Consider the following statements and decide which of the listed scientists was responsible for each. You will use each scientist's name only ones. Dalton Thomson Rutherford Bohr

a. Believed that atoms were small indivisible particles
b. Developed the model of the atom that we still use today
c. Shot positively charged particles at gold foil, leading to discovery of the nucleus.
d. believed that the atom was a positive clump with negative charges embedded throughout, like a "chocolate chip cookie model"

Need in all of themmm only answer if you know plsssss

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?
