Suppose 100 g of water at 50°C is placed in contact with 200 g of iron at 30°C. The final temperature of the mixture is 46.5°C.

a. What is the energy gained by the iron if the specific heat capacity is .45 J/gºC?

b. What is the energy lost by the water if the specific heat capacity is 4.18 J/g°C?

Ithink they do have the same properties just in less quantities i think

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.

The speed was not exceeded so it was slow

For me a person with a phd and who knows what there talking about.i know the chances of a radiation leak is low but if it does the area within a 96.3 mile radius would be unusable because of contamination
