- For the following homework problems please show all of your work. 1. If the energy of a photon is given by the equation E = hv, where h is known as Planck's constant, and has the value of h = 4.136 x 10-15 eV -s, then complete the following table. Please note: the unit called an electron volt (eV) is a unit of energy whose value is compa- rable to the values seen in atomic transitions, and a Hertz is Hz = 1/s.

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_forward
- Instructions: 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_forwardPlease answer part A,B,C.

Thank you for your help!arrow_forwardhones Cop the problem first beföre you show your solutions. Place the honesty clause and your signature at the beginning of your work. No erasures or alterations allowed. Box all your final answers. Submit a soft-copy output in pdf format then upload it to your section's google drive's folder. I. Vo Fig. 4: Projectile Motion IV Suppose that the motion of the projectile shown in the figure above is ideal without friction. Choose the correct statements on the motion in 1 and 2 below for this assumption. 1. (a) The value of v, is continuously positive and decreases only marginally over time. (b) The value of v, varies from positive to negative over time. (c) The value of v, is always negative and increases marginally over time. (d) The value of v, is still positive and constant over time. (e) The value of v, varies from negative to positive over time. 2.arrow_forward
