A space station has a large ring-like component that rotates to simulate gravity for the crew. This ring has a mass M = 2.1×10^5 kg

and a radius of R= 86.0 m and can be modeled as a thin hoop. Before spinning up the ring section, crew members Dave and Frank

dock their ships, each with mass m= 3.5×10^4 kg on two docking ports located on opposite sides of the center of the ring. The docking

ports are located r = 31.0 m from the center of the ring. When the station’s computer begins to spin up the ring it has to spin both the

ring and the ships. The ships can be treated as point particles. Two identical thrusters on the edge of the ring are used to spin up the

ring with a constant angular acceleration. The ring-ship system takes 3 hours to reach the angular speed at which it simulates Earth’s

gravity for the crew on the edge of the ring. What constant force must each of the two thrusters apply to reach this rotational speed?

A space station is located in a gravity-free region of space. It consists of a large diameter, hollow thin-walled cylinder which is rotating freely about its axis. It is spinning at a speed such that the apparent gravity on the inner surface is the same as that on earth. The cylinder is of radius r and mass M. (a) What is the minimum total work which had to be done to get the cylinder spinning up to speed. (b) Radial...

A space station is approximately a ring of radius,R, and mass m, which rotates about its symmetry axis with angular velocity,~ω=ω0ˆe3. A meteor is traveling with momentum,~p, that is parallel to the original ˆe3, and strikes the space station at a point on the rim,transferring the entire momentum to the space station (an inelastic collision where the meteor sticks to the space station). Further, though the meteor has significant momentum,it is of very small mass so that the moment of...

Is there gravity in space? Explain why? If an astronaut leaves his air-filled space station and takes his guitar out into space on a spacewalk, another astronaut will not be able to hear the sound guitar as he plays it. Why? Moon's radius distance from the centre of the Earth is given by ‘R’. If this radius is increased to 1.5 times ‘R’, how would this change affect the magnitude of gravitational force of the Earth on the Moon? How...

Is the following situation possible? A space station shaped like a giant wheel has a radius of r = 100 m and a moment of inertia of 5e8 kg m2. A crew of 150 people of average mass 60 kg is living on the rim, and the station's rotation causes the crew to experience an apparent free-fall acceleration of g. A research technician is assigned to perform an experiment in which a ball is dropped at the rim of the...

Your spaceship has docked at a space station above Mars. The temperature inside the space station is a carefully controlled 24 ∘C at a pressure of 735 mmHg . A balloon with a volume of 515 mL drifts into the airlock where the temperature is -83 ∘C and the pressure is 0.120 atm . What is the final volume, in milliliters, of the balloon if n remains constant and the balloon is very elastic?

A space station shaped like a giant wheel has a radius of 1.00 x 102 m and a moment of inertia of 5.00 x 108 kgm2. A crew of 150 lives on the rim, and the station is rotating so that the crew experiences an apparent acceleration of 1.0g. When 120 people move to the center of the station for a union meeting, the angular speed changes. What apparent acceleration is experienced by the mangers remaining at the rim? Assume...

A space station has an interior volume of 50m ^ 3 and at 25 °C it maintains an atmosphere of 10 ^ 5 Pa, which can be considered an ideal gas. If a 5mm diameter meteor makes a hole in the station wall, calculate: a) the number of molecules that leave space per second. b) the time in which the pressure would be reduced by 10% (for simplicity, suppose that the atmosphere contains only N2).

Black Hole has such a huge gravity, impacting space and matter in its vicinity the way that velocity reaches infinity, thus the time is close to zero, why or why not? include a short description of the Black Hole (how it forms, its characteristics after it forms and the definition of the Event Horizon. Perhaps you can also come up with a live example, which would help to explain the processes happening around the black hole.
