waves transfer matter, but not energy
Yes. Displacement is change in position. If you move through a distance so that your starting position is the same as your stopping position, your displacement, is zero.
Yes they do need particles to travel through!
because the surface area of the larger particles propels them faster which has a recipical effect on the water around the particles
A wave's ___________ is a measure of how far the particles in a medium move away from their normal rest position.
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
Yes. Displacement is change in position. If you move through a distance so that your starting position is the same as your stopping position, your displacement, is zero.
You must face towards the exit to get out. Once in that position, move towards the exit. Continue this to exit the cave.
suspension particles can be seen through a microscope
Yes they do need particles to travel through!
The order of symmetry of an object is the number of part-rotations that bring the object to a position that is identical to its starting position. Note that since all objects must return to their starting position if rotated through one whole circle (360 degrees), rotational symmetry of 1 is not counted.
Nope. Light particles (photons)are nowhere near energetic enough to do that. On the other hand, tiny super-high-energy particles called, "Neutrinos" from outside the Earth are right now passing through you, me, and the entire Earth. There are not many materials dense enough to stop Neutrinos!
Sound, unlike light, needs a medium through which to travel. Sound relies on vibrating molecules or particles. Sound can travel through air at about 3 km/s as it vibrates particles and then the neighbouring particles etc. but it can travel much faster through steel because the particles are much more tightly packed.In outer space there are not enough particles to vibrate, no neighbouring particles for the very few particles that are there. No particles means that there is no sound.
No. The individual particles of the medium wiggle back and forth, but stay in the same average position. It's the wiggle that travels from the source to the receiver, like the 'wave' through the grandstand.
You start at the origin and go down 4, forward one. Continue doing that. Then, go up 4, back 1 starting back at the origin. Continue doing that.
Liquid solids are the particles that come from liquid. This goes through a membrane.
because the surface area of the larger particles propels them faster which has a recipical effect on the water around the particles
