Uppose one gallon of gasoline produces 1.17×108 j of energy, and this energy is sufficient to operate a car for 18.3 miles. an aspirin tablet has a mass of 319 mg. if the aspirin could be converted completely into thermal energy, how many miles could the car go on a single tablet?

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
