The mass of the disk is 1.96 kg.

To find the mass of the disk, we can use the formula for torque (τ) and the formula for the moment of inertia (I) of a solid disk.
The torque formula is:
τ = F * r
where F is the applied force (50 N) and r is the radius (0.14 m).
The moment of inertia for a solid disk is:
I = (1/2) * m * r²
where m is the mass of the disk and r is the radius.
The angular acceleration (α) is related to torque and moment of inertia by:
τ = I * α
Substituting the formulas and the given values, we have:
50 * 0.14 = (1/2) * m * (0.14)² * 140
Solving for m, we get:
m = 1.96 kg

Summary: When a force of 50 N is applied tangentially to a solid disk of radius 0.14 m with a constant angular acceleration of 140 rad/s², the mass of the disk is 1.96 kg.

When two objects collide inelastically, it means that they stick together and move as a single unit after the collision. In such a scenario, the kinetic energy of the system decreases during the collision. This is because some energy is lost to deformation or other non-conservative forces like friction.

Therefore, the total kinetic energy of the system after the collision is less than the total kinetic energy before the collision. However, the momentum of the system is conserved during the collision. Momentum is a vector quantity that is the product of mass and velocity. The law of conservation of momentum states that the total momentum of a system remains constant if no external forces act on it. Therefore, the total momentum of the system before and after the collision will be the same.
To summarize, when two objects collide inelastically, the kinetic energy of the system decreases, but the momentum of the system remains conserved.

A fish that would stretch the spring by 0.2 meters has a weight of 2 N. Note that 2 N is equal to 0.2 kg

To determine the weight of a fish that would stretch a spring by a certain amount, we need to know the spring constant of the spring and the amount by which it is stretched.

The spring constant, denoted by k, represents the amount of force required to stretch the spring by a certain amount. It is typically measured in units of force per unit of distance, such as Newtons per meter (N/m).

Let's assume that the spring constant of the spring is k = 10 N/m, and it stretches by Δx = 0.2 meters when a fish is attached to it.

The force required to stretch the spring by Δx can be calculated using Hooke's law, which states that the force required to stretch a spring is proportional to the amount of stretch. Mathematically, this can be expressed as:

F = kΔx

where F is the force required, k is the spring constant, and Δx is the amount by which the spring is stretched.

Substituting the values we have, we get:

F = 10 N/m × 0.2 m

F = 2 N

Therefore, a fish that would stretch the spring by 0.2 meters has a weight of 2 N. Note that 2 N is approximately equal to 0.2 kg, since 1 N is equivalent to 0.1 kg. So the weight of the fish is approximately 0.2 kg.

we can use the law of conservation of momentum, which states that the total momentum of a system remains constant if there are no external forces acting on it.

Let's denote the mass of each car as m, and let the initial velocity of each car be v. The total initial momentum of the system is then:

p_initial = mv + m(-v) = 0

This is because the two cars are traveling in opposite directions at equal speeds.

After the collision, the two cars stick together, so they move as one object with a mass of 2m. Let's denote the final velocity of this object as v_f. The final momentum of the system is then:

p_final = (2m)*v_f

By the law of conservation of momentum, we know that p_initial = p_final. Therefore:

0 = (2m)*v_f

Solving for v_f, we get:

v_f = 0

This means that the final velocity of the two cars after the collision is zero. In other words, they come to a complete stop. This result makes sense intuitively, as the two cars have equal masses and speeds in opposite directions, so their momenta cancel out completely when they collide and stick together.

The impulse given to the nail by the hammer is 7.56 Ns

The impulse-momentum theorem relates the change in momentum of an object to the impulse applied to it. The impulse is equal to the force applied to an object multiplied by the time interval over which the force is applied:

Impulse = Force x Time

Momentum = mass x velocity

When the hammer strikes the nail, it imparts a force to the nail. This force causes the velocity of the nail to change, and the hammer comes to rest.

Change in Momentum = Final Momentum - Initial Momentum = -Initial Momentum

The initial momentum of the hammer can be calculated as:

Initial Momentum = mass x velocity = 15 kg x 5.0 m/s = 75 kg m/s

The time interval over which the force is applied is given as 5.7 ms, or 5.7 x[tex]10^{-3}[/tex] s. Therefore, the average force applied to the nail can be calculated as:

Average Force = Impulse / Time

We can rearrange this equation to solve for the impulse:

Impulse = Average Force x Time

Average Force = mass x average acceleration = 15 kg x (-Initial Velocity / Time)

Substituting the given values, we get:

Average Force = 15 kg x (-5.0 m/s / (5.7 x [tex]10^{-3}[/tex]s)) = -1.32 x [tex]10^6[/tex] N

Jupiter is not a solid body which means that its dynamic atmosphere rotates differently, taking five minutes longer than the equatorial atmosphere.

Jupiter is a gas giant and therefore does not have a solid surface like Earth. Instead, it is made up of layers of gas and liquid that become increasingly dense towards the center. The atmosphere of Jupiter is the outermost layer of gas and is composed mostly of hydrogen and helium, with small amounts of other gases such as methane, ammonia, and water vapor. Due to its size and rapid rotation, the atmosphere of Jupiter is divided into several distinct bands that run parallel to its equator.

Jupiter's atmosphere rotates differentially, meaning that different parts of the atmosphere rotate at different speeds. The equatorial regions of the atmosphere rotate the fastest, taking just under 10 hours to complete one rotation, while the polar regions rotate much more slowly, taking over 14 hours to complete one rotation. This creates an effect known as "zonal winds," where the different bands of the atmosphere move at different speeds, creating distinct patterns of cloud formations and weather systems.

Interestingly, the atmosphere of Jupiter also exhibits a phenomenon known as "retrograde motion," where some of the cloud bands move in the opposite direction to the planet's overall rotation. This is thought to be caused by eddies and vortices within the atmosphere, which can push cloud bands in different directions.

γ is the Lorentz factor, m is the rest mass of the particle, and c is the speed of light.

First, let's find the Lorentz factor for each particle. The Lorentz factor is given by:

γ = 1 / √(1 - v² / c²)

where v is the velocity of the particle.

For the electron and positron in this problem, v = 0.500c, so we have:

γ = 1 / √(1 - (0.500c)² / c²) = 1.1547

Next, let's find the rest mass of each particle. The rest mass of the electron is 9.10938356 × 10⁻³¹ kg, and the rest mass of the positron is the same.

Now we can use the formula for kinetic energy to find the energy of each particle. Plugging in the values we have:

Here, d is the spacing slit, sinθ is the sine of the angle between the central maximum and the m-th minimum, m is the minimum order (10 in this case), and λ is the wavelength of the light (515 nm, or 5.15 x 10⁻⁷ m).

The angle θ can be found using the small-angle approximation:

sinθ ≈ tanθ ≈ y/L where y is the distance between the central maximum and the m-th minimum (0.00776 m), and L is the distance between the slits and the screen (2.00 m). sinθ ≈ 0.00776 m / 2.00 m ≈ 0.00388

Now, we can solve for the slit spacing d: d ≈ [(10 + 1/2) * 5.15 x 10⁻⁷ m] / 0.00388 ≈ 1.45 x 10⁻⁶ m
