Acanon ball fired horizontally from a cliff has a velocity directed at 60 below horizontal from a cliff has a velocity directed at 60 below horizontal when it hits the ground 3.0 seconds later. a.) how high is the cliff? b.) how far from the base of the cliff does the canon ball land?

True or false a high force means an object is moving fast100 points!

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

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.
