I think so because if it starts at a low temperature for that material, it should melt when you bring it up to that temperature.
C.energy
The law of conservation of energy says that energy can neither be created nor destroyed.
Answer:
Yes
Explanation:
In the International System of Units (SI), energy is measured in joules. One joule is equal to the work done by a one- newton force acting over a one- metre distance
When the sound wave returns to the machine, you can measure
how long it took to return.
(You may notice that it's working just like RADAR, which does the
same thing with radio waves instead of sound waves.)
Even if you know how long the sound took to get to the bottom and
return to the top, you can't DO anything with this information if you
don't know the SPEED of the sound through the water. Not only
the inventory of this machine, but anyone who uses it, has to know
the speed of the sound through water in order to use the round-trip
time to calculate the depth.
Answer:
The sun is the ultimate source of energy for all food chains. Through the process of photosynthesis, plants use light energy from the sun to make food energy. Energy flows, or is transferred through the system as one organism consumes another.
