= (18 x 10^-6 /°C)(0.125 m)(100° C - 200 °C)
= -0.00225 m
New length = L + ΔL
= 1.25 m + (-0.00225 m)
= 1.248

The potential energy of the skateboarder at the top of the ramp is
489.1 J.
<h3>Is kinetic energy always equal to potential energy?</h3>
The amount of kinetic energy change and the amount of potential energy change are equal in all physical processes that take place in closed systems. When the kinetic energy rises, the potential energy falls, and vice versa.
Potential energy is the stored energy in any object or system as a result of its position or component arrangement. However, external factors like air or height have no effect on it. The energy of a moving object or system is referred to as kinetic energy.
Potential energy = kinetic energy
Potential energy = 1/2mv²
Potential energy = 1/2 × 67×7.3
Potential energy = 489.1 J.

Answer:
a burning piece of converts Chemical energy into Heat(Thermal) and Light energy
I do not have a clue i need to answer so i can ask questions sorry
Answer:
resistance depends on length , cross sectional area , type of material and temperature
fuse is a safety device
Explanation:
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. ... The resistance of a conductor, or circuit element, generally increases with increasing temperature.
fuse is a safety device which is damaged when large amount of electricity pass through it and it does not damage any other component when electricity reach the fuse wire the fuse wire is very thin so if amount of electricity reach it burnt and and save the other component of house
yes water can conduct electricity
