- For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting nucleus will now change (as compared to your starting nucleus) by O A. zero O B. minus 1 OC. minus 2 O D. minus 3arrow_forwardInstructions: Your task is to create a model in response to the prompts in the question below. Be sure to apply a model from this class and include the relevant diagram(s) for that model. And don’t forget to use the Claim, Evidence, Reasoning framework to present your solution. Phenomenon: Runaway Truck Ramp A truck was driving on a highway at 30 m/s when its brakes gave out. The driver steered it onto a “runaway truck ramp”, consisting of an upward ramp (rising 12 meters vertically over 120 meters horizontally), and ending with a compressible barrier which you can model as a giant spring with spring constant “k”. The compressible barrier can be compressed by a maximum 0.5 meters before it stops working. Graphic attached Values: Mass of the truck: 20 metric tons (1 metric ton = 1000kg). Mass of the driver: Choose a reasonable value. Truck Ramp Dimensions: 12 meters vertical, 120 meters horizontal Spring constant k= 6.0 x 107 J/m2. Part 1: Big…arrow_forwardUse GFSA (Given, Find, Solution, and Answer) on the given space below. Encircle your final answer, write it in scientific notation with 2 decimal places. 1. What is the power input to an electric heater that draws 4 A from a 140-V outlet? 2. If R1 = 2Ω, R2 = 4Ω, R3 = 6Ω, determine the electric current flows in the circuit below using Kirchhoff’s law.arrow_forward
