4) An astronaut standing at radius R1 on the inner ring of this space station moves a distance X1 along a circular arc as the station rotates.
A) Over what distance X2 does another astronaut at radius R2 on the outer ring move in the same time?
B) Over what angle, in degrees, did the space station rotate in this period, expressed in terms of R1 and X?

The space station is rotating to create artificial gravity. The speed of the inner ring is one half that of the outer ring. As an astronaut walks from the inner to the outer ring, what happens to her apparent weight? choice on of them? Her apparent weight becomes four times as great. Her apparent weight does not change. Her apparent weight becomes one-fourth as great. Her apparent weight becomes half as great.
4. (20 points) A space station is rotating to simulate gravity as the figure below indicates. An astronaut standing on the rim (ro = 2,150 m) of the outer ring experiences a simulated acceleration due to gravity on earth (9.80 m/s2). a) Calculate the period of rotation. b) What should be the radius ry of the inner ring so that it simulates the acceleration due to gravity (3.72 m/s2) on the surface of Mars?
The figure shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R2 is 0.6 m, its inner radius R1 is R2/2, its mass M is 7.4 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 6.5 rad/s with a cat of mass m = M/4 on its outer edge, at radius R2. By how much does the cat increase...
You have designed a space station that rotates on its axis in order to produce " artificial gravity." The space station has tree levels consisting of rings connected to spokes that rotate about a single axis as shown in the figure. The outer ring has a radius of 245 m. a. what must the angular velocity of the space station be to simulate the acceleration due to gravity on Earth's surface on the outer ring of the space station? b....
Determine the electric eld a distance z above the center of a ring with charge uniformly distributed between an inner radius R1 and an outer radius R2 (alternatively, you can describe this as a disk of radius R2 with a circular hole of radius R1). Do this two ways: by directly performing an integral over the surface of the ring and by superposition.

A coaxial cable consists of a fixed inner conductor with radius R1, which is surrounded by a concentric cylindrical tube with inner radius R2 and outer radius R3 (Figure 1). The conductors carry oppositely directed currents I0 of equal size, which are homogeneously distributed over their cross sections. Determine the magnetic field at a distance r from the axis for a) <R1, b) R1 <r <R2, c) R2 <r <R3 and d) R3 <r. (Show the appropriate ampere loop for...
need help with this question please FR2 R1 х A flat ring of inner radius R, and outer radius Ry has a uniform surface charge density of o. Find an expression for the electric field for points along the x-axis in two ways: (a) Calculate the potential first by treating the ring as a continuous charge distribution. Then find the electric field from the potential. (b) Calculate the electric field directly by treating the ring as a continuous charge distribution.
