Answer:
The balance will be upset and it will tip to the side of the still pumped ballon.
Explanation:
Given that the balloons are pumped to more than atmospheric pressure it means that the air inside has a higher density than the air outside. If you punture one balloon the air will be released and now you have on both sides the weight of the balloons itselves, but on the side of the still pumped balloon you will have a greater amount of air (is more dense) so more weight. Considering this, the balance will be upset and it will tip to the side of the still pumped ballon.
Answer:
Gravity always pulls the ball toward the center of earth (the ground).
Explanation:
Answer:
(a) =34.0J
(b) = 13.038m/s
(c) =
Explanation:
(a) mass (m) =0.45kg
Height(h) =8.5m
Gravity (g) =10m/s^2
But P. E (Potential Energy) = mass × gravity × height
P. E = 0.45×10×8.5
P. E = 34.0J
(b) using v^2=u^2 - 2gs
Where v = final velocity
u= initial velocity
g = gravity
s =distance
But at maximum height <u>v</u><u> </u>=0
0^2= u^2 - 2gs
Transpose u^2 we have
u^2 = 2gs
u^2 = 2×10×8.5
u^2 = 170
u = square root of 170
u = 13.038m/s
