speed increases with temp maybe
3. An object will float if its density is less than the matter it is submerged in.
If it sinks in water, its density is more than 1. If it floats in glycerin, its density is less than 1.26.
Answer:
Both balls have the same speed.
Explanation:
Janelle throws the two balls from the same height, with the same speed. Both balls will have the same potential and kinetic energy. Energy must be conserved. When the balls pass Michael, again they must have the same potential and kinetic energy.
Answer:
2 min 40 s.
Explanation:
Distance = 800 ft
Speed (walking speed) = 300 ft/min
Speed = distance/time
Time, t = 800/300
= 8/3
= 2 min 40 s.
