I believe the correct answer is false. <span>The parts of a mixture do not keep their own properties when they are combined. When they are combined, they exhibit or behave with different properties since each atom is bonded which gives them unique properties. Hope this helps.</span>

it's because the eclipse hides the moon and Venus and the sun
Explanation:
I found it
Answer: v2 = -50.8m/s
Therefore, the speed of the baseball is 50.8m/s away from the bat. (Reverse direction)
Explanation:
Using the law of conservation of momentum:
The impulse of the bat = change in momentum of the baseball
Ft = ∆M
Ft = m1v1 - m2v2
Since m1 = m2 = m (the mass remains unchanged)
Ft = m(v1 - v2) .....1
Given:
Force F = 8900N
Mass m = 0.145kg
time t = 1.3 × 10^-3 s
Initial velocity v1 = 29m/s
Substituting into eqn 1
8900(1.3×10^-3) = 0.145(29-v2)
29-v2 = 79.79
v2 = 29 - 79.79 = -50.8m/s
v2 = -50.8m/s
Therefore, the speed of the baseball is 50.8m/s away from the bat.
The two bols of ice creams are composed of vanilla the same subtances
Answer:
37.5 m/s
Explanation:
Using the law of conservation of energy, potential energy equals kinetic energy hence
Therefore
where g is the acceleration due to gravity, m is the mass of the object, h is the height and v is the speed of the roller coaster
Taking g as 9.81 then
