Answer:
Mass is the measure of an object's matter (what it's made up of). The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system.
B. An increase in your mass
Because acceleration is inversely proportional to the mass of the object.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
Answer: A) False; B) False; C) True; D) False
Explanation: In order to explain this problem we have to take into account the expresion of the resistence of the condutor wire, which os given by:
R=ρ*L/A where ρ, L and A are the resistivity, length and area of the conductor.
As it can be seen, the resitence is inverse to the area so when the diameter decrease the resistance should increase its value. (A, C).
The resistivity does not depend on the length or diameter of the wire, only it depends on the material use to made the wire. (B,C and D).
