PLEASE ANSWER:) A block of aluminum at 204°C is put into 1.00 kg of water at
24.0°C. They come to equilibrium
at 28.5°C. What was the mass of
the aluminum block?
Aluminum
c = 900 J/(kg*c)
water
c = 4186 J/(kg*C)
(Unit = kg)

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
