One of the world's largest Ferris wheels, the Cosmo Clock 21 with a radius of 50.0 m is located in Yokohama City, Japan. Each of the sixty gondolas on the wheel takes 1.00 minute to complete one revolution when it is running at full speed. Note: Ignore gravitational effects. What is the centripetal acceleration of the gondola when the Ferris wheel is running at full speed
Answer:
a = 0.55 m / s²
Explanation:
The centripetal acceleration is given by the relation
a = v² / r
angular and linear velocities are related
v = w r
we substitute
a = w² r
In the exercise they indicate the angular velocity w = 1 rev/min, let's reduce to the SI system
w = 1 rev / min (2pi rad / 1rev) (1min / 60s) = 0.105 rad/ s
let's calculate
a = 0.105² 50.0
a = 0.55 m / s²

Standing and holding a barbell that has a mass of 100kg at a height of 2m involves being done on the barbell to maintain
the position.
Answer:
1960Joules
Explanation:
Since we are not told what too find, we can as well find the Gravitational Potential Energy.
GPE = mass * acceleration due to gravity * height
GPE = 100*9.8 * 2
GPE = 980*2
GPE = 1960Joules
Hence the gravitational potential Energy is 1960Joules

what are the conditions for a body to be at equilibrium
Answer:
Explanation:
Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium
What is the mass of a child in a wagon that has a velocity of 10 m/s and a Momentum of 30 KG* M/S

then : 30 = 10 × m and m = 30 ÷ 10 = 3 kg
I was playing goalie in a soccer league and made a save. The ball was traveling at 14 m/s and has a mass of 0.45 kg. How muck kinetic energy did the ball have when it hit me
Answer:
Kinetic energy = 44.1 J
Explanation:
Given:
Velocity of ball = 14 m/s
Mass of ball = 0.45 kg
Find:
Kinetic energy
Computation:
An item's kinetic energy is force it has as a result of its motion. It is the amount of work necessary to move a body of a known volume from rest to a specified velocity.
Ke = (1/2)(m)(v²)
Ke = (1/2)(0.45)(14²)
Ke = (1/2)(0.45)(196)
Kinetic energy = 44.1 J

A 1202-kg car is stopped at a stoplight. Inside, the car has three occupants. The two passengers have a mass of 75 kg each, while the driver has a mass of 105 kg. The driver steps on the gas pedal, and the car begins to accelerate at a rate of 2.5 m/s2 . What is the force that the engine is applying to the car?
Answer:
F = 63.25 N
Explanation:
a = 2.5 m / s ²
m = 25.3 kg
F =?
We calculate the force.
F = ma
F = (25.3 kg) (2.5m / s²)
F = 63.25 N
Solution.
F = 63.25 N
whar determines the direction of ocean currents
Answer:
The direction in which they rotate is determined by the hemisphere in which they are located. The main overall global wind patterns, the rotation of the Earth, and the shape of ocean basins are the three major factors that decide surface currents.
Oceanic factors are Tempature, salinity, density, pressure gradient and melting of ice. Atsmopheric factors are atsmopheric pressure, winds, rainfall, evaporation and insolation

If you use a lever to lift a boulder 0.25m, while applying 350 N on the lever which moves 1.5 m down on your side. What is the weight of the boulder? (F1d1 = F2d2) 87.5 N 131 N 525 N 2100 N
Answer:
2100 N
Explanation:
From the question,
Using the formula
F₁d₁ = F₂d₂..................... Equation 1
Where F₁ = Weight of the Boulder, d₁ = distance moved by the Boulder, F₂ = Force applied on the lever, d₂ = distance moved by the lever.
make F₁ the subject of the equation
F₁ = F₂d₂/d₁.................... Equation 2
Given: F₂ = 350 N, d₁ = 0.25 m, d₂ = 1.5 m
Substitute these values into equation 2
F₁ = 350(1.5)/0.25
F₁ = 2100 N

there is T__ as much voltage. This
produces twice the current
1.) True or False.
The two forces in an action-reaction pair are always equal in strength.
2.) True or False.
The two forces in an action-reaction pair act in the same direction.
3.) True or False.
Action-reaction force pairs act on the same object.
4.) True or False.
Action-reaction force pairs act simultaneously.
Answer:
Explanation:
According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted. 1.True 2.falues 3.true 4. not really sure on this one

Which best describes nuclear fusion?
A nucleus spontaneously splits and absorbs energy.
Two nuclei spontaneously combine and absorb energy.
A nucleus collides with a neutron and splits, releasing energy.
Nuclei combine to form a heavier nucleus, releasing energy.
Answer:
The statement that best describes nuclear fusion is;
Nuclei combine to form a heavier nucleus, releasing energy
Explanation:
In nuclear fusion, we have the reaction of the nuclei of two or more atoms coming together (combining) to form heavier elements and subatomic particles such as protons and neutrons accompanied by the release or absorption in energy depending on the difference between the mass of the reactants and the products
Some nuclear fusion reaction require an input of energy and such reactions are therefore not spontaneous
The best option is nuclei (two or more nuclei) combine to form a heavier nucleus, releasing energy.
Answer:
The answer is the last option or D
Explanation:
Nuclei combine to form a heavier nucleus, releasing energy.

Answer:
calculate the mass of mass A i the diagram .the frame joining the mass is massless
Explanation:
The mass of mass A the diagram .the frame joining the mass is massless.
What is Mass?The unique location in an object or system that can be used to describe how the system reacts to outside forces and torques is referred to as the "center of mass" or "center of gravity" in a uniform gravity field.
The idea of the center of mass is that it is the average of all the masses divided by the distances between them. With regard to the torques produced, that is comparable to balancing a seesaw around a pivot point in one plane.
Therefore, The mass of mass A the diagram .the frame joining the mass is massless.

The reason a penny thrown straight up inside a bus will come back to your hand is that you, the bus, the air inside the bus, and the penny are all moving at the same velocity.The law of inertia applies to both moving and nonmoving objects.
this is a true or false question help
Answer:
its false
Explanation:
since the penny is thrown straight up its not going to move forwad with you and the bus since it has no forces pushing on it. If the bus wasn't moving it would land back on your hand
What's a Blackhole ?
Answer:
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
