To determine the specific heat capacity of copper, Alyssa performed an investigation by which she dropped a heated piece of copper into a calorimeter. Some of the data Alyssa recorded is given in the following table. The experimental specific heat capacity of the copper is _J/g°C. Use three significant digits in your answer.

the answer is a. at the equator

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.
