The marbles that are 'more energetic' fall out of the tray, in the same way particles have enough energy to escape and turn into a gas.
Answer:
ACCELARATION
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
Explanation:
pls mark as brailiest
If we ignore air resistance, as we always do,
there is no horizontal acceleration.
Gravity acts only in the vertical direction, and
no other forces act on the ball after the punt.
The answer is 388 800 sec
Speed = distance ÷ time
Change 20 minutes to seconds...
20 × 60 = 120 seconds, because seconds (s) is the SI unit for time.
speed = 1000m/120s
= 8.33 m/s
