A mechanical wave<span> is a </span>wave<span> that is an oscillation of </span>matter<span>, and therefore transfers energy through a </span>medium.[1]<span> While waves can move over long distances, the movement of the </span>medium of transmission<span>—the material—is limited. Therefore, oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia.</span>
Explanation:
Cold butter placed on hot corn melts because of convection. Butter placed on hot corn melts because it touches the hot corn. Most of the heat is transferred through conduction
Answer:
nope don't think so
Explanation:
the heat causes the molecules to move faster therefore expanding in watever it the air is in
Answer:
Part a)
%
Part b)
%
Explanation:
As we know that total power used in the room is given as
here we have
Part a)
Since power supply is at 110 Volt so the current obtained from this supply is given as
now resistance of transmission line
now power loss in line is given as
Now percentage loss is given as
%
Part b)
now same power must have been supplied from the supply station at 110 kV, so we have
now power loss in line is given as
Now percentage loss is given as
%
