Which was a testable idea that Ernest Rutherford developed in his experiments? - The positive charge in an atom is concentrated in one location. - Atoms are not divisible into smaller particles. - It is impossible to define the mass of an atom.

Consider an unknown charge that is released from rest at a particular location in an electric field so that it has some initial electric potential energy.

What factors determine the magnitude of the electric force between two particles? a. charge and distance b. mass and distance c. charge and density d. mass and charge

How did scientists refute the early atomic theory claim that atoms were indivisible? Select all that apply.

Which type of star is the sun? red giant black dwarf main-sequence black hole

StA A boat takes off from the dock at 2.5 m/s and speeds up at 4.2 m/s2 for 6.0 s. How far has the boat traveled? Round your answer to the nearest whole number.

In Part A, you determined that the heat added to the coffee is what you got. If it takes 4.2 J of energy to raise the temperature of 1.0 mL of coffee by 1.0∘C, then it should take twice as much energy to raise the temperature of 2.

The brightness of a star depends on what three factors?

What is most likely the relationship between Mendel's rules of genetics and Darwin's idea of biological evolution? Mendel's genetics states laws that are now part of the theory of biological evolution.
