Six objects are placed in a 500∘f (260∘c) oven and allowed to reach thermal equilibrium. each object has a mass of 1.0 kg. the specific heat and thermal conductivity of each substance are denoted by c and k. part a rank these objects on the basis of their temperatures when removed from the oven. rank from largest to smallest. to rank items as equivalent, overlap them. view available hint(s)

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?
