where would you expect the atmospheric pressure to be greater: at the top of a mountain or on a beach?

The new angular speed when the man walks to a point 0m from the center is ω = 0.369 rev/s.

The definition of angular speed is the rate at which angular displacement changes, and it is expressed as,

ω=θ/t

where t is the period of time, is the angular speed, and ω is the angular displacement.

Radian per second is used to measure angular speed. Both angular velocity and angular speed are represented using the same formula.

Now for the given question,

Since there is no external torque, angular momentum of the system is conserved. Then, the angular momentum when the man is at x = 1.6 m, it is equal to that of x = 0 m.

[tex]L_1=L_2\\I_1ω_1=I_1ω_2[/tex]

where I is the moment of inertia of the system. Here we consider the merry-go-round which is a solid cylinder and the man which can be regarded as a point object.

Total moment of inertia in first case is

[tex]I_1=I_{cylinder}+ I_{man}= 1/2 m_{cylinder}R^2_{cylinder}+m_{man}d^2\\ = 1/2 (72)(1.6)^2+(97)(1.6)^2=340.48[/tex]

moment of inertia in second case is

[tex]I_2=1/2 m_{cylinder}R^2_{cylinder}+ m_{man}(0)\\=1/2(72)(1.6)^2=92.16[/tex]

In the second case, the man shows no contribution to the moment of inertia of the system, since he stands on the center.

Finally,

[tex]I_1ω_1=I_2ω_2\\(340.48)(0.1)=(92.16)ω_2\\ω_2=0.369 rev/sec.[/tex]

The metre, a measure of length denoted by the sign m, is the fundamental unit of force. The symbol for the kilogramme is a unit of mass.

In mechanics, force is any action that tends to maintain or alter a body's motion or distort it. The concept of force is frequently explained in terms of Isaac Newton's three laws of motion, as stated in his Principia Mathematica (1687). A body that is at rest or moving at a uniform rate in a straight line will remain in that state until some force is applied to it, according to Newton's first principle. According to the second law, when an external force acts on a body, it causes the body to accelerate (change in velocity) in the direction of the force.

The required maximum charge that the capacitor can have after the dielectric is inserted Q ≈ 1.98 x 10^-8 C

The capacitance of a parallel-plate capacitor is given by:

C = ε * ε0 * A / d

where

C is the capacitance (in Farads)

ε is the dielectric constant of the material between the plates

ε0 is the vacuum permittivity (8.854 x 10^-12 C^2/Nm^2)

A is the plate area (in m^2)

d is the plate spacing (in meters)

The maximum charge that can be stored in a capacitor without exceeding a given voltage V is given by:

Q = C * V

where Q is the charge (in Coulombs).

So, first we need to convert the plate area and plate spacing to SI units:

A = 10.0 cm^2 = 10.0 x 10^-4 m^2

d = 2.00 mm = 2.00 x 10^-3 m

Next, we can find the capacitance:

C = ε * ε0 * A / d

C = 3.00 * 8.854 x 10^-12 * 10.0 x 10^-4 / 2.00 x 10^-3

C ≈ 1.32 x 10^-10 F

Finally, we can find the maximum charge:

Q = C * V

Q = 1.32 x 10^-10 * 150.0

Q ≈ 1.98 x 10^-8 C

So, the maximum charge that the capacitor can have after the dielectric is inserted is approximately 1.98 x 10^-8 Coulombs.]

Prediction of unknown quantities: Dimensional analysis can be used to predict unknown physical quantities by using only the dimensional information of known quantities.

Unit conversion: Dimensional analysis can be used to convert units of physical quantities from one system to another.

Detection of errors: Dimensional analysis helps in detecting errors in mathematical expressions, as the dimensions of the different terms in an equation must match for the equation to be physically meaningful.

Demerits of Dimensional Equations:

Limited applicability: Dimensional analysis is only applicable to problems where the dimensions of the physical quantities involved are well-defined.

Assumptions required: Dimensional analysis requires certain assumptions to be made about the physical system being studied, and these assumptions may not always be valid.

Approximations involved: Dimensional analysis often involves approximations and simplifications, which can lead to errors in the final results.

Limitations in complex systems: Dimensional analysis can be difficult to apply in complex systems, where multiple physical phenomena are interacting and where the dimensions of the physical quantities involved are not well-defined.

A business jet of mass 36000 kg takes off when the thrust for each of two engines is 22000 N .its acceleration is 1.22 m/s^2.

The acceleration (a) can be calculated as follows:

a = (F_net) / m

Where F_net is the net force acting on the jet and m is its mass.

The net force can be calculated as the sum of the thrusts produced by each engine:

F_net = 2 * 22000 N = 44000 N

Finally, substituting the values of F_net and m into the equation above:

a = 44000 N / 36000 kg = 1.22 m/s^2

Thrust is a type of force that propels an object in a specific direction. It is the push or pull that moves an aircraft, a rocket, or any other type of vehicle through the air or through space. Thrust is created by the action of a engine or motor, which generates energy that is then transformed into movement. This movement can take various forms, such as the spinning of a fan, the burning of fuel in a combustion engine, or the explosion of a rocket.

Thrust is an essential component of flight, as it provides the energy needed to overcome the forces of gravity, air resistance, and friction.
