It is proposed that future space stations create an artificial gravity by rotating. Suppose a space station is constructed as a 1600-m-diameter cylinder that rotates about its axis. The inside surface is the deck of the space station.
What rotation period will provide "normal" gravity?
What is true of the net force when 3 or more forces are in a state of equilibrium, and If a force (F) make an angle (theta) with the x-axis, what are the formulas used to the x and y components of this force
Assuming that the disks form a circular parallel plate capacitor and the electron are initially at rest when they pass through the first disk. A) determine the acceleration that the electrons undergo and B) the speed of the electrons as they pass ..
A high-speed flywheel in a motor is spinning at 450 rpm when a power failure suddenly occurs. The flywheel has mass 37.0kg and diameter 71 cm. The power is off for 27.0s and during this time the flywheel slows due to friction in its axle bearings...
Two tiny conducting spheres are identical and carry charges of -18.2 ?C and +50.3 ?C, What is the magnitude of the force that each sphere experiences
When are the displacement, velocity, and acceleration equal to zero for the motion of a mass on a spring? A. at maximum displacement B. at minimum displacement C. at the equilibrium position D. at a displacement of 2x E.at a displacement of 1/3x.
An airplane starting from airport A flies 280 km east, then 365 km at 29.0° west of north, and then 130 km north to arrive finally at airport B.
A magnetic B field with strength 1 T passes through a metal square loop measuring 0.8 m on its side. If the B field is parallel to the loop's normal
A worker drops a wrench from the top of a tower 88.00 m tall. With what velocity does the wrench strike the ground? (Suppose the positive direction is upward.)
evaluate what value of the distance d should a driver locate his car if he wishes to stay on a circular path without depending on friction?
If it started falling from an upright position, what was the initial angular acceleration of the structure? suppose that the bottom did not slide across the floor and that it did not fall out of plane; that is, during the fall, the structure remained..
Two point charges Q1=+5.00 nC and Q2= -3.00 nC are separated by 35.0cm. (a) What is the electric potential at a point midway between the charges? (b) What is the potential energy of the pair of charges? What is the significance of the algebraic si..
Why is surface wind always directed at some angle across sea-level isobars toward lower pressure? Why is the surface wind directed across the sea-level isobars at a greater angle in Madison than over the middle of Lake Michigan.
