Timed!! please help i would really appreciate it! i will try to give brainliest! Craig rides a skateboard on the sidewalk in front of the mall, traveling at 18km/h. How much time would it take him to travel 6.0km?

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.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?
