When making a celestial sphere, one would need to mark the celestial north pole, which is directly over Earth's north pole. You'd also need to mark the celestial south pole, directly over Earth's south pole.

The celestial equator which is a projection of Earth's equator into space. Finally the ecliptic, which is the path the sun follows as it appears to circle around the celestial sphere once each year. All celestial bodies can be projected onto a hypothetical sphere called the celestial sphere, which is centered on the Earth.

The other half of the celestial sphere is below the horizon, so an observer on the surface of the Earth may only view half of it at any given time. Even though the Earth's rotation constantly reveals fresh areas of the celestial sphere, unless the observer is situated at the equator, there will always be a portion of the sphere that is hidden.

The celestial sphere seems to rotate every day from east to west because of how the Earth spins on its axis, and stars appear to move in a circle around two locations in the sky.

The speed of the shark after it swallows the fish is calculated using the conservation of momentum principle. The total momentum before the collision is 5 kg * 1 m/s + 1 kg * 4 m/s = 9 kg * m/s. The total momentum after the collision is 5 kg * v, where v is the speed of the shark after the collision. Therefore, v = 9/5 m/s = 1.8 m/s. Thus, the speed of the shark after it swallows the fish is 1.8 m/s.

The speed of the shark after it has swallowed the 1-kg fish swimming toward it at 4 m/s is 3 m/s. This can be determined by conservation of momentum. Momentum is a vector quantity, meaning that the direction of the momentum must also be taken into account.

In this situation, the momentum of the shark before it swallows the fish is 5 kg⋅m/s due to its velocity of 1 m/s. After the shark has eaten the fish, the momentum is 6 kg⋅m/s due to the addition of the fish's momentum of 4 kg⋅m/s. Since momentum is conserved, the momentum of the shark after eating the fish is the same as the momentum of the shark before eating the fish. Since the mass of the shark does not change, the velocity must change to balance out the difference in momentum. This means that the velocity of the shark after eating the fish is 3 m/s.

(A) The moment of inertia about an axis passing through the intersection of the two segments will be the same if the rod is bent at the centre and the distance between all of the points and the axis stays constant i.e. Ia = 1/12 ML²

(B) Calculate the moment of inertia on a line connecting the two ends and passing through a point midway along it.

Determine the distance between the ends as a first step ( d )

After utilizing Pythagoras's principle

d =√2/2L

Determine the distance between the two axes as the next step ( x )

After utilizing Pythagoras's principle

x =√3/4/L

Compute the value of Ix as the last step.

the Parallel Axis Theorem is applied

Iₓ = Iₐ + Mx²

Iₓ = 1/12ML² + 1/4 ML²

Iₓ = 1/3ML²

The fundamental force that is most responsible for beta decay is the weak force. This force is responsible for the transformation of a neutron into a proton, electron, and antineutrino.

During beta decay, a neutron emits a W- boson which then decays into a proton, electron, and antineutrino. This results in the conversion of a neutron into a proton, with the electron and antineutrino carrying away the excess energy and momentum. In nuclear physics and particle physics, the weak interaction, which is also often called the weak force or weak nuclear force, is one of the four known fundamental interactions, with the others being electromagnetism, the strong interaction, and gravitation. The Standard Model of particle physics provides a uniform framework for understanding electromagnetic, weak, and strong interactions. An interaction occurs when two particles (typically, but not necessarily, half-integer spin fermions) exchange integer-spin, force-carrying bosons.

Answer:

The slit width a, must be equal to the wavelength λ

That is, every point on one side of the slit must have a corresponding point that is 180 degrees out of phase on the other side of the slit so the corresponding point on the screen receives no light,

This condition is also known as the Rayleigh criterion for the first dark fringe. It gives the angle at which the first dark fringe will appear in the diffraction pattern for a given wavelength of light and slit width.

When light waves pass through a single slit of width w, they diffract and create a diffraction pattern on a screen placed behind the slit. The pattern consists of a central bright fringe flanked by a series of alternating bright and dark fringes. The condition for the first dark fringe can be determined using the following formula:

sin θ = λ/w

where θ is the angle between the line normal to the slit and the direction of the dark fringe, λ is the wavelength of the light, and w is the width of the slit.

For the first dark fringe, the angle θ is equal to the smallest angle for which the path difference between the waves from the top and bottom edges of the slit is λ/2. This means that the condition for the first dark fringe is:

sin θ = λ/2w

Answer:

The total kinetic energy of the car can be divided into two parts: translational kinetic energy, due to the car's motion as a whole, and rotational kinetic energy, due to the rotation of the wheels about their axles.

The translational kinetic energy of the car is given by:

KE_translational = (1/2)mv^2

where m is the mass of the car and v is its speed.

The rotational kinetic energy of each wheel can be calculated as:

KE_rotational = (1/2)Iω^2

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

The moment of inertia of a uniform disk is given by:

I = (1/2)mr^2

where m is the mass of the disk and r is its radius.

The mass of each wheel is given as 12 kg, so the moment of inertia of each wheel is:

I = (1/2)(12 kg)(0.5 m)^2 = 1.5 kg·m^2

Assuming that the wheels are rolling without slipping, the angular velocity of each wheel can be related to the speed of the car by:

v = rω

where r is the radius of the wheel.

Solving for ω, we get:

ω = v/r

Substituting this expression into the equation for KE_rotational, we get:

KE_rotational = (1/2)(1.5 kg·m^2)(v/r)^2

Simplifying, we get:

KE_rotational = (3/8)mv^2

So the rotational kinetic energy of each wheel is (3/8) of the translational kinetic energy of the car.

The total rotational kinetic energy of all four wheels is therefore:

KE_total_rotational = 4 KE_rotational = (3/2)mv^2

The total kinetic energy of the car is:

KE_total = KE_translational + KE_total_rotational = (5/2)mv^2

So the fraction of the total kinetic energy of the car that is due to the rotation of the wheels about their axles is:

KE_total_rotational / KE_total = (3/5) = 0.6

Therefore, 60% of the car's total kinetic energy is due to the rotation of the wheels about their axles.

The pressure of the butane gas sample at 120.0 mL can be determined by using the ideal gas law equation, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.

To find the pressure of the butane gas sample at 120.0 mL, we need additional information such as the number of moles and the temperature of the gas. Once we have these values, we can use the ideal gas law equation, PV = nRT, to calculate the pressure.

1. Determine the values: Gather the known values for the problem, such as the volume (V = 120.0 mL) and any other given information, such as the number of moles (n) and the temperature (T).

2. Convert the volume: If necessary, convert the volume to the appropriate unit for the ideal gas law equation. The ideal gas law typically requires volume to be in liters, so if the given volume is in milliliters, divide it by 1000 to convert to liters.

3. Plug in the values: Substitute the known values into the ideal gas law equation, PV = nRT. Make sure to use consistent units for all the variables.

4. Solve for pressure: Rearrange the equation to solve for pressure (P). Divide both sides of the equation by the volume (V) to isolate pressure: P = (nRT) / V.

5. Calculate the pressure: Substitute the known values into the equation and perform the necessary calculations to find the pressure of the butane gas sample at 120.0 mL.
