Hi, thank you for posting your question here at Brainly.
To compute for the change in potential energy, the equation would be:
delta PE = mg*delta h
delta PE = 0.5*9.81*(2-1.8)
delta Pe = 0.98 J
The potential energy is converted to kinetic energy.
Answer:
The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
Explanation:
The one which satisfies Reynold's number and condition for transition from laminar/lamellar flow to turbulent flow maybe
Answer:
Total distance does the grasshopper travel before the cars hit is 150 m
Explanation:
Each car moves x=100 m before they collide. Both the cars moving in constant velocity. time taken t by each car is

where x is the distance traveled with velocity v

The insect is moving through this time period with a constant velocity of 15 m/s
The distance traveled by grasshopper is
