Answer:
The length of the wire is 83.2 m.
Explanation:
Given that,
Power of heater, P = 300 W
Voltage, V = 110 V
The resistivity of nichrome wire is,
The electric power of a wire is given by :
Area of cross section of the wire is :
Resistance of a material is given by :
So, the length of the wire is 83.2 m. Hence, this is the required solution.
Answer:
the total kinetic and potential energy of its particles
Explanation:
The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
That is because salt solutions contains Na+ and CI- ions When ions are present in the solution, these ions can move through the solution to carry an electric current. But sugar molecules DO NOT break down into ions when dissolved.
Creating new elements in order to study their properties is definitely pure research.
It has no earthly [known] application, since the elements don't even exist, whereas
for each of the other choices, you've stated the desired application as the reason
for the search.
