment of inertia =\(4 times I_{seat} + I_1 + I_2\)

= \(4 times (14.4 kgm^2) + 36 kgm^2 + 51.75 kgm^2\)

= \(57.6 kgm^2 + 36 kgm^2 + 51.75 kgm^2\)
