two volumes out of 174 (Engineering, Agriculture and Medicine)
one wonderful day Yi Zhang. (19 points)
Linger with water Warcraft
die after falling from the sky days Yi Zhang, Li edge of the cliff (see Figure 1-1). We all know that this is not unchanging, and is wonderful for this phenomenon, there are two assumptions: 1, Yi Zhang Since the days of strong spiritual power, in the bottom of the rod has an aura, can be equivalent to the density p dark matter. 2, due to a strong spiritual power, stick around a fixed rod covered with the infuriating, is equivalent to connecting rod mass in the heart of the eight spring, spring symmetrical distribution, which consists of the vertical plane and the rod, the same stiffness as k. Known: the rod length L, mass M, the center of mass at the top L / 3 Office, the vertical set. Existing problems are as follows:
(1) scenario 1 Aura was hemispherical with radius R, the distribution center of the sphere at the end of the rod, the ball down the crown, a round face with the stick vertical. Discuss to what extent p Yi Zhang in a stable equilibrium when the day
(2) Suppose 2 days Yi Zhang find the cycle time for small vibration T
Second, the fall of the town of demon sword. (27 points)
weight in the new building and Erigeron Once upon a duel. They finally tried my best to opposite sides of a hit after the bounce (see Figure 2-1), the town dropped the sword demon world (Figure 2-2). Re-building the quality of the known M1, Erigeron weight M2, the quality of the town of demon sword m (M2>> m), both at the same speed v0 separate after the collision, re-building the speed v1, Erigeron speed v2, the collision loss of energy E. Let the town square after monster throws the sword to the touch, and around its center of mass to rotate at constant angular speed w, in the mid-point of its center of mass. (The angular momentum caused by the angle of deviation from Erigeron negligible, that the collision occurred in a straight line) demon sword town of Shushan the stones need to be inserted into the momentum P, Shushan altitude h, excluding air resistance. Find:
(1) to make demon sword into the ground in the town, Once upon a minimum altitude of the new H
(2) Once upon this height corresponds to a new level of distance from the Shushan S
(3) If directly above the freedom of the town were drawn from the demon sword (not rotating),
gucci watches, find the minimum height of the L (1,2 Once upon a small problem that the new office as the acceleration of gravity and ground g, 3 small questions to the town demon sword as objects.)
III, heavy floor seal Suoyao Ta. (26 points)
heavy floor cleared magic seal Suoyao Ta, Suoyao Ta volume V, the same day as the atmospheric pressure P, air temperature T. Free hip re-building leaps, the volume of air equal to Suoyao Ta cemented an infuriating (This infuriating shares can be considered as ideal gas), re-cemented floor, the original volume of gas 1 / n, the temperature change ( Figure 3-1). Then change the first control volume, the infuriating double pressure; unchanged in the control pressure, the volume becomes 16 times, and finally infuriating thrown Suoyao Ta (Figure 3-2), all to restore calm. Let infuriating the release of the original state restored the magic to just repair Suoyao Ta, regardless of the heat exchange with the outside world and throw energy. Requirements:
(1) re-release the magic of building (energy) W
(2) spiritual power needed to repair Suoyao Ta (energy) Q
(3) the efficiency of this cycle n
(4) the efficiency of re-building repair Suoyao Ta k
four or five spirits the circle. (26 points)
Suoyao Ta Wu Ling top the circle strong, in fact, is an invisible spirit Conductor five balls (the original is not charged) in the horizontal section through center of the sphere. Endemic in the circle on the water and fire Wuling mine is also five small round ball over the cross section center of the sphere. This is a big ball of five small balls of the five cavities,
cheap gucci shoes, filled the middle of the corresponding attribute spiritual power. Big ball of known radius R, the ball radius r, from the five spiritual center of the circle the circle center R / 2, big round in a small round heart to heart connection from the heart of the small round r / 2 处 were fixed with electricity mine water q q q q Fire q soil line wind is very small conductor (which can be regarded as a point charge), all of the spiritual power and focus on these charges. Promise House in Shushan the spiritual power of the circle is equivalent to power for the Q of the point charge, that it is the circle with the top five spirits coplanar, the distance to the center of the sphere 4R, together with the potential energy between them maintains Shushan The stability and interest-bearing. Liao is on fire pulse to be opened up, q spiritual fire to the center of the circle of fire. Nangong Huang a pedestrian had to artificial vein open up the remaining places. After they get through to clock set, the property is discharged. When all were released after the charge can be reset (so-called friend to everybody.)
(1) When the fire when the clock has just opened up, q value of the spiritual power of fire (electrical potential)
(2) to all get through until you reset the clock before the spiritual power of the surface (charge distribution) of the change? At this point the value of q spiritual power of fire (electrical potential) is how much?
V., Xie Jianxian Swords (25 points)
Xiejian Xian Jian Zhong after winning two swords swords swords furnace starts ionizing the air to form a gradual increase in the magnetic field. Xie Jianxian evil body is a provider of energy supply, and two swords connected to form a loop. Symmetrically located two swords were raised in the vertical plane, Xie Jianxian arms with this plane, the loop is the arm length L of the diamond, and the town of demon sword Shadowbane angle of 60 degrees (this is my own vision screen). Xie Jianxian evil force is provided by E, the left hand bit positive power supply, internal resistance r. Uniform magnetic field increased, B = b + kt, k is a known constant, the direction of the level of point Xiejian Xian. Let t = 0 moment of swords, two swords is no force between the role of resistance each for R, and ignore the current around the magnetic field. When the issue of evil from the two swords will have reached the U, will be excited and produce evil sword (see Figure 5-1). Magnetic energy emitted is not evil, and asked when the cast evil sword Xie Jianxian A and the work done and requested the arms export Xie Jianxian the force used by their functional relationship with respect to time.
six principles Hokyo Dong Ming (23 points)
According to Dong Ming Hokyo
demon, its principles are as follows: its outer surface is convex, the distance of the monster in the mirror behind the image, apply a layer of the back of the demon water to form solid crystals, can the formation of virtual monsters like the sky. Know this principle, we not only can make magic mirror, you can also make glasses, etc., as the demon. Is to give you enough refractive index n = 1.57 for glass, plastic, long-barreled, there is a certain amount of monster lens. Suppose light is not on the screen of the demon imaging lens can be accessible through, you make a demon according to Kepler Galileo telescope and a telescope according to the demon, you can see very distant monster. Two telescopes were obtained in the lens diameter and focal length, and the distance, the combination approach. And draw the diagram of optical imaging.
seven, came and went without a trace of the re-building (28 points)
Zi Xuan,
gucci shoes, when the danger
, the Eye of the issue to the re-building the light frequency 100Hz frequency signal, re-building need to arrive within 10 seconds, purple Xuan side. Signal is received immediately after the re-building rate of 0.8C to the human world in time, just to save the next purple Xuan. (C is the speed of light in vacuum, ignoring the process of acceleration and deceleration) Find:
(1) the magic of two people from the community
(2) re-building think they only arrived at the amount of time to
(3) the number of re-building optical frequency received signal
(4) Purple Suoyao Ta Xuan want to seal, the seal of the former Eye of t seconds, a signal to the re-building. V-speed re-building to come, please discuss the outcome and non-violet purple Xuan Xuan finale, v and t satisfy the relations
Linear Mode
