The tallest Ferris wheel in the world is located in Singapore. Standing 42 stories high and holding as many as 780 passengers, the Ferris wheel has a diameter of 150m and takes approximately 30 minutes to make a full circle. Determine the speed of the riders (in m/s) on the Singapore Flyer.
Answer:
The speed of the riders on the Singapore Flyer is approximately 0.262 m/s
Explanation:
The dimensions of the tallest Ferris wheel in the world are;
The diameter of the Ferris wheel, D = 150 m
The tine it takes the Ferris wheel to make a full circle, T = 30 minutes = 30 min × 60 s/min = 1,800 seconds
The angular velocity of the Ferris wheel, ω = 2·π/T
The linear velocity of the Ferris wheel, v = r·ω = The speed of the riders
Where;
r = The radius of the Ferris wheel = D/2
D = 150 m
∴ r = 150 m/2 = 75 m
∴ v = r·2·π/T
∴ v = 75 m × 2 × π/(1,800 s) ≈ 0.262 m/s
The speed of the riders on the Singapore Flyer, v ≈ 0.262 m/s

what is the most dense type of stars?
Answer:
A neutron star is the most intensely dense object in all the universe. Of course, the argument can be made that a black hole is the most dense, but considering that a black hole is technically beyond the event horizon, it is neutron stars that get the top spot for the being the ‘most dense’.

Find the average acceleration of a northbound subway train that slows down from 12 m/s to 9.6 m/s in 0.8 seconds.
Answer:
[tex]a=-3\ m/s^2[/tex]
Explanation:
Given that,
Initial speed of a train, u = 12 m/s
Final speed of a train, v = 9.6 m/s
Time taken, t = 0.8 s
We need to find the average acceleration of the train. We know that the rate of change of velocity is equal to acceleration. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{9.6-12}{0.8}\\\\a=-3\ m/s^2[/tex]
So, the average acceleration of the train is equal to [tex]-3\ m/s^2[/tex].

An object travels a distance d with acceleration a over a period of time t according to the equation: d = at² After 2.3 seconds with an acceleration of 9.8 m/s2, how far does an object travel (rounding the answer to two significant figures)?
Answer:
A 26m
Explanation:
firstly the answer will not be part c as distance unit will be meters (m)
next, substitute the values of a and t as shown
[tex]\frac{1}{2} (9.8)(2.3)^2 = 25.921[/tex]
the answer rounded off to 2 significant figures will be hence 26m

A man digs a hole in the soil next to a bush. How does the shovel make work easier for the man digging the hole? Check all that apply. The shovel changes the direction of the force the man applies. The man can apply less force. The man has to apply more force. The force applied by the end of the shovel decreases. The force applied by the end of the shovel increases.
Answer:
Following are the solution to the given points:
Explanation:
The shovel shifts the course of the man's force.
Man can use less power.
The strength at the end of the shovel is growing.
Its shovel is a tool that is used to excavate and transfer its large particles. This streamlines the job for all the men to find the pit.
Its machines modify their method that uses force. Its man must therefore use less force to lift the bulk material.
Answer:
The shovel changes the direction of the force the man applies.
The man can apply less force.
The force applied by the end of the shovel increases.

A window cleaner has a weight of 839.86 N. The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m. How much potential energy does the window cleaner have?
Answer:
E = 10078.32 J
Explanation:
Given that,
The weight of a window cleaner, F = 839.86 N
The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.
We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :
E = mgh
Put values,
E = 839.86 × 12
E = 10078.32 J
So, the window cleaner will have 10078.32 J of potential energy.
Un cuerpo cuya masa es de 20 kg se lleva primero a la luna y luego a marte. Teniendo en cuenta el factor que liga masa y peso en marte es de 3,8 N/Kg
Answer:
W = 76 N
Explanation:
In this exercise you are asked to find the weight of the body.
Mass is a quantity that is invariant, it measures the same everywhere, the weight depends on where it is measured, a simple way to find the weight of a body is
W = g m
where g is the constant of the place, in this case we have the weight of the body on Mars and its mass which is constant on Earth and on Mars
W = 3.8 20
W = 76 N
A sound wave is produced by a musical instrument for 0.40 second. If the frequency of the wave is 370 hertz, how many complete waves are produced in that time period? *

The number of waves produced by the musical instrument during the given time is 148 waves.
What is meant by frequency of a wave ?Frequency of a wave is defined as the number of oscillations completed by the wave in one second.
Here,
The frequency of the wave, f = 370 Hz
That means the wave completes 370 oscillations in 1 second. Or 370 waves are produced by the musical instrument in 1 second.
The time taken by the instrument to produce waves, t = 0.4 s
Therefore,
The number of waves produced by the musical instrument during this time is,
n = f x t
n = 370 x 0.4
n = 148
Hence,
The number of waves produced by the musical instrument during the given time is 148 waves.
