Answer:
134.397 Joules
Explanation:
Using the formula:
E = C × m × Δθ (where E is Energy, C is specific heat capacity and Δθ is change in temperature)
So E = 0.45×5.45×(79.8-25)
So E = 134.397 Joules
It's B. 6.25
first divide 50/2
then divide 25/2
after that divide 12.5/2
Then you get 6.25
Hope it helps!
i think C the higher the frequency the lower the energy of light.
