Adistributor of ball bearings sells packages of "remnant" ball bearings that contain a mixture of copper bearings and titanium bearingsâalong with bearings made of a proprietary alloy of several different metals. although the bearings all have the same diameter, 4.175 mm, the metals from which they are made all have different densities. the density of the proprietary alloy is 5.659 g/cm^3.packages of the remnant bearings are, on average, 30.4 percent copper bearings and 51.2 percent titanium bearings, the remainder being proprietary alloy. using the formula for the volume of a sphere, v = 4/5ïr^3, and the densities of the metals. determine the average mass of a ball bearing in one of the packages.

explanation:

i think option no d is the correct answer

it's filtration, but this is an assumption so my apologies if i got this

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
