Answer:

85.8 m/s

Explanation:

We know that the length of the circular path, L the plane travels is

L = rθ where r = radius of path and θ = angle covered

Now,its speed , v = dL/dt = drθ/dt = rdθ/dt + θdr/dt

where dθ/dt = ω = angular speed = v'/r where v' = maximum speed of plane and r = radius of circular path

Now, from θ = θ₀ + ωt where θ₀ = 0 rad, ω = angular speed  and t = time,

θ = θ₀ + ωt = 0 + ωt = ωt

So, v = rdθ/dt + θdr/dt

v = rω + ωtdr/dt

v = (r + tdr/dt)ω

v = (r + tdr/dt)v'/r

v = v' + tv'/r(dr/dt)

v = v'[1 + t(dr/dt)/r]

Given that v' = 110 m/s, t = 33.0s, r = 120 m and dr/dt = rate at which line is shortened = -0.80 m/s (negative since it is decreasing)

So, v = 110 m/s[1 + 33.0 s(-0.80 m/s)/120 m]

v = 110 m/s[1 + 11.0 s(-0.80 m/s)/40 m]

v = 110 m/s[1 + 11.0 s(-0.02/s)]

v = 110 m/s[1 - 0.22]

v = 110 m/s(0.78)

v = 85.8 m/s

Answer:

Flow rate and velocity are related by Q=A¯v where A is the cross-sectional area of the flow and v is its average velocity.

The graph in which the block will travel with the greatest speed is the graph with the greatest displacement at given equal forces.

Based on the principle of work energy theorem, the work done in moving the block against the frictionless floor is equal to the kinetic energy.  

K.E = ¹/₂kx²

K.E = ¹/₂Fd

¹/₂mv² = ¹/₂Fd

mv² = Fd

v² = Fd/m

v = √ (Fd/m)

Thus, the graph in which the block will travel with the greatest speed is the graph with the greatest displacement at given equal forces.

Answer:

51.02m

Explanation:

KE = 1/2mv2

Where k.e = 250J

mass = 0.5 kg

g = 9.8 m/s2

250= 1/2×0.5×v^2

250= 0.5×0.5×v^2

250= 0.25v^2

v^2 = 250/0.25

v^2 = 1000

v =√1000

v = 31.62m/s

v^2= u^2-2gh........... (1)

Since the object will stop at it highest point, hence it final velocity there will be zero and since it is moving up against the gravity g= -9.8m/s^2. That was why the formula in equation 1 has a negative sign

From h = u^2/2g

Where v = 31.62m/s

g = 9.8m/s^2

H = (31.62m/s)^2/9.8×2

H= 1000/19.6

= 51.02m

Hence the height of it travelling will be

51.02m

To determine the work done on the elevator car, we can use the formula:

Work = Force x Distance x Cos(theta)

where the force is the tension in the cable, and theta is the angle between the direction of the force and the direction of motion (which is zero in this case since the elevator moves vertically).

Since the elevator is lifted at a constant speed, we know that the net force acting on it is zero. Therefore, the tension in the cable must equal the weight of the elevator plus the frictional force:

Tension = Weight + Frictional Force

Tension = (1400 kg)(9.8 m/s^2) + 1275 N

Tension = 13730 N

Using this tension value and the given distance of 36 m, we can calculate the work done on the elevator:

Work = (13730 N)(36 m)(Cos(0))

Work = 494280 J

Therefore, the work done on the elevator car to lift it 36 m is 494,280 J, assuming a constant frictional force of 1275 N.

The height of the image of a person formed by a plane mirror is equal to the height of the person.

The height of the image of a person formed by a plane mirror is equal to the height of the person itself. When an object, such as a person, is placed in front of a plane mirror, the mirror creates a virtual image that appears to be behind the mirror.

The virtual image has the same size as the object and is located at the same distance behind the mirror as the object is in front of it.

Since a plane mirror does not introduce any magnification or distortion, the height of the image will be identical to the height of the person. The mirror simply reflects the light rays in a way that creates the illusion of an image, maintaining the proportions and size of the object.

Therefore, the height of the image of a person formed by a plane mirror is equal to the height of the person.

The direction of the acceleration of the elevator is upward.

To determine the magnitude and direction of the acceleration of the elevator, we need to use Newton's second law of motion, which states that force equals mass times acceleration (F=ma).

The tension in the rope, measured to be 88 N, is the force acting on the object. Since the object has a mass of 10 kg, we can use F=ma to calculate the acceleration of the elevator.

88 N = 10 kg x a

a = 8.8 m/s^2

So the magnitude of the acceleration of the elevator is 8.8 m/s^2.

To determine the direction of the acceleration, we need to consider the direction of the forces acting on the object. In this case, the force of gravity is acting downward on the object, while the tension in the rope is acting upward. Since the tension in the rope is greater than the force of gravity, the net force on the object is upward.

In the context of amusement park rides where you are spun in a cylinder and pressed against the wall, it is not actually a "centrifugal force" that holds you against the wall, but rather the normal force exerted by the wall.

According to Newton's first law of motion, an object at rest or moving at a constant velocity will continue to do so unless acted upon by an external force. In this case, when you are inside the spinning cylinder, your body tends to move in a straight line due to inertia. However, the curved path of the cylinder exerts an inward force on your body, trying to pull you towards the center of rotation.

To counteract this inward force, the wall of the spinning cylinder exerts a normal force on your body, pushing you against the wall. This normal force acts perpendicular to the wall and is what holds you in place. It is important to note that the normal force is a reaction force to the inward force, not a separate force called "centrifugal force."

In summary, you are held against the wall of the spinning cylinder due to the normal force exerted by the wall, which counteracts the inward force resulting from your curved motion inside the cylinder.

Volume_submerged = (Density_mantle / Density_mountain) * Volume_exposed

Volume_submerged_meters = Volume_submerged / 1000000

Weight_submerged = Density_mantle * Volume_submerged_meters * g

Weight_submerged = Weight_exposed

Density_mantle * Volume_submerged_meters * g = Density_mountain * Volume_exposed * g

Volume_submerged_meters = (Density_mountain / Density_mantle) * Volume_exposed

Volume_submerged_meters = (3.2 g/cm^3 / 4.1 g/cm^3) * 4400 meters

Volume_submerged_meters = (0.7805) * 4400 meters

The three requirements needed to be recognized as a distinct air mass are as follows::

-1)Size

2)Uniform

3)Travel as a unit

The three requirements needed to be recognized as a distinct air mass are as follows:

Size: An air mass must be large enough to be considered a distinct entity and not simply a local fluctuation in the atmosphere. Generally, an air mass should have a horizontal extent of at least 1000 km or more.

Uniform properties: An air mass must have uniform horizontal properties such as temperature, humidity, and stability. This means that at any given altitude in the air mass, its physical characteristics must be relatively the same, with minimal variation.

Travel as a unit: An air mass must travel as a unit and be distinct from the other surrounding air masses. When it moves, it must retain its original characteristics and not be torn apart by differences in airflow. If an air mass undergoes significant mixing with other air masses, it may lose its distinct properties and no longer be considered a separate entity.

The kinetic energy of an ion released from rest and accelerated through a potential difference of 2.5 kV is 2500 eV.


Kinetic energy is the energy an object has due to its motion. When an ion is released from rest and accelerated through a potential difference, it gains kinetic energy. The amount of kinetic energy gained is equal to the potential difference multiplied by the charge of the ion.

Since the ion is released from rest, its initial kinetic energy is 0. The potential difference is 2.5 kV, or 2500 V. The charge of the ion is 1 e, or 1.6 x 10⁻¹⁹ C.

Therefore, the final kinetic energy of the ion is:
KE = qV
KE = (1.6 x 10⁻¹⁹ C)(2500 V)
KE = 4 x 10⁻¹⁶ J
KE = 2500 eV

        I_y = m (3r) ²

        I_y = 9 m r²

c) Regarding the z-axis.

We look for the distance.

         z =√x^2+y^2

         z = √ 1^2+3^2

We calculate the moment of interia  Iz = m (10r²)

        Iz = 10 m r²

In conclusion using the definition of moment of inertia we can look for the results of the moment of interia for each axis are:

  a) Iₓ = m r²

  b) I_y = 9 m r²
