A68 g sample of copper is at 20â¦c. if 1918 j of energy are added to the copper, what is its final temperature? assume the specific heat of copper is 387 j/kg â·â¦ c. answer in units of â¦c.

Final temperature of the sample is 92.88 degrees Celsius.

Explanation:

It is given that,

Mass of the sample of copper, m = 68 g = 0.068 kg

Initial temperature,

Energy added to the copper, Q = 1918 J

Specific heat of the copper,

We need to find the final temperature of the copper sample. The heat added is given by :

, T₂ is the final temperature

So, the final temperature of the copper sample is 92.88 degrees Celsius. Hence, this is the required solution.

we need answer choices

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
