Neutron stars consist only of neutrons and have unbelievably high densities. A typical mass and radius for a neutron star might be3.00 multiply.gif 1028 kg and 1.80 multiply.gif 103 m.
(a) Find the density of such a star.
kg/m3
(b) If a dime (V = 2.0 multiply.gif 10-7m3) were made from this material, how much would it weigh (in pounds)?
lb
A steel rod (? = 7860 kg/m3) has a length of 2.19 m. It is bolted at both ends between immobile supports. Initially there is no tension in the rod, because the rod just fits between the supports. Find the tension that develops when the rod loses 3..
The person in the middle weighs 190 N, and the tensions in each rope are 200-N. What is the weight of the staging.
What net torque must be applied to the wheel. How several meters would the molecule.
An organ pipe is 119 cm long. What are the fundamental and first three audible overtones if the pipe is closed at one end.
In a television tube, electrons originally at rest are accelerated by a uniform electric field of magnitude 4 times 105N/C during the first 5cm of the tube's length; after that they move at essentially constant velocity another 45cm before hitting..
An electron acquires 100fJ of kinetic energy when it is accelerated between two paralle lplates placed at a distance of 1mm
Suppose the river is flowing east at 3 m/s and the boat is traveling south at 4 m/s with respect to the river, Find the speed and direction of the boat relative to Earth
A 6 ornament is hanging by a 1.30 wire when it is suddenly hit by a 3.00 missile travelling horizontally at 10.0. The missile embeds itself in the ornament throughout the collision.
Calculate the time the microgel would require to recover to 99% of its initial height after the stress is removed. Determine the potential barrier for the molecule aggregation?
A 1128 kg car and a 2210 kg pickup truck approach a curve on the expressway that has a radius of 272 m. A) At what angle should the highway engineer bank this curve so that vehicles traveling at 72.9 can safely round it regardless of the condition..
