Answer:
conduction,convection,radiation
Answer/Explanation:
The highest point of potential energy is A, when the ball rolls down the hill potential energy decreases and kinetic energy decreases, but the total energy is constant no matter what. This means the energy does not go away but instead is transferred to a different form.
A: most potential and least kinetic
B: losing potential gaining kinetic
C: losing more potential and gaining more kinetic
D: most kinetic and least potential
E: Gaining potential and losing kinetic
F: Gaining more potential and losing more kinetic
G: more potential than kinetic but not the most potential

C. Reduce friction between its moving parts
Distance traveled = 300 km
Time of travel = 3.6 x 10³ s
Average speed = distance/time
= (300 x 10³ m)/(3.6 x 10³ s)
= 83.3 m/s
Answer: (4) 83.3 m/s
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
