A massless spring, with K=425 N/m, is hung vertically with the bottom end of the spring at position Y.i. A 3.50 kg mass is attached to the bottom of the spring and allowed to fall and oscillate. A) How far below Y.i does the mass fall before coming momentarily to rest and reve...
The planet Tralfamador is a planet of mass M and radius R, and very thin atmosphere (neglect air resistance). A magnetic rail gun has been mounted on the surface of Tralfamador at the North pole. A projectile of mass m is fired from the magnetic rail of gun with an unknown spe...
Some communication satellites are put into a circular geosynchronous orbit in which the satellite remains above a certain position on the earth's equator as it orbits. Such a satellite would always be in the same position in the sky as seen from the transmitting or receivi...
there is a 20% chance that it will snow on tuesday and a 50% chance that it will snow on Wednesday. what is the probabilty that it will snow on either day?
if the amount of radioactive iodine-123 in a sample decreases from .400g to .100g in 26.2 hours, what is the half-life of iodine-123
You can look them up in a chart. Try going to engineeringtoolbox website. They have a very useful chart of the specific heat of metals
Delta (triangle) E is the change in internal energy. E(final)-E(initial) 25-12= 13 = E(final) 13-25= -12kj= Delta (triangle)E
C'mon @cheers!! get some rest :) 5A is not (0,-1), or (0,1/sqrt(K)) or (0,-1/sqrt(N)) xD It must be something very close to it... I think the answer is translating the grover algorithm to a Bloch Sphere and see how it moves around the surface :) At least, that is what 5B,c...
wow! Strange behaviour @cheers xD Nevertheless good news for 5C :D Now, only 5A remains behind the Fortress of Solitude...
5A is not -1/sqrt(N) or any combinations with minus sign.
