Nswer one of these two questions in the space below 1) a sample of 40 ml of ethanol (density- 0.79 g/ml) with a temperature of 80 celslus is poured into 60 ml of water (density 1.00g/ml) at a temperature of 25 celsius. it the specific heat of ethanol is 2a6」rg-c) and that of water is 4.183/g: cl what is the final temperature of the mlxture? 2) you have taken your two nephews to the amusement park. you are on a beeline to the cotton candy stand, when your younger nephew spots the fun house and your older nephew sees the roller coaster. your younger nephew puils on your left hand with a torce of 380 newtons at a 37 degree angle with respect to your current heading, while your older nephew pulls newtons, what is the magnitude and direction of the net force acting on you with respect to your original bearing? on your right hand in the other direction at an 60 degree angle with a force of 420

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
