i think that what you are doing wrong is that if you want to have down as possitive and up as negative then u have to start out with upwards velocity being negative as well so that
-15.68(6) + 1/2(9.8)(6^2) = 82.32 , and you are correct you can chosse your own frame of reference but you...
The problem clearly asked for the kinectic energy " immediatly after the spring is relesed " . which means that we are not talking about any acceleration process. The ball with higher mass has a higher inertia ,it resist the "push" from the string with a greater force , from this follows that...
well , i think that this cannot be the case here. If you think about the objects as two fallen objects in vacuum ( as the surface is frictionless ) , the force acting on them is the same , gravitational pull ( anloguos to the energy given from the spring ) . The way you put it, it seems to...
Im just saying that this is the only way the answer makes sence.
besides the way i understand it the conservation rule of mommentum applies when two objects collide , but here there is a third object , the spring , that is resposible for the eenergy provided.
( i just resently got aquinted...
i would say that they mean that beacuse of the frictionless surface both gain the same velocity. if they both have the same velocity but different mass , the one with the higher mass will have more kinectic energy.
and the answer 125 sounds then logical. if the velocity is a constant then the...
Well , all the functions of life are basically just for contering entropy. therefore we die when we no longer can conter entropy . when the life function no longer work properly it`s then that the entropy "takes " over and the entropy equilibrium is reached
weell , damage to the body can...
dead is the entropy equilibrium , the point of maximum entropy . this can only be reached when the organism is no longer able to "clean " itself . i agree with you that it can be regarded as the cause of aging , because aging will eventually lead to death. as aging is the degradation of the...
entropy is the particle`s tendency to go from order to diorder. Entropy is directly conected with kinectic energy. a particel at the absolute zero will have lost its tendency to go from order to disorder , because it can't move any more , in the same way the higher the temperature is the more...
the process where the intermolecular force are being broken , and loosen up is measused in something other than specific heat capacity , it is called latent heat. during these process, melting/evaporating, the energy given is not used to increase temperature but to break or loosen the bonds...
but the w boson is supposed to have a mass 100 times greater than the proton ? , how can this amount of mass be created , is this why the electron needs to have a lot of kinectic energy ?
and how can the change of the "flavor" of the quark occur ? do you need to have a w boson to do so to...

the conclusion is that the enregy given to liquid water is used to other things that just "rising" the temperature.
