The answer to Willem's experiment are as follows;
A) The two other measurements Willem will require to calculate the specific heat capacity of copper are;
- The mass of the copper block
- The change in temperature of the copper block after heat is supplied.
B) The block must be well insulated to ensure no heat energy is lost to the surrounding by conduction, convection and radiation and hence, all heat supplied is used to effect a change in temperature in the copper block as intended.
C) If the block is poorly insulated, energy is lost and hence, the result would be too high because more energy would be consumed in the process.

An object in motion will continue to move in the same direction and with the same speed unless acted upon by an unbalanced force. states that forces occur as equal and opposite pairs. The strength of the force is related to the mass of the objects and the distance between them.
Answer:
A. it is near the inside surface of the balloon
Explanation:
As we can see in the question shown above, the electric charge is distributed on the surface of a spherical conductive envelope, a balloon. This means that the surface of the balloon becomes automatically energized and the regions closest to that surface experience greater electrical force. With this we can affirm that the center of the balloon has a lesser electrical force, since it is the region farthest from the surface.
Based on this, we can say that the particle that is inside the balloon will be subjected to a greater electrical force when it is close to the inner surface of the balloon.
