Formula Quiz Answers Solutions V DT 75 km1

Formula Quiz Answers & Solutions

V = D/T 75 km/1. 5 hr = 50 km/hr T = D/V 1075 miles/50 mph = 21. 5 hours D=Vx. T 30 km/hr x 2 hrs = 60 km

90 km/hr – 50 km/hr = 40 km/hr/5 sec = 8 km/hr/s Force = Mass X Acceleration 300 kg x 4 m/s 2 = 1200 Newtons Weight = Mass x Acceleration of Gravity 60 kg x ~10 m/s 2 = 600 Newtons Work = Force X Distance 50 N x 80 m = 4000 joules

Distance = Work/Force 250 joules/200 N = 1. 25 meters Force = Work/Distance 20 joules/2 meters = 10 Newtons Effort distance/resistance distance 8 m/2 m = MA of 4 Resistance force/effort force 600 N/200 N = MA of 3

Density = Mass/Volume 47. 25 g/17. 5 cm 3 = 2. 7 gm/cm 3 Mass = Density x Volume 2. 0 gm/cm 3 X 5 cm 3 = 10 g Volume = Mass/Density 320 g/4 g/cm 3 = 80 cm 3

Q = mcΔT 20 g x 4. 184 J/g. OC x 20 OC = 1673. 6 Joules 455 J = 25 g X c X 130 OC 455 J = 3250 c (then divide both sides by 3250) 0. 14 J/g. OC 41840 J = ? g X 4. 184 J/g. OC X 5 OC 41840 J = 20. 92 J/g (then divide both sides by 20. 92) 2000 g

I = V/R 260 v/0. 4 Ω = 650 amps V = IR 15 amps X 225 Ω = 3375 volts R = V/I 2400 v/250 amps = 9. 6 Ω
