Aloop-the-loop has a circular arc, with a marble that can run along a track and traverse the entire inside of the loop. when the marble is precisely at the top of the inside loop, it has its minimum speed. ~v what do we know about the direction of the net force on the marble at this point, the top of the loop? a. the net force is instantaneously in the direction of the marble’s velocity b. the net force is instantaneously in the opposite direction to the marble’s velocity ~v. c. the net force is vertically downward. d. the net force is vertically upward

According to rutherford's nuclear theory, most of the volume of an atom is , so the volume of a hydrogen atom cannot be mostly due to the proton.according to rutherford's nuclear theory, the core of an atom (nucleus) contains most of of an atom and is , so the majority of the mass of a fluorine atom cannot be due to its nine electrons.according to rutherford's nuclear theory, the number of negatively charged particles outside the nucleus the number of positively charged particles within the nucleus, so a nitrogen atom has 7 protons and 7 electrons, while a phosphorous atom cannot have 15 protons and 150 electrons.word bank: dense, empty space, more than, mass, particles, the same as, less than, positively charged, negatively charged
