A cylindrical space station of radius R and length L has a density that varies with distance from its center:
a.) Evaluate the mass dM of an infinitesimally thick cylindrical shell of radius r.
b.) Calculate the total mass M of the entire space station.
According to legend, to determine whether the king's crown was made of pure gold, Archimedes measured the crown's volume by find out how much water it displaced. The density of gold is 19.3g/cm^3. If the crown's mass was 6.00 * 10^2g, what volume ..
When placed 1.2 m apart, the force each exerts on the other is 12 N and is repulsive. What is the charge on each? What if the force were attractive.
What is phase change as the light is reflected from the top
Airtight box has a removable lid of area 1x10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.85x 10^5Pa. The inside of the box is completely evacuated. What is the magnitude of the force essen..
it accelerates with a constnat acceleration of 2.00 m/s^2 until its engines stop at an attitude of 200 m. the rocket continues move in free fall until its reaches the ground. Illustrate what is the total time the rocket is in the air?
Assume that ABC Firm has an optimal capital structure; comprised of debt, preferred stock and common equity. In this scenario, Firm currently has 48 percent debt, 4 percent preferred stock and 57 percent common equity in its capital structure.
Identical point charges of +2.4 ?C are fixed to diagonally opposite corners of a square. A third charge is then fixed at the center of the square, Find the sign and magnitude of the third charge
A car traveling 90km/h slows down at a constant 0.50 m/s^2 just by "letting up on the gas." Compute the distance it travels during the third second.
Light with a wavelength of 618 nm passes through a slit 7.52 wide and falls on a screen 1.88 m away. compute the linear distance on the screen from the central bright fringe to the first bright fringe above it.
An object has a kinetic energy of 313 J and the momentum of magnitude 24.1 kg·m/s. Find out the speed and the mass of the object.
A generator uses a coil that has 140 turns and a 0.50-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), find out the length of the..
Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 respectively and free. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do the angular frequencies of th..
