Why do you want the water to drip off the metal before it is placed in the calorimeter?

(a) the mass and the initial temperature of the calorimeter water will be incorrect and affect the calculation of the specific heat capacity of the metal.
(b) the mass of the metal will be incorrect and affect the calculation of the specific heat capacity of the metal.
(c) both a and b.

Aphysical change is a change in the size, shape,, or stafe of matter true or false

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
