Susie hammers on a block of wood when she is 85 m from a large brick wall Each time she hits the block she hears an echo 0.5 s later With this info calculate the speed of sound?
85m/persecond No. For Susie to hear the echo, the sound has to travel 170 meters--85m to the wall, 85m back. The return hits her half a second after she hits the wood, so the hammer stroke has to travel to the wall in .25 second. 170 meters times two is 340 meters/second.

What will fall faster a 1 pound of sand or 1 pound of bricks?
The brick falls faster through the air than loose sand because each grain of sand has to overcome air resistance which is proportionally larger for the small particles.If you put both brick and sand into the same size box then they will fall at the same rate.

How fast does sound travel through brick?
Sound travels through brick at the speed of 3650 meters per second. Sound is a mechanical wave that can travel through many different types of media, such as water, cork, gold, and glass.
Where does sound travel faster wood or brick?
You mean which one does it travel faster in? It would be a brick because of how tightly packed the molecules in the brick are together. Wood, which is a lot more fragile that brick, does not allow sound to travel through it as fast.
On a cold day metal feels colder to touch than a brick why?
On a cold day, metal feels colder to the touch for 2 different reasons. The first reason has to do with specific heat. Specific heat is the amount of heat that has to be added to a substance to raise a certain amount of that substance to a certain temperature. This is relevant to the question because brick has a higher specific heat than most metals such as iron and steel. If a 1 pound brick and a 1 pound steel bar are placed in an oven, the steel will absorb the heat faster than the brick will. At the same time, if put outside on a cold day, that same steel bar will lose heat at a quicker pace than the brick will meaning the steel actually is colder. The second reason is much simpler and has to do with the texture of most metals vs the texture of a brick. If we use the steel bar example again, a steel bar is going to have a very smooth surface so when you touch it your skin is contacting the bar in more places. When you touch a brick, the brick has a gritty texture and the surface is uneven so the brick only contacts your skin at certain points. The more points at which your skin contacts a cold object, the more nerves send the sensation of cold to your brain and therefore the steel feels colder even if they are the same temperature.
