Ответ:
1 mole of every substance has 6.022 × 10^23 particles. This is called Avagadro's constant
Ответ:
0.952 ft/s^2, 125 lb 4006.25 lbf
Explanation:
mass of balloon, m = 125 lb
Weight of balloon, W = 119 lbf
As we know that
Weight = mass x acceleration due to gravity
W = m g
119 = 125 g
g = 0.952 ft/s^2
The value of local acceleration due to gravity is 0.952 ft/s^2.
When g = 32.05 ft/s^2
mass = 125 lb
Mass of a material remains constant but the weight changes.
W = m x g
W = 125 x 32.05 = 4006.25 lbf
