Round each number to reasonable number of significant digits. If you are not familiar with the topic or unit, you will need to research it on google. Remember to cite all your references at the end of this document in MLA Format. a) The distance from Tampa to New York 1499.2 miles b) The flight time from Charlotte to Atlanta 1 hr 11 minutes c) The mass of a typical paperclip 1.125 grams Problem 6 (2 points/0.5 points each) State whether each of these is reasonable. If you are not familiar with the topic or the unit, you will need to research it on google. Remember to cite all your references at the end of this document in MLA Format. a) You determine that a sewage treatment plant for a community of 10,000 people must handle 100,000 pound-mass of sewage effluent per day. Since a gallon of water weighs about 8 pound-mass, this is about 1.25 gallons per person per day. b) You design a playground equipment swing. The top support for the swing is 10 feet above the ground. You calculate that a child using one of the swings will make one full swing (forward, then backward) in 4 sec. C) You calculate the speed of a pitched baseball to be 2 x 1013 millimeters per year. (Convert to miles per hour) d) You have measured the force of a hammer hitting a nail by using a new sensor. The result is 60 million dynes.

Answer 1

Solutions Date: / / _Page no:_ - al Estimation of unit :- The distance from Tampa to New Yoak - 1499.2 miles I miles = 1.6 k.m. (Kilometre). so 1499.2 miles ä 2399 kilometers. The flight time from Charlotte to - Atlanta - 1hr 11 minutes. c) The mass of ho ho - 1.18 ~ 1.2 hr. a typical paperclip :- = 1.125 grams. - 1.13 gsoms - Lot solution 6 a Total Number of people = 10,000 T 1 gallon water weighs = 8 pound ( sewage/ day 1 person handle 1.25 gallons sewage - effluent per day a Signature

Total sewage ebblerent par le per day = 100000 pound. = kx 100000 gallons 12500 gallons/day 1.25 gallon sewage must handle by one person per day 1 gallon sewage must handled perday = t person so 12500 gallons non = vze x12500 - = 10,000 person Yes it is Reasonable. b) Swing design :- 125 TEGUISTITIATIITTI1177777 As As ffect feet 13 fect se Let consider ground Allowance 3 feet Max angle move forward = 45° from Equilibrium position Signature

so. Sin45 Sinas - - - - Date: _____ Page no: - year Si= 7 sin45 ~ 5 feet so Total distance moved - forward & backward _ =$+$z_-25 = 2x5=10 feet O speed of a pitched Ans baseball = 2x1013 mm/year = 2x10x lóxió? km/u - 2x101x10 x 0,62 miles 1 year = 8760 hr = 21.242 x107 mites 8760 hour - 1417.80 miles/hour d . 1 Newton = los dynes So 1 dynes = 10s Newton. 60x106 dynes = 6x107x105 Newton : 600 Newton = Answer Tkm:0.6211 miles AN Signature
