Lenny accidentally drops his matchbox car into a graduated cylinder. the car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. determine the density of the matchbox car. the formula for density is d = m v . a) 0.5 g/ml b) 2 g/ml c) 15 g/ml d) 50 g/ml

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Acar is traveling 35 mph on a smooth surface . if a balanced force is applied to the car what happens?

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
