Want this question answered?
A pebble thrown in water creates concentric, expanding circular waves.
pebble has volume so water rises equal to volume of pebble
because a pebble is denser than water thus making it sink oil is not denser than water.
The pebble is heavier than water so it sinks. The wood isn't heavier than water so it floats.
put some water in a measuring cylinder, take the reading and then place the pebble in the water and take over the reading.Then you minus the two values to get the volume of the pebble\rock
Theme
First put water in measuring cylinder and note the volume of water. Next, put the pebble in it.
drop a pebble in the water or tap a puddle
All these actions produce waves. Musical instruments produce sounds waves in air. Dropping a pebble in water produces waves on the surface of the water.
An ammount of water spills out, exactly equal to the volume of the stone.
Coal is burned to produce heat, which then is transferred to water/steam, which produces mechanical power in the steam turbine, which produces electrical power from the generator
