The cart would travel 2 meters. If at first, the cart moving 0.5 m/s only traveled 1 meter when the air was shut off, we can assume that the doubling of the speed also doubles the distance traveled when the air is shut off again.
Answer:
Newton's corpuscular theory stated that light consisted of particles that travelled in straight lines. Huygens argued that if light were made of particles, when light beams crossed, the particles would collide and cancel each other. He proposed that light was a wave.
The second choice is the answer
Answer:
Left side and center of the periodic table: metals
Right side of the periodic table: Nonmetals
Zigzag line toward right side of the periodic table: Metalloids
Explanation:
Answer:
44.1 m
Explanation:
initial velocity of ball, u = 0
height of building, H = 106 m
g = 9.8 m/s^2
t = 3 second
Let the ball travels a distance of h in first 3 seconds.
Use second equation of motion
h = 0 + 0.5 x 9.8 x 3 x 3
h = 44.1 m
Thus, the distance traveled by the ball in first 3 seconds is 44.1 m.
