How much heat is absorbed by a 26g iron skillet when its temperture rises from 11°c to 22°c?

Heat energy is the amount of heat energy in joules gained by a substance when its temperature is raised by 1 degree Celsius per kilogram.

So to find its heat energy we will use the formula Q=mc( delta t)
(NB: im not able to type delta t so to get an idea it is a small triangle with t attached to it indicating change in temperature.
Then we put the values :
Q=(0.026)(500)(22-11)
m_ is mass converted to kilograms
c_ is the specific heat capacity of iron according to Wikipedia it is 500J/kg degree Celsius.
delta t_ is change in temprature

finally we calculate and the answer is
130J .

3x + 2x = both people using the same measure of like 5x = x= 25 meters per second. 25ms. it takes them 4 seconds to

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
