In the Millikan oil droplet experiment, the oil is sprayed from an atomizer into a chamber.The droplets are allowed to pass thro

ugh the hole into the chamber so that their fall can be observed. The top and bottom of the chamber consist of electrically charged plates. The upper plate is positively charged, and the lower plate is negatively charged. X rays are introduced into the chamber so that when they strike the oil droplets, the droplets will acquire one or more negative charges. The electric field (voltage) is applied to the metal plates.Which of the following applies? Can have more than one answer.a. In the presence of an electric field, the negatively charged oil droplet moves freely toward the negatively charged plate.b. In the absence of an electric field, the oil droplet falls freely due to the gravitational force.c. If Fe is greater than Fg , the negatively charged oil droplet will move freely toward the negatively charged plate.d. If Fe is increased until it is equal to Fg , the negatively charged oil droplet will remain stationary.

uranium-232 has a half-life of 68.8 years. after 344.0 years how much uranium-232 will remain from a 125.0g sample
GaryK [48]

Answer:

4 grams

Explanation:

A = A₀e^⁻kt

A₀ = 125.0 grams

k= 0.693/t(1/2) = (0.693/68.8) yrs⁻¹ = 0.01 yrs⁻¹

t = 344.0 years

A = 125.0g·[e^-(0.01yrs⁻¹)(344.0yrs)] = 125(0.032)grams = 4.000g (4 sog. figs. based on A₀ = 125.0 grams)
