<span>If Paul and Ivan has a speed of 5 meters/second in which their combined mass is 50 kg. To increase the bike's kinetic energy, Paul must increase its speed as well. Increasing his speed allows an increase in momentum of them running the bike. The kinetic energy equation is KE = 0.5mv</span>² where m is mass, v is speed and KE is kinetic energy.
The choices are confusing. Air, oil, and alcohol are fluids at any reasonable temperature. Dry cement is not.
energy. It will not disrupt the picture developing process by overexposing too much light on the film.
Answer:
Three, the liquid in the man's cup, the stove is solid, and the air around them is a gas
Explanation:
Answer:2.6 h
Explanation:
Given
Total Trip distance=450 miles
Meeting starts after 10.8 hours
safe Fastest speed is 55 mi/h
so if he drives all the to the meeting with max speed then it takes 
and total allowable time is 10.8
Therefore longest time he can spend over dinner is
