A 52.0g sample of iron is put into a calorimeter (see sketch at right) that contains 100.0g of water. The iron sample starts off at 93.9°C and the temperature of the water starts off at 18.0°C. When the temperature of the water stops changing it's 22.9°C. The pressure remains constant at 1atm. Calculate the specific heat capacity of iron according to this experiment. Be sure your answer is rounded to the correct number of significant digits.

Argon, neon, and xenon are examples of

What would people living along the coast in south florida do if there was a hurricane warning? move to locations away from the water flock along coasts to watch the natural phenomenon buy instruments to predict the exact location of the hurricane measure water levels to know the exact time of the hurricane

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
