Acopper rod is 0.450 m long. heat is added to the rod until it expands by 0.00130 m. how much did the temperature change? (unit=c)

170⁰C

Explanation:

α= ΔL/(lo×Δt)

arranging for Δt

Δt =ΔL/(lo×α)

here Δt is change in temperature, ΔL is change in length,lo is original length and is α coefficient of linear expansion and for copper its value is 17×10^-6

Δt =(0.00130)/(0.450×17×10^-6)

Δt=169.9⁰C

Δt= 170⁰C

as technology advances, new experiments often expose problems in accepted theories. c

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
