Rutherford and his colleagues fired a beam of small, positively charged alpha particles at thin gold foil. some of these alpha particles were deflected at angles as they passed through the foil.

what conclusion did rutherford and his colleagues draw from their results?
a) the atom must contain some neutral charge spread throughout the atom. he called these particles neutrons.
b) the atom must contain some centrally located negative charge. he called this core of negative charge the nucleus.
c) the atom must contain some centrally located positive charge. he called this core of positive charge the nucleus.
d) thomson's plum pudding model of the atom was correct. the atom contains positive charge spread throughout its structure.

How much heat is released upon converting one mole of steam (18.0 g) from 100.0 ∘c to water at 25.0 ∘c? show work and constants, trying to figure out how it works. only given the heat capacity for steam and water so try to only use that

Write a paragraph that provides examples of each stage of volcanic activity, a description of the volcano, and facts about each stage.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
