After 1911, most scientists accepted the theory that the nucleus of an atom was very dense and very small and had a positive charge. what led scientist to accept this theory?

a) dalton’s theory of the atom was over 100 years old

b) scientists before 1911 used the scientific method of inquiry improperly

c) a new model proved that the quantum theory of the atom was inaccurate

d) rutherford did an experiment firing alpha particles at a thin piece of gold foil

I believe it is D

Explanation:

since Rutherford's explanation, when he made it in 1911, was that scattering was caused by a hard, dense court to centre of the Adam, which is the nucleus and he used Alpha particles to observe the scattered backwards from a gold foil

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
