Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
