Iron has a specific heat of o.45 J/g °C. Removing -1.16 E 2 J of energy lowered the temperature of iron from 89 °C to 26.41 °C. What was the mass of the iron?

m = 4.11 grams

Explanation:

Given that,

The specific heat of Iron, c = 0.45 J/g°C

Heat removed,

Initial temperature,

Final temperature,

We need to find the mass of the iron. We know that the heat removed in terms of specific heat is given by :

So, the mass of the iron is 4.11 grams.

i think it's 35 meters

wavelength divides in half and speed stays the same.
