In the movie Back to the Future, Marty travels back in time to 1955. In 1955, the only available light bulbs in the United States were incandescent bulbs. Assume that last year, you traveled back in time to 1955 and changed all the light bulbs in a single average American household (45 light bulbs) from 75-watt incandescent bulbs to the corresponding 17-watt LED bulbs. The estimated usage is 3 hours per day , at a cost of $0.11 per kilowatt-hour . Based on energy cost alone - not considering the cost to replace any light bulbs and not considering any changes in energy cost with time - how much money in dollars would this household have saved over a 66-year time span (from 1955 to 2021) by changing from incandescent to LED bulbs?
For the Following question Graph all 4 : [I just need all 4 graphs and please explain and make clean solution] Position vs time Velocity vs time Acceleration vs time Force vs time [For your convenience, I have solved the numerical solutions for the problem] (Please Look at the picture since it is much cleaner) Question : A 550 kilogram mass initially at rest acted upon by a force of F(t) = 50et Newtons. What are the acceleration, speed, and displacement of the mass at t = 4 second ? a =(50 e^t)/(550 ) [N/kg] v = ∫_0^t▒(50 e^t )dt/(550 )= v_0 +(50 e^t-50)/550=((e^t- 1))/11 x = ∫_0^t▒(e^t- 1)dt/(11 )= x_0 +(e^t- t - 1)/(11 ) a(4s)=(50*54.6)/550= 4.96[m/s^2 ] v(4s)=((e^4-1))/11= 4.87[m/s] x(4s)=((e^4- 4 - 1))/11= 4.51 [m]
The title of our study is "Design and Fabrication of an Agricultural Spraying Attachment for an Autonomous Rover" we need help in the machine design part of our study, specifically Pump selection, battery selection, and center of gravity computation I already sent you the image of the rover Rover weight capacity 35 kilo grams (payload) Rover measurements: Wheel distance - 14.5 inches and 8.5 inches Rover platform size (width & length) 14.4 inches x 10.4 inches Height- 15.8 inches. Water tank selection More or less 25 liters *For tank selection we need to justify the size with the center of gravity, proving that is the maximum dimension or liters of the tank because the center of gravity will be higher making the rover prone to toppling Pump selection *Our sprayer design has two nozzles which splits using a tee splitter, we need to find the size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer has a 12V pump and a pressure from 0.2 to 0.45 mpa…
1. Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2. Based on data on the rate of energy consumption per year from question no. 1, if the growth rate energy 2.5% per year, calculate the doubling time (td) and what is the approximate rate of energy growth in 2021.
Newton’s 2nd Law Lab (Modeling friendly lab) Go to the PhET simulation Forces & Motion. https://phet.colorado.edu/sims/html/forcesandmotionbasics/latest/forcesandmotionbasics_en.html Select “Acceleration” Click to show Forces, Sum of Forces, Values, Mass, and Acceleration. There are two experiments for this activity – make sure you include both. Experiment #1: Acceleration vs. Force In this lab you will determine the relationship between acceleration and net force. Choose a mass at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Applied Force. Graph Acceleration vs. Net Force. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Applied Force information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best –…
The 1st law of thermodynamics is ΔU = Q –W. Use this statement of the 1st law to show (mathematically) its equivalent statement: “Total energy of the universe is constant”. Here, the universe can be defined as: system + surroundings (everything but the system –everything outside the system). (Hint: this can be shown by two ways-you may either treat system and surroundings as two systems next to each other, or you may treat system + surroundings (universe) as one system.)
The Ideal gas law shows the relationship between some common properties of ideal gases and is written as PV = nRT. P = pressure, V = volume, n = number of moles of ideal Gas, R = General gas constant = 8.314 kJ/(kmol.K) and T = absolute temperature. 5 mol ideal gas at 22°C is placed in a cube with edge lengths of 0.750 meters. Calculate the pressure of the Ideal gas as [Pa].
The amount of time it takes for a pendulum to swing “to-and-fro” through one complete cycle is called the “period” and is calculated using the following equation: where T = period in seconds, I = mass moment of inertia, m = mass of pendulum in kilograms g = gravitational acceleration, 9.8 m/s2, h = effective length of pendulum in meters What is the appropriate unit for I if the preceding equation is to be homogeneous in units? Please show all of your work.

Use of Infinite Sequences and Series in Problem Solving of Special Theory of Relativity. A spacecraft travels fast the earth has a greater velocity (ⱱ) which approximates the speed of light. The time (to) measured in the spacecraft is different from the time (t) measured on earth. The time difference is given, to = t √1- ⱱ 2/c2 = t (1 – ⱱ 2/c2)1/2.
